Automatic Voter Registration Act This bill amends the National Voter Registration Act of 1993 to require state motor vehicle authorities, upon receiving certain identifying information with respect to an individual requesting motor vehicle authority services, to transmit the information to the state election official. The state election official shall then notify the individual that unless the individual declines to be registered to vote in federal elections in the state, the individual shall be automatically registered unless the individual does not meet voter registration eligibility requirements or is already registered to vote. A state may not use any identifying information regarding an individual's citizenship status for any purpose other than determining whether the individual is eligible to vote in federal elections.
