Hello everyone. I'm new to the visa stuff. I'm USA citizen living in USA. I'm looking to move to Thailand this summer around June. I want the longest visa possible that is not one of those elite visas. Too expensive for me. It will be me and my son (USA citizens) and my Thai girlfriend (USA green card/Thai citizen. I saw there is an STV visa that is good to renew up to 270 days but the program ends this September. Will the visa be able to be extended past September or does immigration refuse to extend at the city off date? If the cut off date ends the visa how can I stay longer without leaving Thailand? I am looking to retire there but am only 48. I need another year and a half before I can get the retirement visa I believe. Thank you for any assistance.
