Immigration-Related Detention: Current Legislative Issues

Summary
As Congress considers addressing some of the problems in the nation’s immigration system, the
detention of noncitizens in the United States may be an issue as Congress may chose to reevaluate
detention priorities (i.e., who should be detained) and resources. Under the law, there is broad
authority to detain aliens while awaiting a determination of whether the noncitizen should be
removed from the United States. The law also mandates that certain categories of aliens are
subject to mandatory detention (i.e., the aliens must be detained). Aliens subject to mandatory
detention include those arriving without documentation or with fraudulent documentation, those
who are inadmissable or deportable on criminal grounds, those who are inadmissable or
deportable on national security grounds, those certified as terrorist suspects, and those who have
final orders of deportation. Aliens not subject to mandatory detention may be detained, paroled,
or released on bond. The priorities for detention of these aliens are specified in statute and
regulations. As of December 13, 2011, on an average day in FY2012, 32,953 noncitizens were in
Department of Homeland Security (DHS) custody.
There are many policy issues surrounding detention of aliens. The Illegal Immigrant Reform and
Immigrant Responsibility Act of 1996 (IIRIRA) increased the number of aliens subject to
mandatory detention, and raised concerns about the justness of mandatory detention, especially as
it is applied to asylum seekers arriving without proper documentation. Additionally, as DHS
increases its ability to identify aliens who are subject to removal from local jails in more remote
locations, the nationwide allocation of detention space may become an issue.
The 108th Congress passed P.L. 108-458, the Intelligence Reform and Terrorism Prevention Act of
2004, directing the Secretary of DHS to increase the amount of detention bed space by not less
than 8,000 beds for each year, FY2006 through FY2010; a total of 40,000 beds. Although
Congress increased the bed space between FY2006 and FY2010, the number of beds only
increased by approximately 12,000.
One bill related to immigration detention has received Congressional action in the 112th Congress.
H.R. 1932 was placed on the Union Calendar on October 17, 2011. After a removal order has
been issued against an alien, the law provides that the alien subject to a final removal order be
removed within 90 days, except as otherwise provided in the statute. Certain aliens subject to a
removal order “may be detained beyond the removal period and, if released, shall be subject to
[certain] terms of supervision.” This provision had been interpreted as permitting indefinite
detention where removal was not reasonably foreseeable, but in 2001, the U.S. Supreme Court in
Zadvydas v. Davis, interpreted it as only permitting detention for up to six months where removal
was not reasonably foreseeable. Nonetheless, the U.S. Supreme Court ruled absent clear guidance
from Congress. H.R. 1932 as reported by the House Judiciary Committee, would amend the
Immigration and Nationality Act to allow DHS to indefinitely detain, subject to six-month
reviews, aliens under orders of removal who could not be removed if certain conditions were met.
In addition, in the 112th Congress, other bills have been introduced covering a range of provisions
and perspectives concerning the detention of noncitizens. Several bills—including H.R. 100 and
H.R. 1274—would mandate that DHS increase the amount of detention space. In addition, other
bills (e.g., H.R. 933 and S. 1258) would mandate the propagation of regulations concerning
detainee care, and expand the alternatives to detention program. Other proposed legislation, such
as H.R. 713, would make changes to the mandatory detention provisions, lessening the categories
of aliens required to be detained.

Immigration-Related Detention: Current Legislative Issues

Introduction
As Congress considers reforms to the nation’s immigration system, the detention of noncitizens
(aliens)1 in the United States will likely be an issue. Congressional interest in the policy of
detaining noncitizens in the United States while determining whether noncitizens should be
removed from the United States tends to be varied. For example, while some want to increase the
categories of aliens who are detained and increase the amount of detention space, others want to
create alternatives to detention and exempt asylum seekers from mandatory detention. In addition,
immigration enforcement activities affect the need for and allocation of detention resources. For
example, as the Department of Homeland Security (DHS) expands programs to locate removable
aliens from jails throughout the country, DHS may need additional detention beds in areas of the
United States where traditionally there has not been a need for detention space.2
The Immigration and Nationality Act (INA) provides broad authority to detain aliens while
awaiting a determination of whether they should be removed from the United States and
mandates that certain categories of aliens are subject to mandatory detention (i.e., the aliens must
be detained) by DHS. Aliens not subject to mandatory detention may be detained, paroled, or
released on bond. “Enemy combatants” at the Guantanamo U.S. military base in Cuba are not
under the authority of DHS, nor are noncitizens incarcerated in federal, state, and local
penitentiaries for criminal acts.
Any alien can be detained while DHS determines whether the alien should be removed from the
United States. The large majority of the detained aliens have committed a crime while in the
United States, have served their criminal sentence, and are detained while undergoing deportation
proceedings. Other detained aliens include those who arrive at a port-of-entry without proper
documentation (e.g., fraudulent or invalid visas, or no documentation), but most of these aliens
are quickly returned to their country of origin through a process known as expedited removal.3
The majority of aliens arriving without proper documentation who claim asylum are held until
their “credible fear hearing,” but some asylum seekers are held until their asylum claims have
been adjudicated.
There are many policy issues surrounding detention of aliens, including concerns about the
number of aliens subject to mandatory detention and the justness of mandatory detention,
especially as it is applied to asylum seekers arriving without proper documentation. Some have
raised concerns about the length of time in detention for aliens who have been ordered removed.
Additionally, issues have been raised about the amount of detention space available to house DHS
detainees or the nationwide allocation of the space.

1 An alien is “any person not a citizen or national of the United States” and is synonymous with noncitizen.

Immigration-Related Detention: Current Legislative Issues

Overview of Noncitizen Detention
Changes in Authorities with the Creation of the
Department of Homeland Security

The INA provides the Attorney General with broad authority to detain aliens while awaiting a
determination of whether they should be removed from the United States,4 but the creation of
DHS moved the administration of detention of noncitizens from the Department of Justice’s
Immigration and Naturalization Service (INS) to DHS.5 While current regulations vest all
authorities and functions of the DHS to administer and enforce the immigration laws with the
Secretary of Homeland Security (hereafter the Secretary) or his delegate,6 it can be argued that
the language in the Homeland Security Act of 2002 (HSA)7 has left the Attorney General with
concurrent authority over immigration law.8 The Ninth Circuit in Armentero v. Immigration and
Naturalization Service
, for example, appeared to struggle with determining who should be the
correct respondent in a habeas petition filed by an INS detainee. The Ninth Circuit stated:
Because the Homeland Security Act transfers most immigration law enforcement
responsibilities from the INS, a sub-division of the Department of Justice, to the BTS
[Directorate of Border and Transportation Security], a sub-division of the Department of
Homeland Security, the extent of the Attorney General’s power to direct the detention of
aliens is unclear.9
The court further concluded that “[u]ntil the exact parameters of the Attorney General’s power to
detain aliens under the new Homeland Security scheme are decisively delineated, we believe it
makes sense for immigration habeas petitioners to name the Attorney General in addition to
naming the DHS Secretary as respondents in their habeas petitions.”
In addition, both DOJ, through the Executive Office of Immigration Review (EOIR), and DHS
have authority for determining bond for aliens. Officials within DHS also make bond
determinations that may or may not subsequently come before EOIR. The Board of Immigration
Appeals (BIA), the appellate body within EOIR, hears appeals from matters decided by
immigration judges. The BIA has jurisdiction to consider appeals of various decisions now made
by immigration officials in DHS, including the granting of bond.

in part, by §103 of the INA, which was amended by the Homeland Security Act of 2002 (P.L. 107-296) to charge the
Secretary of DHS with the administration and enforcement of the INA.

Immigration-Related Detention: Current Legislative Issues

The Attorney General has final say in matters of immigration law that come before EOIR.10 For
example, on April 17, 2003, the Attorney General released a decision11 that instructs immigration
judges to consider “national security interests implicated by the encouragement of further
unlawful mass migrations” in making bond determinations for unauthorized migrants who arrive
in “the United States by sea seeking to evade inspection.” In the decision, the Attorney General
states that he retains the authority to detain or authorize bond for aliens, but the authority is
“shared” with the Secretary since DHS’s officials make the initial determination whether an alien
will remain in custody during removal proceedings.12
Statutory Authority for Detention
The INA gives the Attorney General the authority to issue a warrant to arrest and detain any alien
in the United States while awaiting a determination of whether the alien should be removed from
the United States.13 As a result of the HSA, the daily responsibility for detaining aliens resides
with the Secretary of Homeland Security, but under law the Attorney General may still retain the
authority to arrest and detain aliens. The Illegal Immigrant Reform and Immigrant Responsibility
Act of 1996 (IIRIRA)14 amended the INA, effectively specifying levels of detention priority and
classes of aliens subjected to mandatory detention. Mandatory detention is required for certain
criminal and terrorist aliens who are removable, pending a final decision on whether the alien is
to be removed. No bail is available and only a hearing can determine whether the alien qualifies
as a criminal or terrorist alien. Aliens not subjected to mandatory detention can be paroled,15
released on bond,16 or continue to be detained. Decisions on parole made by the Secretary and
bond decisions made by the Attorney General are not subject to review.
In October 1998, the former INS issued a memorandum establishing detention guidelines
consistent with the changes made by IIRIRA.17 According to the guidelines, detainees are
assigned to one of four detention categories: (1) required; (2) high priority; (3) medium priority;
and (4) lower priority.18 Aliens in required detention must be detained19 while aliens in the other

15 “Parole” is a term in immigration law which means that the alien has been granted temporary permission to enter and
be present in the United States. Parole does not constitute formal admission to the United States and parolees are
required to leave when the parole expires, or if eligible, to be admitted in a lawful status. Section 402 of the HSA
states: “The Secretary [of the Department of Homeland Security], acting through the Under Secretary for Border and
Transportation Security, shall be responsible for the following: ... (4) Establishing and administering rules, ... governing
the granting of visas or other forms of permission, including parole, to enter the United States to individuals who are
not a citizen or an alien lawfully admitted for permanent residence in the United States.”

categories may be detained depending on detention space and the facts of the case. Higher
priority aliens should be detained before aliens of lower priority.20
Additionally, the U.S.A. PATRIOT Act21 amended the INA to create a new section (236A) which
requires the detention of an alien whom the Attorney General certifies as someone who the
Attorney General has “reasonable grounds” to believe is involved in terrorist activities or in any
other activity that endangers national security. The Attorney General must initiate removal
proceedings or bring criminal charges within seven days of arresting the alien or release the alien.
An alien who is detained solely as a certified terrorist, who has not been removed, and who is
unlikely to be removed in the foreseeable future may be detained for periods of up to six months
only if his release would pose a danger to national security or public safety. The Attorney General
must review the terrorist certification every six months.22
Under the INA, the Attorney General also has the authority to arrest and detain aliens without a
warrant if he has “reason to believe that the alien ... is in the United States in violation of any
[immigration] law and is likely to escape before a warrant can be obtained.”23 Functionally, DHS
is responsible for arresting and detaining aliens. If an alien is arrested without a warrant, a
decision must be made within 48 hours to detain or release the alien. Aliens paroled or released
on bond may be rearrested at any time. On September 20, 2001, the Department of Justice (DOJ)
issued an interim regulation to provide more flexibility in detaining aliens prior to determining
whether to charge or release them. The interim regulation extended the period that an alien may
be detained, pending the determination of whether to arrest, from 24 hours to 48 hours or—in the
event of emergency or extraordinary circumstances—within an “additional reasonable period of
time.” The regulation took effect on September 17, 2001.24
Additionally, after a removal order has been issued against an alien, the law provides that the
alien subject to a final removal order be removed within 90 days, except as otherwise provided in
the statute.25 Certain aliens subject to a removal order “may be detained beyond the removal
period and, if released, shall be subject to [certain] terms of supervision.”26 This provision had
been interpreted as permitting indefinite detention where removal was not reasonably foreseeable,

arriving aliens not in expedited removal and not subject to mandatory detention. Low priority detainees are other
removable aliens not subject to required detention, and aliens who have committed fraud while applying for
immigration benefits with DHS.
19 There are some very limited exceptions to mandatory detention. An alien subject to mandatory detention may be
released only if release is necessary to protect an alien who is a government witness in a major criminal investigation,
or a close family member or associate of that alien, and the alien does not pose a danger to the public or a flight risk.

but in 2001, the U.S. Supreme Court in Zadvydas v. Davis,27 interpreted it as only permitting
detention for up to six months where removal was not reasonably foreseeable.
Local Law Enforcement 28
The INA contains both criminal and civil violations. Historically, the authority for state and local
law enforcement officials to enforce immigration law has been construed to be limited to the
criminal provisions29 of the INA. The enforcement of the civil provisions,30 which includes
apprehension and removal of deportable aliens, has strictly been viewed as a federal
responsibility, with states playing an incidental supporting role.
Although there is debate with respect to state and local law enforcement officers’ authority to
enforce civil immigration law, it is permissible for state and local law enforcement officers to
inquire into the status of an immigrant during the course of their normal duties in enforcing state
and local law. For example, when state or local officers question the immigration status of
someone they have detained for a state or local violation, they may contact an ICE agent at the
Law Enforcement Support Center (LESC).31 The federal agent may then place a detainer on the
suspect, requesting the state official to keep the suspect in custody until a determination can be
made as to the suspect’s immigration status. However, the continued detention of such a suspect
beyond the needs of local law enforcement, and solely designed to aid in enforcement of federal
immigration laws, may be unlawful.32
Mandatory Detention
The law requires the detention of
• criminal aliens;33

Local Police to Enforce Federal Immigration Law
, by Michael John Garcia and Kate M. Manuel.
29 Examples of criminal violations include alien smuggling, harboring of aliens, and trafficking in people, which are
prosecuted in federal courts.
30 Examples of civil violations include being present in the United States without a valid immigration status, or working
without employment authorization which may lead to removal through administrative proceedings through the
Executive Office of Immigration Review.
31 Under current practice in most jurisdictions, state and local law enforcement officials can inquire into an alien’s
immigration status if the alien is being questioned by an officer as a result of a criminal investigation or other related
matters (i.e., traffic violation).

(citing Abel v. United States, 362 U.S. 217 (1960); United States v. Cruz, 559 F.2d 30 (5th Cir. 1977)).
33 Criminal aliens include those who are inadmissable on criminal-related grounds as well as those who are deportable
due to the commission of certain criminal offences while in the United States. An alien is inadmissable for (1) crimes
of moral turpitude; (2) controlled substance violations; (3) multiple criminal convictions with aggregate sentences of
five years or more; (4) drug trafficking; (5) prostitution and commercialized vice; and (6) receipt of immunity from
prosecution for serious criminal offenses (INA §212(a)). An alien is deportable for the following offenses: (1) crimes of
moral turpitude; (2) aggravated felonies; (3) high speed flight; (4) controlled substance violations; (5) certain firearm
offenses; and (6) crimes of domestic violence, stalking, and child abuse (INA §237(a)(2)). Any alien who is found in
the United States who is inadmissable is deportable. Only the following groups of criminal aliens who are inadmissable
or deportable are not subject to mandatory detention: (1) aliens convicted of a single crime of moral turpitude who were

• national security risks;34
• asylum seekers, without proper documentation, until they can demonstrate a
“credible fear of persecution”;
• arriving aliens35 subject to expedited removal (see below);
• arriving aliens who appear inadmissable for other than document related reasons;
and
• persons under final orders of removal who have committed aggravated felonies,
are terrorist aliens, or have been illegally present in the country.36
The USAPATRIOT Act added a section (§236A) to the INA that provides for the mandatory pre-
removal-order detention of an alien who is certified by the Attorney General as a terrorist suspect.
It can be argued that the Attorney General and the Secretary of DHS both have the discretion to
detain any alien who is in removal proceedings, and must detain all aliens who are charged as
terrorists, and almost all aliens charged as criminals upon their release from criminal
incarceration whether they are released on probation or parole.37
Post-removal Order Detention
Prior to 2001, the mandatory detention provisions created in IIRIRA had led to some aliens being
in indefinite administrative custody. These aliens had been ordered removed from the United
States, but were detained because the aliens could not obtain travel documents to another country
or the immigration officials refused to release them. These detainees were often referred to as
“lifers” or “unremovables.”38 Many of these detainees had criminal records, but some simply
lacked immigration status and the ability to return to their country of origin. Some detainees had
been in immigration detention for a longer time period than their criminal incarceration. In 2000,

violence, stalking, and child abuse or neglect.
34 Any alien who is inadmissable or deportable for terrorist activity must be detained (INA §212(a)(3)(B) and
§237(a)(4)(B)).
35 The regulations define an arriving alien as an applicant for “admission to or transit through the United States.” 8
C.F.R. §1.1(q).
36 Prior to IIRIRA, aliens convicted of aggregated felonies who could not be removed could be released.
37 INA §236(c)(1).
38 Most indefinite detainees were from countries that lack normal diplomatic relations with the United States (e.g.,
Cuba, Iran, or North Korea). (The majority of “lifers” were Cubans who came during the Mariel boatlift. The Mariel
boatlift was an influx of asylum seekers during a seven-month period in 1980 when approximately 125,000 Cubans and
25,000 Haitians arrived by boat to South Florida. About 10% of the Mariel Cubans had histories of mental illness or
violent crime.) Other indefinite detainees were stateless people (e.g., Palestinians and persons from the former Soviet
Union who do not meet the citizenship requirements for any of the newly independent states) or persons whose
nationality could not be determined. Other indefinite detainees were from countries that refused to accept the return of
their nationals (e.g., Vietnam, Laos, Cambodia, and the People’s Republic of China) or from countries experiencing
immense upheaval. Others may have been indefinitely detained because the alien had strong ties to the United States,
and only attenuated connections to their country of origin. For example, an alien may be brought by his parents to the
United States as a two-year old, and live in the United States for 40 years without naturalizing. If the person commits a
crime and is removable, his birth country may refuse to take him. For more on the Mariel Cubans see, U.S. House of
Representatives, Committee on Appropriations, A report on the Department of Justice’s management and operation of
programs dealing with the detention, medical care, and outplacement of Mariel Cubans, April 1991.

Immigration-Related Detention: Current Legislative Issues

which was the final year before the Supreme Court ruling limiting the time in detention for aliens
who had been ordered removed, INS estimated that it had 5,000 aliens in indefinite administrative
custody.39
In a 5-4 decision in Zadvydas v. Davis (2001),40 the U.S. Supreme Court held that a statute
permitting indefinite detention would raise serious constitutional problems because the Due
Process Clause of the Fifth Amendment prohibits depriving any person, including aliens, of
liberty without due process of law. Therefore, in keeping with principles of statutory construction
and the absence of clear congressional intent for indefinite detention, the Court read an implicit
limitation into the post-removal detention statute, such that detention is limited to a period
“reasonably necessary” to achieve an alien’s removal. The Supreme Court established six months
after the removal order as the presumptively reasonable period within which to effect removal.
After this period, once an alien shows that there is good reason to believe that “there is no
significant likelihood of removal in the reasonably foreseeable future,” the government must
rebut that showing with sufficient evidence. The Court emphasized that its holding does not mean
that all aliens must be released in six months nor that an alien may not be held until it has been
determined that “there is no significant likelihood of removal in the reasonably foreseeable
future.” The Court suggested that special arguments could be made for a statutory scheme of
preventive detention for terrorists or other aliens in special circumstances and for heightened
judicial deference for executive and legislative branch decisions regarding national security
matters.
In response to this decision, the Attorney General issued regulations governing the review of
post-removal order detention cases for a determination of foreseeability of removal. The Attorney
General issued regulations, effective November 14, 2001, concerning the continued detention of
aliens subject to final orders of removal that are consistent with the Zadvydas decision.41
Subsequently, then Chief Immigration Judge Michael Creppy issued a memorandum on the
Immigration Court’s policy regarding these regulations. The regulations and the memorandum
establish four categories of aliens whose removal from the United States is not foreseeable, but
whom the Attorney General may continue to detain. These “special circumstances” include
• aliens with a highly contagious disease that poses a threat to public safety;
• aliens whose release would cause serious adverse foreign policy consequences;
• aliens detained for security or terrorism reasons; and
• aliens determined to be specifically dangerous.
Of these four categories, only the fourth requires the involvement of the Immigration Court; the
other three remain under DHS discretion.42 Between November 14, 2001, and March 9, 2005,
only 17 aliens whose removal was not foreseeable had been detained under the “special
circumstances.” Two aliens were detained because of serious adverse foreign policy
consequences, and 15 were detained because they were determined to be specifically dangerous.43

Immigration-Related Detention: Current Legislative Issues

In Clark v. Martinez,44 the Court held that the rationale it applied in Zadvydas to aliens who had
been admitted to the United States and were deportable also applied to aliens who had not been
legally admitted into the United States, were found inadmissible and ordered removed, and were
being detained beyond the statutory removal period although removal was not reasonably
foreseeable.45 Accordingly, the six-month presumptive detention period applied. In Zadvydas, the
Court explicitly let stand an older decision which distinguished between the indefinite detention
of an excludable alien (similar to inadmissible alien under current law) who sought to enter the
United States and a deportable alien who had entered the United States.46 Therefore, the Court
had suggested that it might reach a different conclusion for indefinite detention of inadmissible
aliens from the one it reached in Zadvydas for deportable aliens and noted that the statutory
purposes and constitutional concerns for deportable aliens were not the same for inadmissible
aliens. However, in Clark v. Martinez, it decided that to treat inadmissible aliens differently under
the removal statute would render an inconsistent interpretation of the removal statute, where the
statute itself made no distinction between the treatment of inadmissible and deportable aliens.
Justice Thomas criticized the Court’s opinion as departing from its constitutional rationale in
Zadvydas and its suggestion in that case that inadmissible aliens presented a different situation.47
At the same time, Justice Thomas agreed with the Court’s “fidelity to the text” of the removal
statute; he believed that Zadvydas had been wrongly decided and should have been overruled.
Expedited Removal and Detention
Aliens who arrive in the United States without valid documentation or with false documentation
are subject to a process known as “expedited removal,” under which the alien is ordered removed
from the United States, and the removal decision is not subject to any further hearings, reviews,
or appeals.48 Most aliens subject to this process face continuous detention. Aliens subject to
expedited removal must be detained until they are removed and may only be released due to
medical emergency or if necessary for law enforcement purposes. If the arriving alien expresses a
fear of persecution or an intent to apply for asylum, the alien is placed in detention until a
“credible fear” interview can be held. If the alien is found to have a credible fear, he may be

44 543 U.S. 371, 160 L. Ed. 2d 734 (2005). This paragraph was written by Margaret Mikyung Lee, Legislative
Attorney, American Law Division.
45 Inadmissible aliens have not yet been admitted to the United States after inspection and are ineligible to be admitted
legally. Deportable aliens have been inspected and admitted to the United States, but subsequently have become
ineligible to remain and are subject to removal. Those who are physically in the United States but who entered without
inspection, i.e., illegally, are also considered inadmissible. Long-standing legal doctrine, commonly known as the
“entry fiction,” holds that those who are inadmissible have no right to enter or remain in the country, whereas those
who are deportable do have greater protections.
46 Prior to IIRIRA, aliens ineligible to enter the country were “excludable,” rather than “inadmissible,” and were
subject to exclusion proceedings, while deportable aliens were subject to deportation proceedings. After IIRIRA,
exclusion and deportation proceedings were consolidated into removal proceedings, but certain aliens are subject to
expedited removal. The salient difference between excludable and inadmissible aliens is that aliens who entered
without inspection were not considered excludable, whereas such aliens are now considered inadmissible, which means
they are not entitled to the same level of rights in removal proceedings. This change was made as a disincentive to
entering illegally, since formerly, the entry fiction worked in favor of those who entered illegally.

paroled into the United States. If the credible fear is unsubstantiated, the alien is detained until the
alien is removed from the United States.49
Asylum Seekers
As discussed earlier, the Illegal Immigrant Reform and Immigrant Responsibility Act of 1996
(IIRIRA) mandated that aliens who arrive without proper documentation and claim asylum be
detained prior to their “credible fear” hearing. Prior to IIRIRA, most aliens arriving without
proper documentation who applied for asylum were released on their own recognizance into the
United States (and given work authorization), a practice which enabled inadmissable aliens
falsely claiming persecution to enter into the country. Most of the fraudulent claims were made by
people attempting to come here for economic or family reasons, illegally rather than through legal
immigration channels.50 False asylum claims utilize limited resources, causing those with
legitimate claims to have to wait longer to have their cases processed. Thus, many argued that the
only way to deter fraudulent asylum claims was to detain asylum seekers rather than releasing
them on their own recognizance. Indeed some claim that the practice of detaining asylum seekers
has reportedly helped reduced the number of fraudulent asylum claims.51
However, some contend that the policy of detaining all asylum seekers is too harsh. They argue
that there is a need to inhibit fraudulent asylum claims, but mandatory detention of asylum
seekers causes more problems than it solves. The position of the United Nations High
Commission on Refugees is that detention of asylum seekers is “inherently undesirable.”52
Detention may be psychologically damaging to an already fragile population such as those who
are escaping from imprisonment and torture in their countries. Often the asylum seeker does not
understand why they are being detained. Additionally, asylum seekers are often detained with
criminal aliens. Some contend that ICE should develop alternatives to detention (e.g., electronic
monitoring) for asylum seekers.
Release on Parole and Bond
The Secretary has the authority to parole detained aliens who are not subject to mandatory
detention. Most arriving aliens are not eligible for parole. Parole is permitted for arriving aliens
with serious medical conditions, pregnant women, juvenile aliens who will be witnesses, and
“aliens whose continued detention is not in the public interest.”53 In general, parole is available on
a “case-by-case basis for urgent humanitarian reasons or significant public benefit.”54

49 Under the INA, expedited removal can also be applied to aliens who enter the United States without inspection (i.e.,
cross the border without being inspected by an immigration inspector) and cannot establish that they have been
physically present in the United States for more than two years, but it has yet to be applied to those who entered
without inspection. INA §235(b)(1)(A)(iii).

Immigration-Related Detention: Current Legislative Issues

Aliens not subject to mandatory detention may also be released on bonds of a minimum of
$1,500.55 To be released on bond, the alien must prove that he is not a threat to people or property,
and will appear at all future immigration proceedings.
Rights of the Detained
The courts have ruled that detained aliens not under expedited removal56 have the following
rights:
• the right to apply for asylum;
• the right to communicate with consular or diplomatic officers of their home
country;57
• the right to be represented by counsel (but not at government expense);58
• the right to challenge transfers to other detention facilities that might interfere
with the right to counsel;
• the right to medically adequate treatment;
• the right to access free legal service lists and telephones; and
• the right to self-help and other legal reference material.
Under the law, aliens also have the right to legally challenge their detention.59 Custody and bond
determinations can be reviewed by an immigration judge at any time before the removal order
becomes final, except in certain cases.60 Additionally, the alien may appeal the immigration
judges’ decision to the Board of Immigration Appeals (BIA). Nonetheless, the courts have
afforded the Administration much discretion in decisions related to where aliens are detained, the
management of detention facilities, and the treatment of aliens.

55 The IIRIRA raised the minimum bond amount from $500 to $1,500. INA §236(a)(2)(A).
56 As discussed above, those under expedited removal have more limited rights than detainees not subject to expedited
removal.
57 In accordance with U.S. constitutional considerations, customary international law, and the Vienna Convention on
Consular Relations (April 24, 1963, art. 36, T.I.A.S. 6820, 21 U.S.T. 77, to which the United States is a party), the
regulations require notice to detained aliens of their right to communicate with consular and diplomatic officers of their
home country. Additionally, certain countries have treaties with the United States that require notification of the
diplomatic officers of the country when one of their nationals is detained in removal proceedings, regardless of whether
the alien requests such notification and even if the alien requests that no communication be made on his behalf. (8
C.F.R. §236.1(e))
58 Detained aliens have the right to obtain counsel, but since immigration procedures are considered civil, not criminal,
actions, the government is not obligated to provide counsel.

aliens deportable as security threats; (4) criminal aliens; and (5) aliens in pre-IIRIRA deportation proceedings with

Immigration-Related Detention: Current Legislative Issues

Detention Conditions
Although there is consensus that detainees should be treated humanely, there is no consensus on
exactly what the conditions of detention should be.61 In 2000, the former Immigration and
Naturalization Service (INS) created National Detention Standards for aliens in detention, which
are published in the Detention Operations Manual. In late 2008, ICE published new Detention
Standards in a performance-based format. The standards specify the detention conditions
appropriate for immigration detainees.62 In most cases, the standards mirror American
Correctional Association (ACA) standards, though some of ICE’s Detention Standards provide
more specificity or are unique to the needs of alien detainees. The Detention Standards, however,
do not have the force of law, thus detainees do not have legal recourse for violations of the
standards.
Some argue that immigration detention is civil detention and is unlike criminal incapacitation.
They contend that despite the differences, the public views immigration detention as identical to
criminal incarceration, and that the government wrongly manages both confined populations in
the same way.63 They also note that sheer number and type of detention facilities make it difficult
for ICE to ensure that the national detention standards are being followed.64 In 2009, the Obama
Administrated created The Office of Detention Policy and Planning (ODPP) in ICE with the goal
of overhauling the current immigration detention system and “designing a detention system that
meets the unique needs of ICE’s detained population.” According to their website: “ODPP will
shape the future design, location and standards for civil immigration detention facilities so that
ICE no longer relies primarily on existing penal models.”65
Nonetheless, others contend that detained noncitizens should not receive better treatment than
U.S. citizens who are arrested and awaiting trial, noting that aliens are in detention because they

61 For example, some argue that since most detainees do not have criminal records, that they should be housed in low-
security settings, such as converted hotels. Others argue that in a prison system, inmates are only allowed to be in low-
security settings once they have proven that they are not a risk, and that since immigration detention tends to be short-
term, there is not enough time to evaluate which detainees pose a risk to officers and other detainees. Testimonies of

have violated U.S. law.66 In addition, they observe that most noncitizens are only in detention for
a short period of time.67
Detention Statistics
Detention Population
As Figure 1 shows, from FY2001 to 2012, the average size of the daily noncitizen detention
population increased by more than 50%, from 20,429 in FY2001 to 32,953 in FY2012. During
the same time period, the number of funded beds increased from 19,702 to 34,000. The largest
increase in the average daily detention population occurred between FY2006 and FY2007, when
Congress increased bed space funding from 20,800 to 27,500 beds. In addition, except for two
years, between FY2001 and FY2007, the number of funded beds was less than the average daily
detention population. Since FY2008, the number of funded beds has exceeded the average daily
detention population. Nonetheless, it is clear from Figure 1 that the average daily detention
population is closely tied to the amount of funded bedspace.
ICE detained 363,064 aliens during FY2010. During that year, the average daily detention
population was 30,885. Although more than 61% of all detainees were from Mexico, they tended
to have short stays in detention and, thus, they accounted for only 36% of detention bed days. The
other leading countries for the percentage of detention bed days were El Salvador (11%),
Guatemala (10%), and Honduras (8%).68

Detention Space and Cost
Some maintain that DHS detains too many people who are not a threat to public safety and that
the money spent to detain such people could be better spent on other enforcement priorities.69
They argue that the increase in the number of classes of aliens subject to mandatory detention has
impacted the availability of detention space for lower priority detainees and has also affected
ICE’s ability to exercise discretion in determining who to detain or release.70
Others contend that DHS should be detaining more noncitizens to help effectuate removal but
does not have enough detention space to house all those who should be detained. They also argue
that detention is necessary to protect public safety, and to deter illegal border crossers and false
asylum claims.71 There are approximately 480,000 noncitizens in the United States who have
been ordered deported who can not be confirmed to have left the country.72 A study done by
DOJ’s Inspector General found that almost 94% of those detained with final orders of removal
were deported while only 11% of those not detained who were issued final orders of removal left

the country.73 In addition, in 2007, then ICE director John Torres testified that 90% of aliens
released from detention did not appear for their immigration hearings.74
Furthermore, concerns have been raised that decisions on which aliens to release and when to
release the aliens may be based on the amount of detention space, not on the merits of individual
cases. The amount of space varies by area of the country, and may lead to inequities and disparate
policies in different geographic areas.75 In addition, moving detainees between detention
facilities, often relocating them to an area far from where they were arrested, has been shown to
delay hearings and increase the time a person is in detention, which increases detention costs.76
Appropriations for Detention Operations
The overall increase in the number of noncitizens in DHS detention has also focused attention on
cost of detaining noncitizens, especially as Congress tries to balance immigration enforcement
priorities and a tight fiscal budget.77 For FY2011, it cost DHS an average of $113 a day for each
detainee held in detention. This cost does not include transportation or the cost of deporting the
alien, and differs by type of detention facility.78 In comparison, for FY2004, DHS budgeted $80 a
day for each detainee held in detention.79

75 The decision does not usually apply to aliens who are under mandatory detention. A high priority detainee may be
released to make space for a mandatory detainee. Nonetheless, DHS does have explicit procedures for choosing
between two mandatory detainees if there is not enough bed space. Pearson, INS Detention Guidelines, p. 1116. For an

while in all other years money was appropriated for that account. Thus, it is likely that the increase in
appropriations from FY2008 to FY2009 was not as large as it appears, while the decline in appropriations
for ERO from FY2009 to FY2010 was not a real decline, but a difference in accounting. Overall, in FY2009,
ICE received $4.9 billion in appropriations while in FY2010, Congress appropriated $5.3 billion to ICE. For a

As Table 1 shows, funding for ICE’s detention operations increased between FY2008 and
FY2012, even as the fiscal climate has become more constrained. In FY2010 and FY2011,
Congress appropriated similar amounts for custody operations, funding 33,400 beds in both years.
(See Figure 1.) In FY2012, Congress increased the number of beds by 600, and increased
funding for custody operations by $257 million.
Alternatives to Detention
Due to the cost of detaining aliens, and the fact that many non-detained aliens with final orders of
removal do not leave the country, there has been interest in developing alternatives to detention
for certain types of aliens who do not require a secure detention setting. On June 21, 2004, ICE
began a pilot program for low-risk, non-violent offenders in eight locations.80 The program, the
Intensive Supervision Appearance Program (ISAP), provides less restrictive alternatives to
detention, using such tools as electronic monitoring devices (e.g., ankle bracelets), home visits,
work visits, and reporting by telephone, to monitor aliens who are out on bond while awaiting
hearings during removal proceedings or the appeals process.81 The Department of Homeland

80 The locations are San Francisco, California; Denver, Colorado; Miami, Florida; Baltimore, Maryland; St. Paul,
Minnesota; Kansas City, Missouri; Portland, Oregon; and Philadelphia, Pennsylvania. An earlier pilot using Electronic
Monitoring Devices was conducted in Anchorage, Alaska; Miami, Florida; and Detroit, Michigan.

Security Appropriations Act for FY2012 appropriated $72.4 million for alternatives to detention,
including the ISAP.82
Legislation in the 112th Congress
In the 112th Congress, bills have been introduced covering a range of provisions and perspectives
concerning the detention of noncitizens. Several bills—including H.R. 100 and H.R. 1274—
would mandate that DHS increase the amount of detention space. In addition, other bills (e.g.,
H.R. 933, S. 1258) would require the propagation of regulations concerning detainee care, and
expand the alternatives to detention program. Other proposed legislation, such as H.R. 713, would
make changes to the mandatory detention provisions, providing the administration with more
discretion on who should be detained. Only one bill, H.R. 1932, has received any Congressional
action.
On October 18, 2011, the House Judiciary Committee reported the Keep Our Communities Safe
Act of 2011 (H.R. 1932).83 Among other things, H.R. 1932 would codify and modify the
conditions for post-removal order detention. The bill would allow DHS to detain indefinitely,
subject to six-month reviews, an alien under orders of removal who cannot be removed if (1)
there is a significant likelihood that the alien will be removed in the reasonably foreseeable
future; (2) the alien would have been removed but for the alien’s refusal to cooperate with the
DHS Secretary’s identification and removal efforts; (3) the alien has a highly contagious disease
that poses a public safety threat; (4) release would have serious adverse foreign policy
consequences; (5) release would threaten national security; (6) release would threaten the safety
of the community, and the alien has either been convicted of one or more aggravated felonies or
other designated crimes or been convicted of one or more crimes of violence and due to a mental
condition or personality disorder is likely to engage in future acts of violence; or (7) release
would threaten the safety of the community, and the alien has been convicted of at least one
aggravated felony. The bill would limit habeas corpus reviews84 of such detention and related
actions or decisions to the U.S. District Court for the District of Columbia. Also, the bill would
permit unlimited detention of certain aliens during pending removal proceedings.
Proponents of H.R. 1932 contend that legislation is needed to prevent criminal aliens who can not
be removed to their home countries from being released and committing additional crimes.85

Immigration-Related Detention: Current Legislative Issues

They argue that the Supreme Court in Zadvydas v. Davis (2001),86 did not deny Congress the
authority to provide for extended periods of detention. Indeed, they contend that the Court
“invited” Congress to amend existing law to clarify circumstances and procedures under which
extend detention would be permissible.87 Nonetheless, others argue that the criminal justice and
civil commitment systems already exist to keep dangerous individuals away from the public.88
They also contend that H.R. 1932 would allow for the prolonged, unnecessary, and expensive
detention of asylum seekers and other immigrants by preventing bond determination hearings and
limiting habeas corpus review to the U.S. District Court for the District of Columbia.89

86 533 U.S. 678, 121 S. Ct. 2491, 150 L. Ed. 2d 653 (2001). As discussed above, in Zadvydas v. Davis (2001), although
the U.S. Supreme Court held that a statute permitting indefinite detention would raise serious constitutional problems,
the court’s ruling was a matter of statutory interpretation arguing that it was not clear that Congress had meant to
authorize “long-term detention of unremovable aliens.”
