Why you paying 8K for an extension when you have 800K in the bank? I see now, an agent. Why pay an agent when you can do it yourself if you have funds in the bank? Waste of money. The extension is 1900 baht plus your Re-entry permits on top. You CAN have a bank account with a DTV as well. I am happy with a DTV, I find it easier than my Non-O and if I have to go back, I will get a Marriage visa and then have only 400K tied up instead of 800K. Yes, I finally got married after 30 years. It's not the money, I can afford it but resent the reasoning. Why the hell should I have that sitting in a Thai bank year after year and the hoops about seasoning and taking this out but not that, and making sure it's back in two months before next application etc. Even a small amount like 800K can get 5% interest in the UK.
