If you have the money (800k฿) in y'r bank account two months before application, maybe you can considder 'change reason of extension' to retirement. Most of the time you get y'r year extension the same or next day, without consideration period. So, if the money is in for 2 months after 20th of august, you can ask the year extension just after 20th of august (also re-entry permit) 🤷♂️
Well, e.g. There are different non imm I O visas for which you have to be 50 years-up to get this. So you entered Thailand on a so called 'visa exempt entry' of 60 days (Possible for US citizens/passport holders) not possible for every country ! I would look for DTV Visa or LTR Visa in y'r home country or neighbour countries (e.g. Laos, Vietnam. Cambodia is a bit difficult now) No experience because I am here on retirement extensions. Well, it needs some reading and maybe later ask some questions when you know a bit more cinc. this stuff. Good luck 🙏
Nikki Seven: You really need to tell us y'r age and passport country. Those are essential things to give advice. Conc. 30 days extension, did you buy a visa in y'r home country ? There are even 'visa on arrival' or 'visa waiver' for certain countries which also sometimes cannot be extended with 30 days. So yes, y'r right, it's quite 'a forrest' with possibilities, but that's why you must tell all those data.
? She does not tell which visa she has, if any. If she has a real tourist visa (bought from a Thai Embassy/Consulate or came in on 60 days visa exempt, she CAN get a 30 day extension. But...too little info for this so hard to say.
Well, he does not have the 800k฿ (yet) and seems to want long stay in Thailand. So to open bank account and save money to get the 800k฿, maybe this O-A is not too bad to start and have at least a year time. Later he can get 'the free year' (with requirements of insurance etc.) and/or get a non imm O in- or outside the country. Only needs one border hop/run.
Well, this is the website for banking with Kasikorn. But.......I think it needs separate registration. Have this (when there was no app) already 12-plus years, but with me it still works.
