I can't tell either. But that could be an option at least in SE Asia. 😉 Is it possible to contact the embassy/consulate where you are applying? Try FB messenger, we got a couple of answers ourselves on messenger, although they would not answer e-mails/the phone.
I did not have this problem, because we were residing in none of our home countries when we applied. So I had lots of options for the kids (passport stamps, resident cards, certificates of residence issued by 2 embassies per child), but I don't think you'll have issues here. If you really can't think of anything (school documents, health insurance documents, whatever from the US with the child's name on it which a tourist cannot get?), then I guess you could just explain it in a cover letter. Obviously, if both dad and mom live in the US and are married, the kids are very likely to live there too.
Wondering how they were called now, not sure anymore, maybe STV. Those were special tourist visas that were a pain to apply for (high requirements, etc.). They were made available a bit before or during covid, I think. One could stay for 1 year in Thailand, or was it 18 months?
I'm not sure, but I don't think they would be reluctant to issue a multiple re-entry permit to a non-imm ED language student. Exiting Thailand and returning does not necessarily mean that you spend a lot of time outside Thailand.
Not sure if SETV are still issued, and they were not exactly hassle-free, if memory serves. Personally, I'd go for an ED visa, but you'd need to study Thai (or another language), and it's not exactly cost-efficient since you have to pay for the courses. However: No need to leave Thailand for a year, one can *theoretically* open a bank account, the school handles extensions, etc.
Participant(e) anonyme Mais non, de toutes façons il faut tous les combiner dans un seul PDF. Par exemple, les relevés de compte (les vrais, pas un « historiques des déclarations »), c'est 6 documents, tu seras bien obligé de les combiner. Rien que pour les documents financiers, j'ai combiné 8 documents dans un seul PDF.
