You should return your voted November 5, 2019 General Election ballot before October 16.
Here’s why returning your ballot before October 16 is important for this election: The Universal Postal Union (UPU) is a worldwide body that establishes and agrees on international postal rates. The U.S. has announced it may pull out of the UPU. If we do, there will be no agreement for mail to be delivered to or from our country to any other country after October 16, 2019.
Although the U.S. Postal Service and others have been working on contingency plans, those plans are unlikely to be in place in time for military and overseas citizen (UOCAVA) voters to return their ballots in time for the November 2019 elections.
