The main purpose of this legislation is to ensure that only U.S. citizens can be hired to administer elections for federal offices at the state or local level. The objective is to enhance the integrity and security of the electoral process by restricting election administration roles to individuals who are citizens of the United States. The key provision of this law states that no state or local government can employ non-citizens to manage or oversee elections for federal positions. This requirement applies to all elections for federal office that take place after the law is enacted.
