Can my husband apply for a retirement visa when he turns 50, considering he is currently on a dependent visa?

I’m not sure why you’d want to. Doubles the funds needed or relies on juggling funds from one account to another with expert timing. If you have a “retirement visa” /extension of stay based on being over 50 he can piggyback off the back of that.

Another thing you might be able to do is you get your extension and he gets his based on being married to you. THEN 6 months later he goes to the immigration office wiht the correct documentation, cancels the extension he's on (based on marriage to a foreigner on a long stay extension) and immediately apply for a new yearly extension based on him being 50.. I don't know if an immigration office will do it or not. BUT in theory it would work because he's changing the reason for his extension.

I'd certainly ask at the immigration office before you try it though..

Good Luck

IF your two extensions (yours based on retirement and his based on being married to someone who has a long stay extension) expire at the same time then you're not gonna be able to do it.

The only way to do that would be to have your husband exit the country without a re-entry permit, which would cancel his current extension. Then he could either get a 90 day single entry Non-O visa at a thai consulate nearby based on being over 50. OR he could enter on a 30 day visa exempt entry and then apply for the 90 day Non-O inside the country at the immigration office.

After that he could apply for the yearly extension of stay.

That's the only way you'll be able to "split" the two extensions you have now by the 6 months you need to juggle the funds

If he want to have his own Visa or his own Extension of Stay he need to meet the financial requirements requested for it. As different kinds of visa and the Extension of Stay is called a "retirement" visa, I can not tell you the requirement needed.
