But you are much too quick. If you have the 'O-A' then enter before 30 sept. And you already have an extra year as James Miller stated ! Rules can change in one and a half year....
Just a thought: Can't you come in on a 30 exempt entry (30 days) and extend it by 30 days at an immigration office ? When you only want to stay for 60 days.
Tod, just a question. Can you switch the income reasons for the year extension ? When e.g. you used banked money before and now use an income statement (65K ฿; Dutch) from the embassy and visaversa ?
Thought so. So that's maybe also the hassle. He did not understand the problem. But got back in Thailand already with a 60 day stamp. So don't need to correct the first stamp I guess.
Ok. Got my second year extension ! And indeed, they changed my 90 day report date to 11th of March. So you can add Korat with same procedure as Krabi and Khon Kaen
