Voters should register as early as they can! We recommend you try to get your form filed well in advance of the election date, and no later than 90 days before the election.
Most filing deadlines are 30 days prior to the election, and you can check the deadline in your state by using our Election Dates and Deadlines directory. Be sure to click the box that says, "Overseas & Military Voters." Remember, you'll need to allow extra time to have your application processed and your ballot sent to you overseas.
Note: Many states now allow fax and email options for registration and ballot requests. Unless you have an active registration and original signature on file with your local election officials, however, those methods require that you follow up with a form via postal mail.
