What is the financial requirement for extension (2nd year) of guardian visa (parent of Thai child)? I did my initial guardian visa on July 20, 2020. I will extend it before July 20, 2021. How much money do I need to show coming from an international transfer, and how long does the money need to be in the bank (seasoned)? When I get the letter from my bank showing the funds have seasoned, how long is the letter valid to be used for the visa extension application (e.g. 1 week)? Also, what is the earliest that I can apply for the extension? I am in Hua Hin. Thank you.
