Requiring verification of citizenship for voter registration.

HB 1585 requires Washington counties to verify that registered voters have proof of U.S. citizenship by July 1, 2025. It directs county election offices to check if voters have submitted acceptable documentation (like a passport, naturalization certificate, or specific certified U.S. birth certificate) and to send notices if they lack it. Voters without proof face registration cancellation 14 days before the 2025 general election unless they provide documentation. The law expires January 1, 2027, and explicitly rejects birth certificates from Puerto Rico issued before July 2010 and Washington wallet-sized birth registrations as valid proof.
