In recent months, Congress has expressed concern that some foreign fighters might exploit the Visa
Waiver Program (VWP) to enter the United States and commit acts of terrorism. The VWP allows
eligible visitors from 38 European nations and a few prosperous Asia-Pacific countries (Figure 1) to
enter the United States for short business or leisure stays without first obtaining a visa from a U.S.
consulate abroad. Recent attacks by domestic terrorists in Europe and reports of European countries'
citizens fighting with armed groups in the Middle East have raised concerns that potential terrorists
could travel to the United States with little scrutiny under the VWP.
Balancing national security interests against efforts to facilitate international travel through the VWP
presents challenges to legislators. The United States has a large travel and tourism industry. In 2013,
travel and tourism accounted for 2.6% of U.S. gross domestic product and directly employed nearly 5.4
million Americans. Foreign visitors in the United States account for a disproportionate amount of U.S.
travel and tourism spending. International travelers spent about $215 billion in 2013 on passenger fares
and travel-related goods and services, which makes tourism the United States' single-largest services
sector export.

An average foreign visitor spends about $4,500 domestically on travel activities, which outpaces
domestic visitor spending, based on estimates by the U.S. Travel Association (U.S. Travel). Competition
for the world's tourists is fierce, however. A record 70 million foreign visitors traveled to the United
States in 2013, yet the U.S. share of long-haul travel declined to 13.2% in 2013 from 17.1% in 2000,
according to U.S. Travel. The Obama Administration has set a goal of increasing the annual number of
international visitors to 100 million by the end of 2021. Travel industry interests have advocated
expanding the visa waiver program to additional countries as a way to stimulate tourism.
Visa Waivers and Security
Before traveling to the United States, a VWP traveler must submit biographical information through the
Department of Homeland Security's web-based Electronic System for Travel Authorization (ESTA)
application, which determines the eligibility of the foreign national to enter under the VWP. Notably,
even with a valid ESTA approval the foreign national may still be deemed inadmissible and denied entry
by Customs and Border Protection (CBP) inspectors upon arrival at a U.S. port of entry.
About 20 million people arrived in the United States under the VWP in FY2013 (Figure 2), representing
more than one-third of all temporary visitors. In 2013, according to U.S. Travel, VWP visitors spent $79
billion while traveling to and within the United States. Recently, the Partnership for a New American
Economy, a business group, estimated that if the United States added Brazil, Hong Kong, Turkey,
Israel, South Africa, and Poland to the VWP, the number of foreign travelers from these countries
would increase by 1.7 million, add $7.7 billion in tourism spending, and support at least 50,000
American tourism jobs over the period from 2015 to 2019.

Security (DHS) admitted 10 new countries into the program.
Another country, Chile, was added in FY2014.
While there tends to be agreement that the VWP benefits the U.S. economy by facilitating legitimate
travel, there is disagreement on the VWP's impact on national security.
Proponents say the VWP strengthens U.S. national security because it sets standards for travel
documents, requires information sharing between the member countries and the United States on

criminal and security concerns, and mandates reporting of lost and stolen travel documents. In
addition, VWP travelers have to present machine-readable passports or e-passports, and eventually all
travelers entering under the VWP will present e-passports, which tend to be more difficult to alter than
other types of passports.
Critics argue the VWP could create a security loophole because VWP travelers do not undergo the
screening traditionally required to receive a visa. For example, European passport holders who have
joined the terrorist group known as the Islamic State (also referred to as ISIS or ISIL) could use it to
try to enter the United States without the security checks that holders of other countries' passports
undergo when applying for a visa. European governments estimate that more than 2,000 European
Union citizens have traveled to Syria, including hundreds from Great Britain, France, and Germany.
While ESTA has increased the security of the VWP, it is a name-based system and cannot be used to
run checks against databases that use biometrics such as DHS's Automated Biometric Identification
System (IDENT) and the Federal Bureau of Investigation's (FBI's) Integrated Automated Fingerprint
Identification System (IAFIS).
Congressional Interest
The Visa Waiver Program Improvement Act of 2015 (H.R. 158), introduced by Representative Candice
Miller, would allow the Secretary of the Department of Homeland Security to immediately suspend a
country's participation in the VWP if the country fails to provide the United States with pertinent
traveler information related to security threats. In the 114th Congress, no bills have been introduced to
expand the VWP program to new participants. Several bills in 113th Congress would have changed the
eligibility criteria so that countries such as Poland and Hong Kong would have qualified. Other
introduced bills would have suspended the VWP.
