DHS/CISOMB/PIA-001 – Ombudsman Case Assistance Analytic Data Integration System


The U.S. Department of Homeland Security (DHS), Office of the Citizenship and Immigration Services Ombudsman (CISOMB) as mandated by Section 452 of the Homeland Security Act of 2002, is an independent office that reports directly to the Deputy Secretary of Homeland Security. CISOMB’s mission is to: (1) assist individuals and employers who are experiencing difficulty resolving immigration benefit-related matters with U.S. Citizenship and Immigration Services (USCIS); (2) identify systemic challenges or trends with the delivery of immigration benefits; and (3) propose changes to mitigate those issues pursuant to 6 U.S.C. § 272(b). To accomplish this mission, CISOMB uses the Case Assistance Analytics and Data Integration (CAADI) system to process, track, and respond to requests for assistance, and to manage the workflow of cases. CISOMB is conducting this PIA to discuss the information that CISOMB receives from individuals and employers and processes through CAADI. This PIA updates and replaces the 2010 DHS/CISOMB/PIA-001 Virtual Ombudsman System PIA.
