While regular absentee voting ends at 5 p.m. on the Saturday prior to the election, you may qualify for emergency absentee voting in a few, limited circumstances. If you have any questions, call the Registrar's Office at 757-890-3440.
The State Board of Elections has a helpful page on absentee voting, including information for overseas citizens and members of the uniformed services, on the Absentee voting page.
