Modifies provisions relating to employment and creates new requirements relating to the verification of the immigration status of certain persons

HB 120 prohibits Missouri municipalities from adopting "sanctuary policies" that limit cooperation with federal immigration authorities, making such jurisdictions ineligible for state grants until repealed. It requires all employers (public and private) to verify employees' work authorization through a federal program and submit annual sworn affidavits confirming no unauthorized workers are employed. Employers failing to comply face penalties including license suspensions by state agencies, with enforcement initiated via written complaints to the attorney general. The bill excludes qualified immigrant workers registered in Missouri’s labor database from certain verification requirements. This legislation directly affects local governments and businesses statewide, imposing new compliance obligations under federal immigration verification standards.
