Non-o based on retirement. "O" stand for other and there's a list of "other types". You want the one that is for over 50 based on retirement from the drop down selector.
Why do you want an OA rather than O? No insurance, medical certificate or criminal background check required. And you have 30 days after you arrive to get the financial piece together. After the first year, they are effectively the same. Remember the older you get, the higher your insurance costs. Once you pass 70 it can b be cost prohibitive (from a value perspective).
It's pretty straight forward, though tedious. You need 800k in Thai bank for 2 months to get your first 1yr extension. You will need to effectively leave this in the bank (you can draw down during certain period but that only complicates the discussion). 2wks before your 90day non-o is to expire, take a trip to the bank asking them for a letter and 12 months of statements (generally they request 5 business days to process). 1wk before your non-o is to expire, go to the bank to pick up your statements and letter. Deposit a small amount and get your passbook updated. Go to immigration on that day with all required documents. Keep depositing at least 65k each calendar month forever.
When it's time to do your next 1 year extension, do the same process and ask immigration if you qualify for the 65k/month method. If yes, you can draw down your bank account to near zero if you need/want to.
Lots of steps but all very easy. Can be a bit tedious, but everything in Thailand is. Thai's love paperwork, rubber stamps and staplers!
not sure which immigration offices that applies to... I was told that they do not care where the initial ฿800k comes from. I'm not clear if there's a difference between getting non-o abroad where the ฿800k must be seasoned and doesn't matter where it comes from, or getting the non-o in country where the ฿800k is required to apply.
Usually bank wire is cheaper for larger amounts. Bank fees for sending wire transactions vary. Check with your bank and do the arithmetic to see if wire or Wise is cheaper for the amount you are transferring. For me, break even is about ฿150k but your mileage will vary.
There's a good chance you will have to apply for a new non-o. If you're next extension isn't until mar-2026, how did you get your extension that would start Mar-2025?
I believe most want it current within the last 5 business days. Your passbook showing current balance should be obtained on the day of your extension application.
