Just look at what people had to show to extend in Thailand ,the reason there is a financial requirement is because they want to know how you can live for 5 years without the cash,and why don’t you show me the LAW that says you don’t need it
Yes I can see wanting bank statements and some documentation of what your doing the soft power well you may have to continue classes I can’t see letting someone taking a cooking class exiting and entering Thailand for five years
800k in a Thai bank in your name seasoned for two months before your 1 year extension unless your embassy supplies an income affidavit which shows at least 65 k a month
