The "New Hampshire UOCAVA Voter Citizenship Verification Act of 2026" mandates that certain overseas voters, specifically those voting under the Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA), must provide proof of U.S. citizenship to register or maintain their voter registration in New Hampshire. This requirement will take effect on January 1, 2027, and applies to all UOCAVA voters except military members and their families, who are exempt from this requirement. Acceptable forms of proof include a U.S. passport, birth certificate, Certificate of Citizenship, or Naturalization Certificate, among others. The Secretary of State will establish a secure portal for electronic submissions and will verify the submitted documents.

Additionally, the bill outlines the responsibilities of the Secretary of State in notifying registered non-exempt UOCAVA voters about the new requirement and providing educational resources to facilitate compliance. It emphasizes that no non-exempt UOCAVA voter will be allowed to cast a ballot after January 1, 2027, unless their proof of citizenship has been verified. The act also includes provisions for rulemaking to implement the new requirements and ensures compliance with federal laws to protect the voting rights of UOCAVA voters.
