As I understand it -immigration need to see evidence of 800000 Baht in the bank.
They do not specify how the money ended up in Thailand.
It just has to be there.
Monthly money is different.
The applicant has to prove it comes from outside Thailand-every month 65000 Baht.
If you use the SWIFT system -that is in itself is evidence enough.
Using Wise means you have to select -Long term stay in Thailand-option on the dropdown.
