If you establish Texas residency before moving abroad (e.g., get a Texas driver’s license, declare domicile, and—when eligible—register to vote) and then register to vote using the Federal Voting Assistance Program (FVAP), your last U.S. residence will still be recorded as Texas after you move abroad. This means:
• Voting: You’ll remain tied to your Texas voting district. Voter registration is only a supporting indicator of domicile and not determinative on its own; questions about eligibility should be directed to election officials.
• Jury duty: Texas state courts source prospective jurors from both voter registration records and Texas DPS records (driver’s licenses and state IDs), so keeping a Texas license/ID can still trigger a state jury summons even if you do not register to vote. Federal courts sometimes use voter rolls, so FVAP registration may lead to a federal summons—though you can generally be excused if you live abroad.
