Does the $25,000 requirement for a Thai visa need to be in a specific type of bank account?

When you be better just to show you have an income so you don't have to worry about the bank deposit

Figure out what visa you want first

You do realize after you get your 90 day visa to get the 12 month extension here you will need to put that $25,000 in a Thai Bank Account where it must stay for 2 months prior to extension and 3 months after the extension. The account can’t go below 400,000 and prior to the next extension you have to return it to 800,000 two months prior.

For the second extension you can also show 65,000 Thai baht being transferred into your account each month as an international transfer which would alleviate maintaining 800,000

also can’t be cash in a brokerage account

Can't be in a CD, it should be in a normal, instantly accessible, bank account
