U.S. Citizen and Immigration Services

What is the U.S. Citizenship and Immigration Services (USCIS)?

The USCIS enforces laws providing for selective immigration and controls entry of tourists, business travelers, and other temporary visitors. It does so by inspecting and admitting arrivals at land, sea, and air ports of entry, administering benefits such as naturalization and permanent resident status, and apprehending and removing aliens who enter illegally or violate the requirements of their stay.

Visit the U.S. Citizenship and Immigration Services' website for complete information on the agency.
