You fill out the Federal Post Card Application, request an absentee ballot from your last U.S. state of residence, and mail it back before your state’s deadline.
What Is the Federal Post Card Application?
The FPCA (Federal Post Card Application) is the single form that registers you to vote and requests your absentee ballot. It is issued by the Federal Voting Assistance Program (FVAP). Every U.S. citizen living abroad uses this form, regardless of which state they vote in.
You vote in the state where you last lived before leaving the U.S. Your voting address is your last U.S. residential address. It does not matter that you now live in Tijuana or La Paz. Your state considers you a resident for voting purposes until you establish residency in another U.S. state.
Submit a new FPCA every calendar year. Most states require annual renewal. Some states keep you registered for longer, but filing annually guarantees you receive ballots for primaries, general elections, and any special elections.
How Do You Fill Out the FPCA?
Go to votefromabroad.org. The site walks you through the FPCA in under 10 minutes. It is nonpartisan. Available in English and Spanish. You enter your U.S. voting address, your current Mexican address, and your identification details. The site generates a completed FPCA ready to submit.
You can also fill out the FPCA by hand. Download the blank form at fvap.gov/uploads/FVAP/Forms/fpca.pdf. Print it, complete it in ink, sign it, and mail or fax it to your state’s election office.
Most states accept the FPCA by mail, fax, or email. Some accept online submission. Check your state’s rules at fvap.gov or overseasvotefoundation.org. Each state has different deadlines and submission methods.
What Are the Key Deadlines?
FVAP recommends submitting your FPCA by January 1 of any election year. The absolute latest recommended date is August 1 for November general elections. Earlier is better. Late submissions risk missing your state’s registration deadline.
States must mail ballots to overseas voters at least 45 days before a federal election. For the November 2026 midterms, that means ballots ship by mid-September 2026. Your state sets the exact date.
Your completed ballot must reach your state election office by your state’s deadline. Most states require receipt by Election Day. Some accept ballots postmarked by Election Day. A few give a grace period for overseas mail. Know your state’s rule. It is the single most important detail in this process.
How Does the Ballot Reach You in Baja?
Most states mail your ballot to your Mexican address via international post. Correos de Mexico (the Mexican postal service) delivers it. Delivery times from the U.S. to Baja vary. Tijuana addresses receive U.S. mail faster than addresses in BCS. Budget two to three weeks each direction.
Some states offer electronic ballot delivery. They email you a blank ballot as a PDF. You print it, mark it, and mail the completed ballot back. This eliminates one leg of the postal transit. Check if your state offers this option. It is the fastest way to receive your ballot.
If you have a U.S. mailing address (P.O. box, family member, mail forwarding service), you can use that as your ballot mailing address. Many expats in Tijuana use a San Diego P.O. box and pick up their ballot when crossing the border. This is the most reliable method for Baja California residents.
What If Your Ballot Does Not Arrive?
Use the Federal Write-In Absentee Ballot (FWAB). This is your emergency backup. If your official ballot has not arrived 30 days before the election, fill out the FWAB and send it to your state election office.
The FWAB covers federal races (Congress, Senate, President). Most states also accept it for state and local races. Download it at fvap.gov. The form is straightforward. You write in your candidate choices by name.
Your FWAB counts only if your regular ballot does not reach your election office by the state deadline. If both arrive, the regular ballot takes priority. There is no penalty for submitting both.
Can the U.S. Consulate Help?
The U.S. Consulate General in Tijuana is at Paseo de las Culturas s/n, Mesa de Otay, C.P. 22425. They have a Voting Assistance Officer who can help you fill out the FPCA and notarize documents if your state requires it. In some cases, they can transmit your ballot via diplomatic pouch.
The U.S. Consular Agency in Los Cabos is at Las Tiendas de Palmilla L-B221, Km 27.5, Carretera Transpeninsular, San Jose del Cabo, C.P. 23406. Services are by appointment only. Email ConAgencyLosCabos@state.gov to schedule. The Consular Agency offers more limited services than the full Consulate in Tijuana.
Both offices can provide blank FPCA forms and general voting guidance. Neither office can tell you who to vote for, register you directly, or guarantee ballot delivery times.
What About State Taxes and Voting?
Registering to vote in a state does not automatically make you a tax resident of that state. However, some states (like California, Virginia, and New Mexico) have complex rules about residency, taxation, and voting. If you are concerned about state tax implications, consult a tax professional familiar with expat issues before filing your FPCA.
Most states do not impose state income tax obligations solely because you vote there as an overseas citizen. But the rules vary. Do not assume. Check your state’s specific policy.
What Is the Step-by-Step Timeline?
January: Submit your FPCA for the year. Use votefromabroad.org or fvap.gov. This covers all elections in the calendar year.
Spring: Watch for primary election ballots if your state has competitive primaries. Primary dates vary by state. Some arrive as early as March.
August: If you have not yet submitted your FPCA, do it now. This is the last safe window for the November general election.
September: Your state mails general election ballots at least 45 days before November. Check your mailbox (U.S. or Mexican) regularly.
October: If your ballot has not arrived by early October, submit the FWAB immediately. Do not wait. Mail from Mexico to the U.S. can take two weeks or more.
November: Election Day. Your ballot must reach your state election office by the deadline. Some states require receipt by Election Day. Some accept later postmarks. Know your state’s rule.
What Are the Common Mistakes?
Using your Mexican address as your voting address. Your voting address must be your last U.S. residential address. Your Mexican address is only your mailing address.
Missing your state’s return deadline. International mail is slow. If your state requires receipt by Election Day, mail your ballot at least three weeks early. Use a courier service (DHL, FedEx, UPS) from Tijuana or Cabo if you are cutting it close. DHL offices in Zona Rio (Tijuana) and San Jose del Cabo ship to U.S. addresses overnight.
Forgetting to sign the ballot envelope. Every state requires a signature on the outer envelope. An unsigned ballot gets rejected. Check before you seal it.
Not submitting the FWAB as backup. If your ballot is late, the FWAB is your safety net. Submit both. There is no penalty.
