Can I have the required 800,000 baht in my Thai bank account when applying for the OA retirement visa outside Thailand?

When applying for the OA retirement visa outside of Thailand, you can have the required 800,000 baht in your bank account, either in Thailand or elsewhere, depending on the consulate's requirements. It's advisable to check with the specific Thai consulate you are using to ensure they do not require certification of the funds from a Thai bank. Generally, providing a bank statement showing the required amount, with your signature notarized, will suffice.
