Relating to a person submitting proof of citizenship to verify eligibility to vote in Texas.

SB 309 requires voters in Texas to submit proof of citizenship when registering to vote. It directly affects all individuals registering to vote in Texas by adding a new requirement to verify eligibility. The bill mandates the secretary of state to request federal changes to voter registration forms by January 1, 2026, to include citizenship proof, and if federal authorities refuse, the attorney general must seek court enforcement. Registrars must then require this proof under new rules, effective September 1, 2025. The bill does not change voting procedures for those already registered.
