What visa information do I need before moving to Chiang Mai as an American retiree with a disability?

Look at Hua Hin. Lovely beach town!

Chiang Mai has months of burning season. The air is so bad during that time, that many people leave and come back after. Air is still bad all year, just unbearable during burning season.

So Hua Hin tends to be dryer than most Thailand cities. This means less mold too.

If your disability is down to respiratory, i heard C. M has a few months of bad air due to burning crops, i believe

Thailand doesn’t recognize same sex marriage if you’re married to the one in your picture she won’t be able to get a dependent VISA she will need to do her own visa separate from yours 

Though it sounds like US persons receive regular SS all the time...

Unless US laws have changed, you may not be able to receive SSDI nor Medicare while outside the USA.

Your local RTE website..

I don’t believe your disability will be deposited in a foreign bank. There is always the possibility you will be required to do some kind of work

Most likely you'll be wanting to get a non-O retirement visa. The easiest and cheapest way for an American to do this is to get a tourist visa (consulates in US require you to get insurance if you get the non-O there) and then come to Thailand. Once you arrive open a Thai bank account (it can be difficult on a tourist visa but it's possible) and transfer 800,000 baht.

Once you have the money in the account you'll be able to go to immigration and apply for a non-O 90 day visa for retirement. Then after 60 days you can apply for the 1 year extension and keep doing that forever.

You would each need the 800,000 if you want to get your own visas, and if your spouse is over 50 some offices may require her to have her own.

But it might also be possible for them to do "trailing spouse" visa for free based off of yours. They would need to apply for this outside of Thailand (neighboring country) after you got your first 1 year extension though.

You’d need to give more information about yourself to get informed responses. Unfortunately the rules are dependent on nationality and age a lot of times.
