On March 1, 2003, services formerly provided by the Immigration and Naturalization Service (INS) transitioned into the Department of Homeland Security (DHS) under U.S. Citizenship & Immigration Services (USCIS). (You can read more about this below.) In support of the DHS overall mission, the priorities of the USCIS are to promote national security, continue to eliminate immigration case backlogs, and improve customer services. The USCIS will continue efforts to fundamentally transform and improve the delivery of immigration and citizenship services. The National Customer Service Center (NCSC) provides nationwide assistance by telephone to customers calling from within the United States about immigration services and benefits. Service is available in English and Spanish.
