the banks rules for a foreigner opening bank account. If you can prove than 3 months medical treatment in Thailand.
There is no law against Bank account on DTV or even tourist visa. Banks make their own rules. They just have to follow anti money laundering laws from government. Which means more paperwork hassle for the bank. And they especially don’t like to open for Americans due to extra paperwork.
I have a Thai partner that called for me to check the rules. And i got a Bank account in first branch I tried (not the same she called)
Its gotten more difficult lately though, but if under actual medical treatment it should still be possible
