Description: Typically, the annual number of refugees that can be admitted into the United States, known as the refugee ceiling, and the allocation of these numbers by region are set by the President after consultation with Congress at the start of each fiscal year. For FY2012, the worldwide refugee ceiling is 76,000, with 73,000 admissions numbers allocated among the regions of the world and 3,000 numbers comprising an unallocated reserve. Overseas processing of refugees is conducted through a system of three priorities for admission. Priority 1 comprises cases involving persons facing compelling security concerns. Priority 2 comprises cases involving persons from specific groups of special humanitarian concern to the United States (e.g., Iranian religious minorities). Priority 3 comprises family reunification cases involving close relatives of persons admitted as refugees or granted asylum. Special legislative provisions facilitate relief for certain refugee groups.

Description: U.S. employers in various industries argue that they need to hire foreign workers to perform lower-skilled jobs, while others maintain that many of these positions could be filled by U.S. workers. While the discussion of current guest worker programs in this report focuses on the H-2A and H- 2B visas, it also covers the Summer Work Travel (SWT) program, the largest of several programs under the J-1 visa for participants in work- and study-based exchange visitor programs. The SWT program is particularly relevant because participants work largely in unskilled jobs, including H-2B-like seasonal jobs at resorts and amusement parks.

Description: When civil unrest, violence, or natural disasters erupt in spots around the world, concerns arise over the safety of foreign nationals residing in the United States who are from these troubled places. Provisions exist in the Immigration and Nationality Act (INA) to offer temporary protected status (TPS) or relief from removal under specified circumstances. A foreign national who is granted TPS receives a registration document and an employment authorization for the duration of TPS. The United States currently provides TPS or deferred enforced departure (DED) to over 300,000 foreign nationals from a total of eight countries: El Salvador, Haiti, Honduras, Nicaragua, Somalia, Sudan, and most recently Southern Sudan and Syria.

Description: Congress is renewing its interest in facilitating the immigration of foreign professional workers in science, technology, engineering, or mathematics (STEM) fields. The STEM workforce is seen by many as a catalyst of U.S. global economic competitiveness and is likewise considered a key element of the legislative options aimed at stimulating economic growth. "STEM visa" is a shorthand for an expedited immigration avenue that enables foreign nationals with graduate degrees in STEM fields to adjust their immigration status to legal permanent residence (LPR) without waiting in the queue of numerically-limited LPR visas.

Description: History and geography have given Mexico a unique status in the U.S. immigration system, and have made the Mexico-U.S. migration flow the largest in the world. Mexicans are the largest group of U.S. migrants across most types of immigration statuses—a fact that may have important implications for how Congress makes U.S. immigration policy. This report reviews the history of immigration policy and migration flows between the countries and the demographics of Mexicans within the United States. It also analyzes contemporary issues in U.S. immigration policy and the impact Mexico may have on U.S. immigration outcomes.
