Do I need to show proof of 500,000 baht in a bank account when re-entering Thailand on a DTV?

I don't think that's even a visa requirements. Like it just says that you need 500k when you're applying but unless my memory is wrong, there's no mention about having to keep the money available at all time. That being said I guess it depends on the agent so theory can sometimes differs from reality. But I haven't been asked for anything the two times I re/entered (workcation, they may be more strict with muay thai maybe)

Nothing was asked yesterday. Showed my print out straight through in a few minutes. (Chiang khong)

I crossed cambodian land border (ban pakkad) for 1minute and came back, no questions asked. Will do same to Laos in 3 weeks

Hey, I recently came back to Thailand after my first six months with DTV. Came back through Don Mueang Immigration. The officer didn't even ask for anything. They just scanned the QR on my evisa, stamped my passport and signed. No questions or issues at all

Not seen any posts where people have been asked to show the 500k on entry. It is for an extension in-country where you need to show it.

Very very few reports of anyone being asked for proof of ANYTHING when entering again. And no one reporting being denied entry on a DTV.

Thinking the same
