I entered Thailand via Chiangmai Airport today from Hanoi, Vietnam (13 June).
They sent off DTV holders to separated area next to the immigration lines to fill the interview form which basically asking the same information as TDAC form (personal info, arrival-departure flight/date,etc.)
I got asked to show the proof of money in my bank account. I just pulled up my bank app.
And asked about the address and what is the purpose of visiting/how long.
But overall it was not intimidating or anything.
It wasn't a long process just quick and straightforward.
Ps. This is first time entering with DTV visa
Just sharing some experience here if anyone was looking for. :)
