End Sanctuary Cities Act of 2026

S 3805, the End Sanctuary Cities Act of 2026, requires state and local government officials to provide "reasonable advance notice" to federal immigration authorities about the release of non-citizens convicted of crimes. It specifically prohibits officials from blocking such notice through policies or actions, targeting jurisdictions that limit cooperation with federal immigration enforcement. Violations carry criminal penalties: up to 25 years in prison for releases involving murder, rape, or sex offenses against minors, 5-10 years for serious violent felonies, and 30 days-6 months for other crimes. The bill directly affects state and local law enforcement officials who implement policies restricting immigration cooperation. It does not change existing immigration laws but adds penalties for obstructing their enforcement.
