United States Citizenship and Immigration Services Authorization Act This bill amends the Homeland Security Act of 2002 to: (1) establish, by statute, U.S. Citizenship and Immigration Services within the Department of Homeland Security, and (2) and remove references to the Bureau of Citizenship and Immigration Services. The Illegal Immigration Reform and Immigrant Responsibility Act of 1996 is amended to make E-Verify, which allows employers to verify an employee's work eligibility, permanent. The bill maintains the application fee for an intercountry adopted child at the amount that was in effect effect prior to the effective date (i.e., 12/23/2016) of the rule increasing such fee.
