Overlaid on a dark teal gradient, the graphic showcases a corporate team analyzing regional regulatory adjustments in a bright office environment. A senior female executive with silver hair points her pen at a clipboard document labeled "LEGISLATION," which displays an official circular seal and a legal stamp. Her diverse colleagues sit at the desk reviewing data sheets and open laptops with financial charts, visually highlighting the strategic collaboration and careful scrutiny required to align corporate operations with changing state statutes.

Washington employers must display a new workplace poster under the state’s Immigrant Worker Protection Act.

The state Attorney General’s Office released the poster, along with model employee notices and employer guidance, on Sept. 1, 2026, ahead of the law’s Oct. 1, 2026, effective date.

The AGO provides two separate notices: One for the I-9 inspection event itself, which must be posted where all workers can see it, and one for affected employees. All materials are available in English, Mandarin, Russian, Spanish, Ukrainian and Vietnamese.

Under the law, employers must inform workers within five business days after receiving a federal notice of inspection of workers’ employment-eligibility documents, including Form I-9s.
