The government entity that administers immigration and naturalization adjudication functions is the United States Citizenship and Immigration Services (USCIS). USCIS, part of the Department of Homeland Security, handles the processing and adjudication of immigration benefits—such as naturalization, green cards, and related petitions—and implements DHS-directed policy through these decisions. The other options don’t refer to an agency responsible for these functions: an L-1 visa is a specific intracompany transferee visa category, freedom of movement is a general civil liberty concept, and an expatriate ghetto is not a formal government term.
