What is the current requirement for holding 400K in a Thai bank for a Non-Imm O visa Extension of Stay?

Yeah, different rules depending on where. Why? Because if an office had to admit they do it the "wrong" way, they would "lose face." Therefore, they just continue doing it that way, until nobody's quite sure which way is wrong or right. That's just how they do it, and it makes perfect sense to them. Fascinating country! I used to think they were looney tunes, but now I'm not so sure. Does that mean I'm looney tunes now? Maybe. Does it matter? No, all that matters is that I figure out how they want me to do it, I think.

My local office at Pathum Thani immigration only want to see the bank book at the time when applying for the extension. When I return after 30 day's to get my final stamp no bank book is need... different immigration offices different rules.
