@Kim ******
at this time only ONE immigration office will issue the 90 day Non-O visa based on being the 'trailing spouse" of a retirement visa holder and that is Phuket.
Before that there wasn't an immigration office in the country that would issue the 90 day Non-O visa for that reason.
So you wanna get a 'piggy back' visa as the trailing spouse of a retirement visa holder you do it there or you go out of the country to get one after your husband has his non-o visa and then the year extension.
