Remember: college students can register to vote where they go to college. However, you might consider registering in your home state/territory if you think you might move back after you graduate and instead vote by mail while in college.
Think you might already be registered?
Different states have different requirements and deadlines, so make sure you look into it early to give yourself enough time to request the ballot and return it for the primary and/or general elections.
