Modifies provisions relating to employment of unauthorized aliens

HB 2511 requires state contractors, public employers, and businesses receiving state contracts or subsidies to verify employees' work authorization through a federal program (like E-Verify) and submit annual sworn affidavits confirming they do not knowingly employ unauthorized immigrants. It mandates that the state attorney general enforce these rules by investigating complaints, verifying immigration status via federal data, and suspending business licenses for violations after court findings. The law suspends verification requirements for 15 days during declared emergencies like natural disasters. This directly affects businesses working with Missouri state or local government, requiring them to implement new compliance procedures for employee eligibility.
