Students may consider their schools as their primary residence since that is where they spend most of the year and engage in community activities. If you are a student and you consider your school as your primary residence, with no present intent to leave, you have the right to register and vote from your school's address.
As a student you also have the choice to register to vote and to vote from your home address (whether parent, guardian, or other address), in-person at the home address' polling place. As a student, you can also request and vote by absentee ballot using your home address – but it is against the law to vote in both places.
In either case, in order to register, go to Register to Vote / Absentee Ballot. Choose the Type of Voting Form that applies to you and complete the registration process by filling out the information in each step. At the end, print and send your registration form to your local election official.
