If a person goes to another state or precinct and files an affidavit of residence in that state or precinct for election purposes, the person loses residence in the former state or precinct, unless the person moved to the other state after that state's deadline for registering to vote in a particular election.5. A student who resides at or near the school the student attends, but who is also able to claim a residence at another location under the provisions of this section, may choose either location as the student's residence for voter registration and voting purposes.6.
