I cannot find information about 90-day Non-O retirement visa category in Thai consulates in US.

I can find information about Non-O family and volunteer work visa or one year Non-O (Long stay) retirement visa information.

Please post links to any Thai consulate in the USA that issues 90-day Non-O Category retirement visa that I can extend to one year inside Thailand.

While I am relaying second hand information, it is my understanding that Non O visas for being over 50 are no longer issued at the consulates in the US. You are told to apply for a Non O-A visa (with more onerous requirements) and cannot apply using the honorary consulates.

You will need to get a non 'O-A' in the US and extend that once in Thailand, or enter Thailand as a tourist and apply for a non 'O' as a prerequisite to the extension process.

I suggest you contact one of the honorary consulates about a single entry non-o visa. A far as I know there is no mandate that they cannot issue them. Contact info here: http://thaiembdc.org/royal-thai-honorary-consulates-general-in-the-u-s/
