Congress has expressed interest in the visa categories by which foreign nationals may enter or be present in the United States. U.S. immigration policy is governed largely by the Immigration and Nationality Act (INA), which was first codified in 1952 and has been amended significantly several times since.1 The United States has long distinguished permanent immigration from temporary immigration. Permanent immigration occurs through family and employer-sponsored categories, the diversity immigrant visa lottery, and refugee and asylee admissions. Temporary immigration occurs through the admission of visitors for specific purposes and limited periods of time, and encompasses two dozen categories (which are commonly referred to by the letter and numeral that denote their subparagraph in the INA).2
This brief report provides the following information:
This information is provided in two tables: Table 1 contains information for nonimmigrant visa categories, and Table 2 contains information for LPR categories.

FY2017 Recipients: U.S. Department of Homeland Security, Yearbook of Immigration Statistics FY2017, Table 6.
a. Categories in which the number of LPR recipients exceeds the statutory annual numeric limit are largely due to timing differences between when LPR status is officially granted, and when immigrants actually arrive in the United States and are counted by DHS as green card recipients. These differences also result from the "roll-downs" of unused visa numbers from higher-priority categories. For more information, see Table 1 in CRS Report R42866, Permanent Legal Immigration to the United States: Policy Overview.
b. The Immigration and Nationality Act provides 40,040 EB-3 immigrant visas each year. However, beginning in FY2002 that annual ceiling has been reduced by up to 5,000 each year to accommodate adjustments made under the Nicaraguan and Central American Relief Act (NACARA, Title II of P.L. 105-100). The 5,000 offset is temporary, but it is unclear for how many years it will remain in effect to handle these adjustments of status.
c. The Immigration and Nationality Act provides 55,000 diversity immigrant visas each year. However, beginning in FY1999 that annual ceiling has been reduced by up to 5,000 each year to accommodate adjustments made under the Nicaraguan and Central American Relief Act (NACARA, Title II of P.L. 105-100). The 5,000 offset is temporary, but it is unclear for how many years it will remain in effect to handle these adjustments of status.
