My U.S. ten year passport expires in 18 months. When getting a renewel the number changes i think. With the DTV being five years would I simply inform the Thai consulate of the new number?
TLDR : Answer Summary
When renewing your U.S. passport, the passport number will change. For your Thai DTV visa, you will need to inform the Thai consulate or immigration office. It's advisable to use both your old and new passports during entry and exit. If you've previously transferred a visa from an old passport to a new one, you should visit the U.S. embassy for a new passport and then go to the immigration office to transfer the visa, ensuring the visa's passport number matches your new passport.
