HB 312 adds Section 601.012 to the Texas Government Code, requiring U.S. citizenship as a qualification for appointment to public office or service on advisory boards or task forces at all levels of state government and political subdivisions. This requirement excludes positions where the Texas or U.S. Constitution prescribes exclusive qualification criteria. The bill stipulates that individuals currently holding such positions without U.S. citizenship will have their terms end by September 1, 2025, unless they become citizens by that date.
