Apologies in advance if this has been covered before. I have an appointment to extend my Non-Imm O visa (issued in Vientiane) at Bangkok immigration on Friday based on marriage to foreign (US) spouse. I have Irish passport. Does anyone have experience of what documents are needed to complete this? We have full proof of marriage here in Thailand, spouse's work permit and letter from her employer. Is anything else required, besides the usual copies of passport, visa pareses, etc.? Thanks in advance.
