Just need your expertise on this-I'm currently in Bangkok but planning to fly to the US for like 10 days to get vaccinated, etc. I will have a BOI visa by then with a reentry permit. I know you are supposed to apply for COE once you are outside of Thailand. I'm a bit worried that Consulate in the US may not issue me a COE before the departure flight. Is it possible to get approval before going to the US so that I get more time? Maybe I'm missing something-please let me know.
TLDR : Answer Summary
The user is currently in Bangkok and planning a 10-day trip to the US for vaccinations while holding a BOI visa with a reentry permit. They express concern about obtaining a Certificate of Entry (COE) since it is typically required to be applied for from outside Thailand and worry about the timing of approval from the US consulate.
