U.S. citizens in Costa Rica have options if they plan to cast a vote in the November elections.
The federal government maintains a Web site where overseas Americans can find information about voting and even ballots for federal offices.
Any U.S. citizen in Costa Rica can vote in the state where they last lived. That would require contacting directly the county clerk or similar official in the area where they lived. These ballots also include state and local offices and even local referendum questions.
The mail systems being what they are, expats might want to pay to return their ballot via an express service like FedEx. Sometimes these services agree to carry ballots for free as a promotional service.
The U.S. Embassy maintains information on its Web site about voting although unlike some other countries, including Costa Rica, U.S. citizens cannot vote at their embassies.
