You paid 70k last time, you have more than 800k in the bank, and you're wondering if you should save the 1,900 baht by killing your visa/extension rights and going with free tourist entries instead? 🤔
Yes, crazy that you came to Thailand without checking the procedures. Are you serious about making a move to the Land of Smiles? If so show it some respect, you've admitted you were wrong so no need to try and spread the blame to Thai officials just doing their jobs
It's difficult for an attorney to advise you any better than some people here can. The main reason is that each Immigration Office interprets the rules differently and determines the evidence needed to show you meet them. This is especially true of how the monthly income works. Some IOs will only accept an affidavit from your embassy, confirming your income and it's sources. If you're from the US or UK, for example, your embassy will not give you that. So, for your first extension of 12 months you have no option but to show 800k in a Thai bank account. An agent can help you with this. In subsequent years your local IO might accept bank statements showing 65k per month for 12 consecutive months. Some will say the 12 payments should never be less that 65k and never late. Some will even say each month must contain ONE single credit of 65k or more (not always easy if you have several income sources that arrive on different dates). To use the combined method, again you have to ask your local IO how they interpret the requirement and how you can show evidence for it.
