Good morning.

To obtain the non-immigrant O retirement visa annual extension using the sum of the bank deposit and pension income, is required a sort of income certificate, but it's not clear to me, I need to find precise and reliable information on which documentation must be shown to demonstrate the requirements (again: the sum of the pension income and financial deposit that reaches a total of 800,000 baht).

In addition to the obvious bank statement, I don't exactly understand what must be shown regarding the pension income and where, a possible document, can be requested.

Thanks for the help, it will be precious as usual. 🙏
