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.

SB 489 prohibits Oklahoma local governments from adopting "sanctuary policies" that limit cooperation with federal immigration authorities. It bans ordinances restricting law enforcement from sharing immigration status information, complying with federal detainers, or asking about immigration status when probable cause exists. Local governments violating this lose state funding until the policy changes, and officials who willfully violate it face removal from office. The bill takes effect November 1, 2025, and applies to all cities, counties, and local agencies within Oklahoma.
