Information for Students

  • You must be a resident of the state in which you register and vote. If you're a student from South Dakota who attends school in another state, you may need to determine whether you're a South Dakota resident or a resident of the state where you attend school. The important thing to keep in mind is that you may only cast your vote in one state.
  • Here's what South Dakota says about residency: Your residence is the fixed place where you live and to which, whenever you're away, you intend to return. You have residency in any county or municipality in which you actually live, so long as you don't have the present intention to leave that place.
  • If you determine you're a South Dakota resident, but will not be present in this state or will be away from your home district on Election Day, be sure to check the absentee ballot application requirements and deadlines. In addition, South Dakota residents who attend school in-state, but in a different election district, may be eligible to register and vote in the election district where they live while attending school.
  • To determine whether you're a resident of a different state where you attend school, be sure to check that state's residency requirements.

Identification Information

South Dakota says that you need to bring ONE of the following forms of identification:

  • South Dakota driver's license or non-driver identification card, or
  • Passport or other government-issued photo ID, or
  • Tribal photo ID, or
  • Current student photo ID from an institution located in South Dakota
