Wyoming became the first state in the country last week to require proof of citizenship to vote in all elections.
“On March 21, 2025, House Bill 156 was allowed to become law without the governor’s signature. House Bill 156 requires proof of United States citizenship and proof of Wyoming residency to register to vote in Wyoming, as well as institutes a durational residency requirement,” Wyoming Secretary of State Chuck Gray’s office announced.
The bill also requires a 30-day state residency requirement in order to vote.
“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. 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,” he continued. “I am thrilled that the priorities of the people of Wyoming have won out. I appreciate the work of Representative John Bear and the Wyoming Freedom Caucus on this important issue. With HB 156 becoming law, Wyoming will further cement our commitment to election integrity, as the only state to require proof of citizenship for all elections, an important priority of President Trump.”
The law takes effect on July 1, 2025.
Wyoming Governor Mark Gordon (R) explained in a letter to Gray that he could not sign the bill because it “adheres to neither the original construction of our Constitution nor federal law in its durational requirement.”
