Missouri RSMo 67.307 forbids any municipality from adopting sanctuary policies, requiring local officials to cooperate with federal immigration authorities and barring restrictions on information-sharing about immigration status.
RSMo 67.307 prohibits Missouri political subdivisions from enacting any sanctuary policy that limits or restricts the enforcement of federal immigration law or otherwise impedes communication between local officials and U.S. Immigration and Customs Enforcement. Cities, counties, and law enforcement agencies cannot prohibit officials from inquiring about immigration status, sharing such information with federal authorities, or honoring detainer requests where lawfully issued. Municipalities found in violation are ineligible to receive state grant funds until the policy is rescinded. The statute works alongside RSMo 285.530, which addresses E-Verify obligations, to create a uniform anti-sanctuary regime statewide. Local officials remain bound by federal constitutional limits on detentions, but Missouri law removes any local discretion to formally adopt sanctuary status.
A municipality that adopts or maintains a sanctuary policy loses eligibility for state grant funds under RSMo 67.307. Officials who direct noncompliance may face administrative discipline, and the attorney general may seek declaratory or injunctive relief.
