How can I successfully extend my non-immigrant "O" visa based on marriage in Thailand without complications?

@Kool ******

it’s not a waste of money for agents. It’s a peace of mind and ease of process. That is - if u can afford it.

, that was last year when you changed over from retirement to marriage/Thai wife. This year has no comparison to last year. New year. Forget what happened last year. This is a new year, and there is a difference in how the money is treated, AND, not all the regulations are written in their handouts. The first difference, and problem you might run into is that you should start your marriage extension renewal at least 30 days before it expires. They are requiring the 12 months of deposits coming in from overseas of at least bt40k a month, every month, without exception, or bt400k in the bank for at least 3 months. It can not be a combination like it used to be. After all your documents are accepted, the same documents as last year, with all new pictures, and new letters from your bank, one stating that it is your personal account, and the other showing each months deposit from overseas of at least bt40k. Your updated bank books, that day, showing all your deposits. Then you get your 30 day waiting period stamp, just like last year, and when you come back, they want to see your updated, that day, bank books again, with copies. That is it. I just did it for the fourth year last May, at ChiangWattana. One thing you have to remember about Thai culture, and what is called "face", is you never show an officer that is making a decision about your life basically, that he/she is wrong. Immigration officers have the ability to, at their discretion, reject, or approve you. You have the opportunity to appeal their decision, but, if you try to show them as being wrong, they can loose "face", and that can be very bad for you. Be nice. Say okay, and do what they say, or you could be leaving Thailand, and not by your choice. It very seldom happens that extremely, but it does on ocassion. Play the game, as it is their game, and they make, and can change, the rules. You need to get in to renew your extension right away, as now you are on about two weeks, instead of the 30 days.
