From the "Message from the Ombudsman": "I am pleased to present to you the Ombudsman's 2018 Annual Report to Congress. This report is required by Section 452 of the Homeland Security Act of 2002, which established the Office of the Citizenship and Immigration Services Ombudsman. It also charged us with the responsibility of helping applicants and employers solve difficulties encountered when applying for immigration benefits and working to improve systemic problems in the delivery of immigration services. The year 2017 was one of significant change in immigration policy. Inaugurated in January, President Trump quickly signed multiple immigration-related executive orders for the purpose of ensuring that the nation's immigration laws are faithfully executed. Immediately, the various immigration agencies within the Department of Homeland Security--including Customs and Border Protection, Immigration and Customs Enforcement, and U.S. Citizenship and Immigration Services (USCIS)--set out to execute those orders through draft regulations, new policy guidance, and revised processes."
