U.S. expats have plenty of time to register to vote in the Nov. 6 federal election. They have a right to do so no matter how long they have lived overseas.
Several organizations exist to help expats register and obtain their absentee ballot. Probably the best known is the non-profit Overseas Vote Foundation that also operates Youth Vote Overseas mostly for U.S. students in foreign countries and several other initiatives. The Arlington,Virginia, based organization is non-partisan.
The Democratic National Committee also has a program to help overseas voters, be they expats or military. It is Vote from Abroad.
The U.S. government has the Federal Voting Assistance Program.
All have set ups so that expats and others eligible to vote can register at their designated state and submit requests for ballots. Some states allow online registration and online ballot requests.
In some states, the primary election already has passed. In others, there still is time to vote in the party primaries. Every site appears to have detailed information to answer any questions expats may have.
Local organizations affiliated with the U.S. political parties also have staged voter registrations in the past and will likely do so again this year.
