DHS/USCIS/PIA-031 Citizenship & Immigration Data Repository


The Department of Homeland Security (DHS), U.S. Citizenship and Immigration Services (USCIS) developed the Citizenship and Immigration Data Repository (CIDR) to enable authorized USCIS users to efficiently query multiple USCIS benefits administration systems from a single entry point. CIDR allows for the vetting of USCIS immigration request information for indications of possible immigration fraud and national security concerns, detecting possible fraud and misuse of immigration information or position by USCIS employees for personal gain or by coercion, and responding to requests for information (RFI) from the Department of Homeland Security (DHS) Office of Intelligence and Analysis (I&A) or the federal intelligence community (IC) and law enforcement community (LE) members that are based on classified criteria. USCIS is updating this Privacy Impact Assessment (PIA) to (1) document a change in CIDR’s data sources and (2) redefine the Office of Security and Integrity’s (OSI) use of CIDR.
