In most cases, college students can choose whether to register to vote (or stay registered to vote) in their hometown or to change their registration to their new residence. To register to vote in Colorado, you must be a resident for at least 22 days before the election.
Students may wish to discuss where to register to vote with their parents. It is important to know that a registered voter in Colorado is considered a resident of Colorado for income tax purposes and for motor vehicle registration/operation purposes.
