The INS or the Immigration and Naturalization Service was a US government agency that dealt with immigration and naturalization processes until 2003. However, the agency was dissolved and its functions were transferred to the Department of Homeland Security. Therefore, when referring to the INS, it is important to use the correct terminology. Some synonyms for the INS include US Citizenship and Immigration Services (USCIS), Border Patrol, Immigration and Customs Enforcement (ICE), and Customs and Border Protection (CBP). Each of these agencies plays an important role in managing immigration processes and ensuring the safety and security of the United States.
