that may be the law but in 8 years here, I’ve never been asked by the police to show my passport. Just my DL. But if one is only a tourist, without a DL, then yes, they would need to show it.
As it’s been said many times, the requirements depend on the office. I moved the required funds to Thailand and applied to change my tourist visa to Non-O for retirement at the Chiang Mai office merely days later. The application was accepted and I was told to go back at the end of the month to get the stamp.
it really isn’t that simple. I had to make 4 trips to the consulate in Vietnam exactly because the needed documentation and requirements were either not mentioned on their website or were confusing.
do you happen to know if Chiang Mai is one of those offices? I have the funds in my Bangkok Bank account now but it was just deposited this week. I was planning to go to immigration on Monday.
