U.S. citizens overseas are guaranteed the right to vote in federal elections in the United States. Please note that you cannot simply log on to a website and vote at the last minute. Almost all states require voters to physically send in registration documents, receive paper ballots by return post, and mail in their completed ballots. Adequate preparation is the key.
You cannot register to vote or vote at the U.S. Embassy or consulates. However, we do supply the forms necessary to request an absentee ballot from your last state of residence. Please visit the Federal Voting Assistance Program website at www.fvap.gov. This site has detailed information about absentee voting, including how to download, fill in and send the absentee ballot request form to the appropriate address in your state. For quick answers, consult the FVAP’s Voting FAQ.
