I see now that immigration requires a letter from your Thai bank stating that your balance has come from overseas. Is this a long process or can they do it for you immediately.

TLDR : Answer Summary
The process of obtaining a bank letter that shows overseas funds can vary in duration depending on your bank. Immigration often requires a detailed letter to support applications for visa extensions, typically involving proof of consistent foreign transfers over 12 months and additional documentation like bank statements. Many users report that some banks can provide this letter quickly, within 30 minutes, while others may take 2-5 days. Preparation in advance, including having detailed records of transfer dates, can expedite the process.

 the 800k doesn't need to be from an international transfer for an Extension of Stay based on retirement, just 2 months seasoned (and the requirements met for the previous year if applicable)

I'm wondering how this would work if you're using Wise to convert your home currency into Thai baht and then transferring into Thai bank account?

 you select the reason for transferring the money, usually "for long term stay in thailand" and it will show as a foreign transfer.

 I've been using wise for several years now. Only in the beginning did I have an issue with the FT. Apparently, if you contact them,,they " flag" your transaction and it seems to work. Every transaction I do now comes with the FT. Unfortunately, if I ever need money quickly, it don't happen, it's always the same slowish route, which is usually ar18 hours ish

I assume you are applying for an annual extension of stay based on having 12 months of minimum 65k baht transfers from overseas each month? The letter needs to pull out those transfers and show them line by line. You'll also need 12 months of bank statements and to update your bank book on the day you apply.

 Only if you are converting from a tourist entry to a non-O is it required to show the money came from overseas. For an extension using 800,000 baht in a Thai bank account, there is no requirement to show that.

 there's no requirement to show the money is from overseas for an extension based on 800k baht. You still need a letter from the bank but it's a different format. I always just ask for a letter for immigration and my bank understands what's required

 you can't do that to apply for the initial 90 day Non-O visa as when you put the money in a bank account it won't show as coming from overseas. For an extension of stay you could do it.

It's called a credit advice.

You need some preparation by writing down all dates your money wired in. The bank will pull out foriegn transfer records on those days more quickly for you.

 It might depend on the office. I did it last week in Phuket, though. The statements contain the bank logo and all the same information as what you would get from the branch.

 This apparently is not the letter that just confirms your balance is more than 800,000 but states it has come from overseas.
