Hi, I'm on a year extension based on being the legal father of a Thai child. My extension is due to expire next January. Is it possible to extend it outside Thailand? (Hong Kong or Vietnam Thai consulate perhaps?) or should I just do it at the immigration in Chang Wattana? Are the documents required to extend it (other than the money in a thai bank) the same as I used the first time or they would somehow required less documents being just an extension? Would I get an extra 3 months if I exit Thailand early January or should I apply for an extension before its expiration? Thanks
