U.S. Citizenship and Immigration Services Created as a separate bureau by the Homeland Security Act of 2002, USCIS allows the DHS to improve the administration of benefits and immigration services for applicants by exclusively focusing on immigration and citizenship services. This new Bureau includes approximately 18,000 employees and contractors, and is headed by the Director of USCIS, who reports directly to the Deputy Secretary for Homeland Security. http://uscis.gov/graphics/ - More
