Yeah, they are not going to like you not having 6 months on your passport. The best case is that they will only stamp you in until the end of you passport so you won't get a full year extension.
I have an LTR visa. Normally they would have given me a stamp for 5 years out but my passport was to expire before that. They only stamped me in until the end of my passport. I did get a new passport and they transferred the visa and updated the end date of my permission to stay stamp.
You may also want to check to see if you really have an OA visa since you don’t seem to know how it works. Many people confuse the OA and O visas thinking “retirement” visa is an OA visa. They discover that they have an O visa which doesn’t require health insurance for a 1 year extension.
You should check to make sure the insurance you used to qualify for your OA visa when you applied in your home country will qualify for the 1 year extension of your OA inside Thailand. Typically they want you to have Thai insurance but if you have the right documentation then maybe non-Thai insurance will qualify.
Calm down everybody. Do whatever the heck you want to do.
If the question is - can I do a border run the same day then I would advise that maybe/maybe not but you will be pretty darn safe if you come back the next day.
I'm happy to hear the results of anyone with a DTV who tests the system and reports on it.
If you make less than $25,000/yr you don't pay tax on Social Security. I do have other income and I believe that I am paying the top tax rate on my SS of 85%. I don't know if there is a sliding tax rate in between.
One of the solutions to "fixing" Social Security in 1983 was to begin taxing SS.
In 2022 I bought a car and built a house in Thailand. I can't imagine doing that without having my Thai bank. I'm happy with my Thai bank.
