did you use your own money in the bank or did they agent use their money?
Did you convert to a 90 day non-O inside of Thailand last year and also get the 1-year extension at the same time, so 15 months in total? If you did that and both your non-O visa and 1-year extension have the same date, you won't be able to apply for anything on your own. You'll have to use an agent again next time.
If that's the case, you go to the main immigration office at Chaeng Watthana to apply for your extension based on retirement. You're not getting a 1 year retirement visa, as you already have the retirement visa. You're just applying for an extension.
there is no number of days to leave. The moment the divorce is final, the extension is invalid. Most people will know ahead of time and plan accordingly.
The owner of the group got notice from immigration that for extension purposes, foreign women married to Thai man will remain the only ones who do not have to show financial proof. All other marriages will require proof of funds. Thai male foreign male, thai female foreign female, Thai female foreign male.
I've yet to hear of anyone getting a visa or extension within Thailand based on same sex marriage, but based on the immigration policy, I would not expect there to be any preference to any other marriage type except Thai man with foreign woman
