The bill establishes a new section, 48A.25B, which mandates the verification of United States citizenship for individuals registering to vote and for 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 all registered voters. 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.

Furthermore, if the registrant fails to provide the necessary proof of citizenship within ninety days of receiving the notice, their registration will be canceled. The state registrar is also tasked with monthly verification of newly registered voters and annual verification of all registered voters. The bill includes provisions for the state registrar to adopt rules for the administration of this verification process.
