What is the downside of not doing 90 day reports? I know that you can get fined between 2000 and 5000 baht depending on circumstances. Can you get deported? Can you be refused an extension? If you are on a 1 year extension for retirement and you don't bother to report until the next extension is due, do you simply get a 2000 to 5000 baht fine and then another extension? What is the worst that can happen for simply not reporting?
