You can generally vote by absentee ballot if you will be away from home on Election Day. Many states also offer in-person early voting in the days or weeks leading up to the election. Visit the HeadCount Early and Absentee Voting page to request an absentee ballot or get information on how to vote early.
Many states allow no-excuse absentee voting by mail (which you can complete before Election Day). More than half of U.S. states offer in-person early voting as well. Visit the Headcount Early and Absentee Voting page to get more information or request an absentee ballot.
