Do I need to show a year's bank statement or just 3 months when renewing my marriage extension visa with a 400,000 baht balance?

When renewing your marriage extension visa using a bank balance of 400,000 baht, you typically only need to provide the last two months of bank statements showing the required amount. Unlike the retirement visa, the marriage extension does not have a strict requirement for the funds to remain in your account for an entire year. It is recommended to ensure that the funds are in your account for at least two months prior to your renewal application. There are some complications with specific banks, such as Bangkok Bank, which may freeze your funds or complicate the process, so finding a bank that facilitates the immigration process, like KBank, may be advantageous.
