On September 11, the voters who formerly lived in Illinois, and who now live in Guam, Puerto Rico, and U.S. Virgin Islands, filed this reply brief in the U.S. Supreme Court. The case is Segovia v U.S. The Court has put the case on its October 5 conference.
U.S. citizens who move to a foreign country retain the right to vote absentee, in the state in which they lived before they left the country. In Illinois, if they move to American Samoa or Northern Mariana Islands, they also retain the right to vote absentee in Illinois elections. The only places in the world that are fatal for the ability to continue to vote in Illinois are Guam, Puerto Rico, and the U.S. Virgin Islands.
