The Safeguard American Voter Eligibility (SAVE) Act proposes significant amendments to the National Voter Registration Act of 1993 (NVRA), primarily by mandating that individuals provide documentary proof of United States citizenship to register to vote in federal elections. This legislation aims to ensure that only eligible citizens are enrolled on voter rolls by prohibiting states from accepting registration applications without such proof. The bill provides a detailed list of acceptable documents, including valid U.S. passports, REAL ID-compliant identification, and certified birth certificates when presented with other government-issued photo identification. Under the Act, states would be required to establish ongoing programs to identify and remove non-citizens from voter rolls, utilizing data from federal agencies such as the Department of Homeland Security's (DHS) SAVE program and the Social Security Administration. For applicants who cannot immediately provide documentary proof, states must create a process allowing them to submit an attestation under penalty of perjury and other evidence, subject to an official determination and accompanying affidavit. Federal departments and agencies would be obligated to share relevant citizenship information with state election officials within 24 hours upon request to facilitate these verification efforts. The bill extends these new requirements to various voter registration methods, including applications processed at motor vehicle departments and those submitted via national mail-in forms. For mail-in registrations, applicants would be required to present their documentary proof of citizenship in person to an election official or at a polling place. The legislation also strengthens enforcement by expanding the private right of action to include election officials who register applicants without the required proof and introduces new criminal penalties for executive branch officers who assist non-citizens in attempting to register or vote, or for officials who register applicants without proper documentation. Furthermore, the Act mandates that DHS investigate for removal proceedings if an alien is found to be unlawfully registered to vote. While the bill takes effect immediately upon enactment for new voter registration applications, it also modifies NVRA exemptions for certain states, requiring them to adopt these new citizenship verification and removal provisions or enact identical state laws. The Election Assistance Commission (EAC) is tasked with issuing guidance on the implementation of these new requirements shortly after the Act's enactment.
