How is the proof of a successful Non O retirement visa application provided?

I got my No-OA retirement e-visa in USA at Thai Consulate like you are doing. The longest step is getting Thai health insurance from a Thai Ins Broker. Your Ins and e-visa is for 1yr.

If your health history review is sketchy don’t be surprised if only a fraction of your body is covered! Preexisting conditions and past surgeries determine your coverage but, don’t expect a reduced cost.

Me and many others have poor coverage and go the self- insured path. This required getting the Non-O visa, which is only available in Thailand.

I wish I’d come on a 90day visa and applied here for the Non-O. It would have been handled by a Thai Visa agent and is less work on my part.

Yep, its a pdf that will be on the same Thai Embassy / Consulate web site you uploaded your financial docs to. Just log in to print. Make sure once you enter Thailand with that printed pdf, do not use the Electronic/face scanning gates. See an Immigration Officer in person and give them both passport and printed pdf.

It comes as a pdf attached to an email. Print it out and hand it out along with your passport on entry
