C² Technologies partnered with the Office of Fraud Detection and National Security (FDNS), a directorate within the United States Citizenship and Immigration Services (USCIS), to develop quality training for its officers regarding the use of the organization’s Fraud Detection and National Security Data System (FDNS-DS) database. The purpose of this training is to assist field officers who are dealing with national security cases. Participants who take the FDNS-DS Training modules learn how to enter data into the system and link new data to existing data already in the database.
