|Where to Register
If you are eligible to vote in Michigan, you must register where you maintain your principal residence in the state. As a college student, you can register from your campus address or the address where you previously resided before moving to campus (provided that you still view your previous address as your “principal” residence in the state).
The Bottom Line
MI will only keep one registration address so you have to choose whether home or school is going to be your "principal residence."
The 30 Day Rule
Always keep in mind that almost any change you make to your voter registration status will take 30 days to get through the system. Give your clerk enough time to get you onto the voter file before an election, or plan to vote at home if you change your address the day before the election. If you don't get your new registration in 30 days before an election, you aren't going to vote.
How to register
When eligible citizens who are not already registered to vote complete a driver’s license or personal
identification card transaction, they will be automatically registered to vote unless they affirmatively decline. Registered voters will have their records updated if their address or other information has changed
The deadline to register to vote is no longer 30 days before an election. Under the new 2018 law, voters may register in person, by mail, or online up to 15 days prior to an election. Voters may also register in person with their local clerk within 14 days of an election, up to and including Election Day. A voter registering in the final 14 days, including Election Day, will need to show proof of residency in addition to proof of identity (or an ID that proves both). A voter wishing to register on Election Day must do so with a city, township or county clerk, or a deputized staff member. These individuals are usually NOT at the polling location, so it is best if the voter goes directly to their city of township clerk's office.
Other things you need to know
The law requires Michigan residents to use the same residential address for both voter registration and driver license purposes. Therefore, if the address you submit on a voter registration application does not match the address on your driver license, the Department of State will mail you an address update sticker for your driver license. (The address update sticker will be handed to you if you register to vote in a Secretary of State branch office.)
Regardless of the address you use for voter registration and driver license purposes, you can maintain a separate “mailing address” if you wish to receive mail pertaining to your voter registration and driver license at a different address.
You are free to change your voter registration/driver license address as frequently as needed. No fees are assessed for address changes.
The Bottom Line
Since MI only keeps one "principal address" on record for your driver's license and your voter registration, if you change one, you'll change them both. You can tell where you're expected to vote if your driver's license is current.
