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?

What is the turnaround time for getting a new passport from the American embassy in Bangkok? I am trying to avoid a trip back to the States before my visa expires on June 24. 🙏

I have a U.S. passport. I have run out of pages. i have a non-O Retirement visa and it is extended until March 2020. Please tell me the procedure to get a new passport from the U.S. Embassy or Consulate and what forms fees are needed. Plus, any advice or insight into timelines.

Additionally, once I receive my new passport, how do I get it updated with Thailand Immigration. Again, what forms, fees and procedures are required at Chang Watthana (Bangkok District)?

Thank you!
