Update, I have just left Khon Kaen immigration doing My second yearly extension, which was due on11/4/2019
So I went in today as its 43 0days before.
I asked about the new rules and do I have to take a bank statement in when I do My 90 day report to confirm monies are still in the bank.
The response I received was no you don't have to do that, nothing has changed, just come as usual for your 90 days report.
