INS

(US GOVERNMENT) Immigration and Naturalization Service: former agency of the US government responsible for the enforcement of immigration law, and the processing of visa/permit requests. The INS and its successor (see below) are justly famous for treating millions of hardworking, intelligent, and creative people with the most demeaning, barbaric sort of bureaucratic cruelty imaginable. After the attacks of 11 September 2001, Congress passed a bill creating the Department of Homeland Security (DHS); the INS was split up into its enforcement functions (which became part of Immigration and Customs Enforcement (ICE) and its processing functions (Citizenship and Immigration Services, or CIS). Prior to its dissolution in 2003, the INS was part of the Department of Justice. The CIS and ICE are both part of the DHS.
