yep, sounds like your first 90 day report is due about Jan 8, 22 (90 days after entering Thailand.) Keep in mind that you can report up to 15 days before your due date and 7 days after.
I learned something new today because of your response to this question. I'd just like to take a moment to thank you for all of the wisdom you routinely impart on this group. Unlike some of the other more knowledgeable members, who are IMO far too often condescending and even borderline abusive, you never fail to be polite and helpful, regardless how trivial the question may be. I for one, truly appreciate what you bring to this group. Thanks again and have a happy Halloween!!
I see that you are in Phoenix (opposite side of the country) but here's a list of round-trip flights from NYC to BKK and back. I'm not sure what you consider expensive in 2021 but I'm quite confident $750 US round-trip is a good price. However, with petroleum prices rising, I doubt that they will remain this low.
I was thinking the same thing. 47K X 12mos = 564K plus the 650K he has in the bank is more than enough. However, I think the question may be do the 47K monthly deposits show as arriving from outside of TL on his bank statement?
