USCIS Responses to Annual Reports to Congress
By statute, the Office of the Citizenship and Immigration Services Ombudsman submits an Annual Report to Congress by June 30 of each year. The Ombudsman’s Annual Report must provide a summary of the most pervasive and serious problems encountered by individuals and employers applying for immigration benefits with U.S. Citizenship and Immigration Services (USCIS). The Annual Report also reviews past recommendations to improve USCIS programs and services.
