How does the DTV visa process work with an expiring passport?

When applying for a DTV visa with a passport that expires in one year, the process involves managing documentation properly. The DTV visa might not be stamped physically in your passport but is typically issued as a PDF file with a QR code. If you renew your passport before the visa application, the old passport is not needed. Ensure to carry both your old and new passports while your DTV visa remains valid, as it will be tied to the current passport.
