New absentee voting laws went into effect in 2012. You will no longer automatically receive ballots based on a previous absentee ballot request. All U.S. citizens outside the United States who want to vote by absentee ballot must complete a new Federal Post Card Application (FPCA) every year if they wish to vote from abroad. States are now required to send out ballots 45 days before an election. No matter what state you vote in, you can now ask your local election officials to provide your blank ballots to you electronically (by email, internet download, or fax, depending on your state). You can now also confirm your registration and ballot delivery on-line. Be sure to include your email address on the form to take advantage of the electronic ballot delivery option. This is the fastest and most reliable way to receive your ballot on time, and we strongly recommend every overseas voter take advantage of it. Learn more at the Federal Voting Assistance Program’s (FVAP) website: www.FVAP.gov/.
Remember that your vote counts, and that many U.S. elections within the past ten years have been decided by a margin of victory of less than 0.1%. All states are required to count every absentee ballot as long as it is valid and reaches local election officials by the absentee ballot receipt deadline.
