Eligibility Requirements

Overseas Voters

U.S. citizens living abroad have the right to vote as absentee voters, provided they are eligible to vote in their state. If you are living outside of the U.S. permanently, indefinitely, or temporarily, your voting rights stay with you, even if you never voted when you lived in the U.S. To vote from overseas:

  • Complete and send an overseas voter registration/ballot request form to your election office in the U.S. This is one specific form that will register you as an overseas voter and request your absentee ballot – simultaneously.

Many states allow children who were born overseas, but never lived in the U.S., to use their U.S. parents’ last residence address to register.

Military Voters

Service members and their eligible family members living outside their voting jurisdiction (within or outside the U.S.) are able to vote as absentee voters.

  • If you are a service member, or an eligible family member, there is a single form to file for both voter registration and ballot request. It is often called the “Federal Post Card Application” or the FPCA form. This form must be re-filed with your election office each time you change location.

To vote as a service member or eligible family member:

  • Complete and send a voter registration/ballot request form “FPCA” to your election office in the U.S. It is the same form in all states.
