Can my wife apply for a Non-O visa as a dependent when I'm converting mine to a retirement visa in Thailand?

Would the other alternative be for your wife to apply for her own non-O based on retirement (if over 50)rather than as spouse?

This would mean you both having the banked money, but would avoid any risks or complication?

Better to apply for DTV in Australia they soft power. Then your wife applies as a partner. It's better option than non o ,it's 5 years for 10,000 bht other conditions but easy and only have to show 500,000 bht in your bank once

All you can do

@Neil *******

is you apply for the 90 day Non-O based on this reason

You wouldn't be converting anything 😮 You'd get the 90 day Non-O visa based on retirement in Oz before you come here, then you'd apply for a year "extension of stay" from that visa based on retirement at the immigration office for 1900baht

Sadly I don't think your wife is going to be able to get a Non-O visa from ANY thai consulate based on being the spouse of a foreigner on a Non-O visa 🙁 AND that visa isn't even available inside the country at the immigration office after she comes here either. It is not sold for that reason anymore.

Consulates the world over started discontinuing issuing that visa last year. At this time there is no way to get her the initial 90 day Non-O visa based on being married to a foreigner on a Non-O 90 day visa OR a from a year extension on a Non-O 🙁
