As a part of the Higher Education Act of 1998, Congress directed schools receiving Federal financial aid to assist students who have not yet registered to vote.
To register to vote, as a South Dakota resident, you may obtain a voter registration form at the Secretary of State's web site.
Once completed you should print and mail it to your respective county auditor office. If your home state is other than South Dakota, you may use the national form.
To be eligible to vote in an election the voter registration form is to be received 15 days before the election.
