The bill establishes a new section, 48A.25B, which mandates the verification of United States citizenship for all registered voters in Iowa. The state registrar of voters is required to utilize the systematic alien verification for entitlements system from the United States Citizenship and Immigration Services to confirm the citizenship status of registrants. If a registrant is found to be unverified, the county commissioner of registration must label their records as unconfirmed and notify the registrant, providing them with options to either cancel their voter registration or submit proof of citizenship. If proof is not provided within ninety days, the registration will be canceled.

Additionally, the bill stipulates that the state registrar must conduct monthly verifications for newly registered voters and annual verifications for all registered voters. The registrar is also tasked with adopting rules to effectively implement these verification processes. This legislation aims to enhance the integrity of the voter registration system by ensuring that only eligible citizens are allowed to vote.
