I am an Indian passport holder, who works for a US company and currently waiting for my US visa renewal (don't know how many months it will take for that to go through).

Meanwhile, I am planning to get Thai DTV visa, so I can live and work from Thailand.

I am going to be in Vietnam for 2 months starting January and would like to apply for Thai DTV visa from there. For those who have gone through the process in Vietnam, would really appreciate if you can help answer these questions...

1. At any point during the visa process, do you have to visit the Thai embassy/consulate in Hanoi or HCMC?

2. Does it matter if I apply via Hanoi or HCMC?

3. I will be in HCMC first, then go to Da Nang and finally to Hanoi. I can spend 2-4 weeks in each city if needed. If I apply for DTV while in HCMC, and then move to Da Nang after a week, will it be an issue for DTV processing? This assumes that DTV is still in process after a week.

4. Similarly, if I apply for DTV while in Da Nang, but then move to Hanoi, will be in an issue for DTV processing?
