The U.S. election process, dates, and deadlines vary widely between states.
Further detailed state-by-state information, specifically for overseas and military voters, including ballot transmission options, can be found in the State Voting Requirements.
Please take note: Overseas citizens and military voters are required to file a new Voter Registration Application/Absentee Ballot Request every calendar year.
Local Election Officials in the U.S. will send absentee ballots to overseas civilians and members of the military 45 days prior to the date of the election - if they receive your request prior.
Comprehensive contact information for your Local Election Official and Absentee Voter Clerk can be found in the Election Official Directory.
