The proposed bill, known as the Immigrant Worker Protection Act, aims to enhance protections for immigrant workers in Washington State by establishing new requirements for employers regarding federal I-9 audits. It mandates that employers notify affected workers and their authorized representatives within 72 hours of receiving notice of an I-9 inspection. Employers must post a notice about worker rights in multiple languages and provide written notifications detailing the inspection results and any deficiencies identified. The bill also prohibits employers from interfering with workers' rights and outlines penalties for violations, which can escalate based on the number of workers employed by the employer at the time of the violation.

Additionally, the bill clarifies that employers are not required to conduct self-audits of I-9 forms and establishes that any voluntary consent to federal agencies accessing worker records must be accompanied by a subpoena or judicial warrant. The Attorney General is tasked with developing guidance for employers and enforcing the provisions of the act, which includes the ability to investigate complaints and impose penalties for non-compliance. The act is designed to protect immigrant workers' rights, promote clarity for employers, and ensure that immigrant contributions to the state's economy are recognized and safeguarded.
