All 49 states with voter registration systems (North Dakota does not have a voter registration system) require applicants to declare that they are U.S. citizens in order to register to vote in state and federal elections, under penalty of perjury or other punishment. Seven states — Alabama, Arizona, Georgia, Kansas, Louisiana, New Hampshire, and Wyoming — have laws requiring proof of citizenship at the time of voter registration. Court decisions invalidated Kansas' proof of citizenship law, and Alabama, Georgia, and Louisiana have not implemented the requirements of their proof of citizenship laws.

In 1996, the U.S. Congress passed a law prohibiting noncitizens from voting in federal elections, including elections for the U.S. House, U.S. Senate, and presidential elections. This law does not apply to elections for state and local offices. Click here for more information about laws permitting noncitizens to vote in the United States.

This article covers state laws requiring proof of citizenship for voter registration in the United States. It includes details about state laws requiring proof of citizenship and language from federal law.

HIGHLIGHTS

As of June 2025:

Seven states — Alabama, Arizona, Georgia, Kansas, Louisiana, New Hampshire, and Wyoming — have passed laws requiring proof of citizenship to register to vote.

While laws in six of those states require new registrants to provide proof of citizenship when registering to vote, in one state — Wyoming — the law requires both new registrants and those updating their voter registration to provide proof of citizenship.

A federal court blocked Kansas' proof of citizenship law in 2018, and Alabama, Georgia, and Louisiana have not implemented their proof of citizenship requirements.

The other 42 states with voter registration systems require applicants to declare that they are U.S. citizens in order to register to vote in state and federal elections.

Proof of citizenship requirements in the United States

The map below indicates which U.S. states have laws requiring proof of citizenship to vote, including those in effect as of June 2025.

State laws requiring proof of citizenship

Alabama

An Alabama state law, passed in 2011, requires people to provide proof of U.S. citizenship when registering to vote. However, as of June 2025, the law had not been implemented.

In 2013, the U.S. Supreme Court ruled that states cannot require proof of citizenship with federal registration forms. That meant states would need to create a separate registration system for state elections in order to require proof of citizenship. Alabama Secretary of State John Merrill (R) said the following: "That’s an election administration nightmare ... You’d have to have two sets of poll books, one for federal elections and one for state elections, and that just doesn’t make any sense to me."

An individual applying to register to vote must attest that they are a U.S. citizen under penalty of perjury.

Arizona

Arizona requires voters to submit proof of citizenship with their voter registration application to vote in state and local elections. According to the Arizona Secretary of State's website: "A registrant who attests to being a citizen but fails to provide proof of citizenship and whose citizenship is not otherwise verified will be eligible to vote only in federal elections (known as being a 'federal only' voter)." Accepted proof of citizenship include:

• An Arizona Driver's License/Identification Number
• Indian Census Number, Bureau of Indian Affairs Card Number, Tribal Treaty Card Number, or Tribal Enrollment Number
• A photocopy of U.S. naturalization documents
• A photocopy of a birth certificate and supporting legal documentation (i.e., marriage certificate) if the name on the birth certificate is not the same as your current legal name.
• A photocopy of a U.S. passport.
• A photocopy of a Tribal Certificate of Indian Blood or Bureau of Indian Affairs Affidavit of Birth.

On August 22, 2024, the U.S. Supreme Court issued an emergency order partially granting the Republican National Committee and Arizona Republicans' request to enforce a 2022 law related to proof of citizenship requirements. The court allowed the enforcement of the provision requiring the state to reject state voter registration forms submitted without proof of citizenship. Previously, a person who submitted a state voter registration form without proof of citizenship could still be a federal only voter. After the court's ruling, a person unable to provide proof of citizenship would need to submit a federal voter registration form in order to vote in federal elections.

Georgia

A Georgia state law, passed in 2009, required voters to provide proof of U.S. citizenship when registering to vote. However, as of June 2025, the law had not been implemented.

In 2013, the U.S. Supreme Court ruled that states cannot require proof of citizenship with federal registration forms. That meant states would need to create a separate registration system for state elections in order to require proof of citizenship.

In Georgia, an individual must attest that they are a U.S. citizen when registering to vote. According to the state's voter registration application, a voter who provides false information on a voter registration application is guilty of a felony.

Kansas

A Kansas state law that went into effect in 2013 required voters to provide proof of U.S. citizenship when registering to vote. However, the provision was challenged in court and on June 18, 2018, Judge Julie Robinson, of the United States District Court for the District of Kansas, struck down the proof of citizenship requirement and ordered Secretary of State Kris Kobach (R) to stop enforcing the rule. On June 20, 2018, Kobach’s office advised county clerks to comply with Robinson’s order. Kobach appealed the decision to the United States Court of Appeals for the Tenth Circuit, which heard oral arguments on March 18, 2019. On April 29, 2020, a Tenth Circuit panel affirmed the district court's ruling.

Louisiana

Louisiana state law requires a voter registration applicant to provide proof of citizenship to register to vote. As of June 2025, the state had not implemented the requirement.

New Hampshire

New Hampshire requires voters to provide proof of citizenship when registering to vote, as of June 2025. Gov. Chris Sununu (R) signed HB 1569 into law on September 17, 2024. The legislation required voter registration applicants to provide one of the following at the time of registration: "birth certificate, passport, naturalization papers if the applicant is a naturalized citizen, or any other reasonable documentation which indicates the applicant is a United States citizen."

Wyoming

Wyoming requires voters to provide proof of citizenship. Eligible documents are state and tribal IDs that do not indicate the individual is not a U.S. citizen, passports, certificates of citizenship or naturalization, a selective service registration acknowledgement card, documentation of a birth abroad issued by the State Department, or an original or certified copy of a birth certificate.

Federal law on voting and citizenship

Federal law states that it is unlawful for a noncitizen to vote in federal elections and establishes the punishment of a fine, one year in prison, or both for violation of the law. The Illegal Immigration Reform and Immigrant Responsibility Act of 1996 states the following:

“

(a) It shall be unlawful for any alien to vote in any election held solely or in part for the purpose of electing a candidate for the office of President, Vice President, Presidential elector, Member of the Senate, Member of the House of Representatives, Delegate from the District of Columbia, or Resident Commissioner, unless— (1) the election is held partly for some other purpose; (2) aliens are authorized to vote for such other purpose under a State constitution or statute or a local ordinance; and (3) voting for such other purpose is conducted independently of voting for a candidate for such Federal offices, in such a manner that an alien has the opportunity to vote for such other purpose, but not an opportunity to vote for a candidate for any one or more of such Federal offices. (b) Any person who violates this section shall be fined under this title, imprisoned not more than one year, or both.

”

The law includes the following exceptions:

“

(c) Subsection (a) does not apply to an alien if— (1) each natural parent of the alien (or, in the case of an adopted alien, each adoptive parent of the alien) is or was a citizen (whether by birth or naturalization); (2) the alien permanently resided in the United States prior to attaining the age of 16; and (3) the alien reasonably believed at the time of voting in violation of such subsection that he or she was a citizen of the United States.

”

Federal law also states that noncitizens who violate the law are inadmissible (ineligible to receive visas and ineligible to be admitted to the U.S.) and deportable.
