This bill amends existing Washington statutes (RCW 43.17.425, RCW 10.93.160, and RCW 43.10.315) to limit state and local participation in federal immigration registration, surveillance, and civil immigration enforcement. It prohibits state agencies from using agency resources to investigate, enforce, cooperate with, or assist federal programs or laws that target Washington residents solely on the basis of race, religion, immigration or citizenship status, or national or ethnic origin, and requires named agencies to revise policies so they collect only the minimum necessary information, restrict disclosure except as allowed by law, and not condition public services on proof of immigration/citizenship/place of birth. The amendments list specific exceptions (for compliance with other laws or court orders, necessary agency duties unrelated to immigration enforcement, funding requirements, deidentified/aggregated data, and certain statutory provisions). The act changes procedures for law enforcement and custodial practices rather than creating new crimes or altering criminal penalties. It amends RCW 10.93.160 to state legislative findings about federal immigration jurisdiction, bars school resource officers acting in that role from inquiring about or collecting immigration/citizenship/place of birth information or providing such information to federal immigration authorities except as required by law, and permits state and local law enforcement to collect or share immigration-related information only when it is connected to an investigation of state/local criminal law violations or federal civil immigration matters. It prohibits detaining a person solely to determine immigration status, forbids entering into federal civil immigration enforcement contracts (including 8 U.S.C. §1357(g) 287(g) agreements) and immigration detention agreements, and allows the Department of Corrections to permit federal interviews of individuals in custody about immigration matters. The bill imposes implementation timelines and other procedural requirements: specified agencies were to begin implementation within 12 months after May 21, 2019 and demonstrate compliance by December 1, 2021 or December 1, 2023 depending on agency groupings; immigration detention agreements must have been terminated no later than 180 days after May 21, 2019 with a narrow exception for certain pre-2019 agreements; and the attorney general must publish model policies, guidance, and training recommendations within 12 months of July 1, 2026, after which state and local law enforcement must adopt those policies or notify the attorney general they are not adopting them and provide their own. The extracted text omits the chapter number for "chapter . . ., Laws of 2026 (this act)" and does not include the definitions from RCW 43.17.420 referenced by the amendments, so some cross-referenced terms and prior-version edits are not fully present in these facts.

If enacted, covered state agencies (including licensing, labor, employment security, revenue, health agencies, DSHS, DCYF, OSPI, State Patrol and others on a later timetable) will have to tighten what personal information they collect, stop asking for or requiring proof of immigration or citizenship to get services, and revise and publish new policies quickly. School resource officers acting in that role would generally be barred from asking about or turning over immigration or citizenship information except where it clearly connects to a criminal or federal civil immigration investigation, and state and local law enforcement may only share such information or give federal authorities access for interviews when it is tied to an active criminal or federal civil immigration matter. Agencies will also be prohibited from entering 287(g)-type agreements or new immigration detention contracts and must follow deadlines already referenced in the law for terminating older agreements. Practically, the agencies named will face new compliance work, including policy rewrites, training, and publishing final policies, and they must either adopt model policies the attorney general will issue within a year of July 1, 2026, or explain why they did not and provide their own policies. This will change operational duties and could create modest administrative costs for review, training, and documentation while narrowing options for cooperation with federal civil immigration enforcement; however, some specifics are unclear here because the bill text refers to definitions and other statutes not included and omits the chapter citation for the 2026 act, so exact implementation details and how some historical deadlines apply are uncertain.
