Attention, huddled masses, the line forms here. US Citizen and Immigration Services (USCIS) is responsible for the administration of immigration and naturalization adjudication functions and the establishment of immigration services policies and priorities. USCIS administers family- and employment- based petitions, naturalization services, and asylum and refugee processing. Part of the Department of Homeland Security, USCIS took over the service and benefit functions of the Immigration and Naturalization Service (INS) in 2003 after a restructuring shifted various INS functions to separate bureaus including the USCIS, US Immigration and Customs Enforcement (ICE), and US Customs and Border Protection (CBP).

USCIS's employs some 18,000 workers at 250 offices around the world. The US government has immigration and citizenship laws that date back to the 1790s.

Alejandro Mayorkas, formerly the US attorney for the central district of California, was named the director of USCIS in 2009. He replaced Emilio Gonzalez, who resigned after two years in the post.
