Registering as a college student in North Carolina"A college or university student may register and vote in the county where they go to school if the student is physically present in the school community and does not intend to return to his or her former home after graduation. However, if the student intends to return to their former home after graduation, then they should remain registered in their hometown.
If the student does not know where he or she will go after college, they may register in their college community or remain registered at home. If a student registers at his or her school address, that registration cancels any previous registration." (ncsbe.gov)
