Difference Between INS and USCIS?
 

Although many people still use the name Immigration and Naturalization Service (INS) to refer to the current agency, this is not correct. The INS no longer exists. U.S. Citizenship and Immigration Services (USCIS) is the current name of the agency that administers immigration and naturalization services in the U.S.

On March 1, 2003, after the Homeland Security Act of 2002 came into law, former INS functions were placed under three agencies within the newly-created Department of Homeland Security: USCIS, Immigration and Customs Enforcement (ICE), and Customs and Border Patrol (CBP).
