      The Department of Homeland Security (DHS) plays a central role in administering the immigration system of the United States.

      Administration of immigration benefits is the responsibility of U.S. Citizenship and Immigration Services (USCIS).

      In order to have a liaison between the public and DHS on immigration benefits matters, Congress created the Citizenship and Immigration Services Ombudsman, which operates independently from USCIS.
