Immigration and customs laws; prohibiting enactment or adoption of sanctuary city policies; requiring Attorney General to make certain determination upon request; subjecting certain officials to removal from office. Effective date.

Oklahoma's SB 489 prohibits local governments from adopting "sanctuary policies" that restrict cooperation with federal immigration authorities. It specifically bans policies limiting law enforcement from sharing immigration status information, delaying federal immigration holds, or requiring warrants for immigration-related requests. Local governments violating the law lose eligibility for state funding until they repeal the policy, and officials who willfully violate it face removal for misconduct. The bill takes effect November 1, 2025, and directly affects cities, counties, and their officials.
