U.S. Immigration and Naturalization Service (INS)

The U.S. Immigration and Naturalization Service (INS) was a federal agency responsible for managing immigration and citizenship processes in the United States. Established in 1933, the INS oversaw the admission of immigrants, the naturalization of citizens, and the enforcement of immigration laws. In 2003, it was dissolved and its functions were transferred to the Department of Homeland Security, leading to the creation of U.S. Citizenship and Immigration Services (USCIS) for citizenship and immigration services, and U.S. Immigration and Customs Enforcement (ICE) for enforcement and investigation duties. The INS played a crucial role in shaping U.S. immigration policy.
