USCIS created the Office of Fraud Detection and National Security (FDNS) in 2004 with a mission to detect, deter, and combat immigration benefit fraud and to strengthen USCIS’ efforts ensuring benefits are not granted to persons who threaten national security or public safety. FDNS is USCIS’ primary conduit for information sharing and collaboration with other governmental agencies, including Immigration Customs and Enforcement (ICE). FDNS employs Immigration Officers, Intelligence Research Specialists, and Analysts located in field offices throughout the United States. Additionally, FDNS has contracted with multiple private investigation firms to conduct site visits on behalf of FDNS. FDNS’ budget is derived from the Fraud Prevention Fee, which is paid by employers with each initial H-1B or L-1 petition.
