Student FAQ

I am a student for 8 months of the year.  Where should I register?
You have the option to register in the municipality where you are a student.  Alternatively, you may register in your hometown.  The choice is up to you.

If a student leaves for the summer, where do they vote for summer elections?

Leaving for the summer with intent to return.  If they do not intend to establish residency at any place they stay until returning for school in the fall, then they may vote absentee from their school address until they have resided for 10 days at a new school address.

I am leaving to study abroad for a year.  Do I lose my right to vote?
No.  If your permanent address remains in Wisconsin, you may vote according to that permanent address.
