MS SB2237

Requires voter registration applicants to submit one of four types of documents proving U.S. citizenship: birth certificate, U.S. passport, naturalization documentation, or documents meeting Immigration Reform and Control Act standards.

Amends voter registration application forms to include a section for applicants to indicate citizenship status and instructs applicants to submit proof by presenting required documents.

Requires county registrars to verify citizenship documentation for mail-in registration applications before processing, with applicants able to provide naturalization certificate numbers subject to verification with Department of Homeland Security.

Establishes registration as incomplete until proof of citizenship is submitted for in-person applications, and rejection as grounds for mail-in applications if documentation is not attached.

Takes effect July 1, 2020.
