I am asking for a Swiss friend, as he is not capable of proficient English to follow the conversation. He is in a same sex marriage, officially married in Switzerland. His partner wants to apply for the 365-days Non-Imm-O visa based on retirement (he is over 50 and fullfills the financial requirements). As soon as his partner will get the visa issued, he wants to apply for the "90-days Non-Imm-O as a dependant of a foreigner holding a longstay permit for Thailand".
So my question is:
Do Thai Embassy or/and the Thai Immigration allow the "dependant" (trailing spouse) method in a same sex marriage?
