Wyoming has become the first state to enact a law requiring proof of citizenship in all elections, including federal.

The bill was passed by the state legislature and became law without the governor's signature.

"I'm pleased to announce that the Governor has allowed proof of citizenship and proof of residency for registering to vote to become law without his signature," Wyoming Secretary of State Chuck Gray (R) posted on X on Friday. "This was the #1 priority of our conservative election integrity reform agenda. With HB156 becoming law, Wyoming will further advance election integrity, as the only state in the nation to require proof of citizenship for all elections, an important priority of President Trump."

The law, House Bill 156, requires voters to provide proof of citizenship and Wyoming residency, in addition to instituting a requirement to reside in the state for a period of time before being eligible to register to vote. Other states that require proof of citizenship for voters do not apply the requirement to federal elections.

"Today marks a pivotal moment for election integrity in Wyoming," Gray said in a statement. "Proof of citizenship and proof of residency for registering to vote are both so important. Only United States citizens, and only Wyomingites, should be voting in Wyoming elections. Period.

"HB 156 makes Wyoming the first state in the nation to apply proof of citizenship for registering to vote for all elections," he continued. "This was the first priority of our conservative election integrity reform agenda. It will ensure that we protect Wyoming elections, and is also key in supporting President Trump’s pivotal work to have proof of citizenship for registering to vote with the SAVE Act at the federal level. I am thrilled that the priorities of the people of Wyoming have won out."

Wyoming Gov. Mark Gordon (R) wrote in a letter to Gray that while he believed the bill to be somewhat redundant and contradictory of some statutes, he would allow it to become law as it granted the secretary of state "rulemaking authority … with regard to forms of identification to be used to prove Wyoming residency and United States citizenship."
