Voter registration; requiring persons registering to vote to provide documentary proof of citizenship. Emergency.

SB 1667 requires all Oklahoma voters to provide documentary proof of U.S. citizenship when registering to vote. Applicants must submit specific documents like a birth certificate, passport, naturalization papers, or tribal enrollment card to verify citizenship. Election officials must verify this proof before classifying a voter as "verified," and non-citizens (referred to as "federal-only voters") cannot vote in state elections without using provisional ballots. The bill directly affects anyone registering to vote in Oklahoma, adding a new verification step to the registration process.
