@AnTonyo *******
AND I'll explain better. He's on ONLY a 90 day Non-O visa entry that he got when he entered at the end of Sept.
The REASON he got that Non-O visa controls what extension he can get the first time. IF he got that Non-O visa issued in Italy based on retirement (AND it's noted on the visa sticker) he HAS to take the first year extension based on retirement.
IF there is no notation on the visa sticker in remarks stating why he got it (OR if he got it based on marriage to a thai) he can get a yearly extension based on marriage to a thai the first time.
Otherwise if it says 'retirement' on that visa he has to take the first yearly extension based on retirement and then the second year he can apply for an extension based on marriage
Now to answer your question; if he's married to a thai, then YES he can get the 60 day visit thai family extension on that 90 day Non-O entry (no matter what the reason was he got the Non-O issued for) ๐
