Are there minimum balance requirements for a marriage visa in Thailand similar to the retirement visa?

For a marriage visa extension in Thailand, the general requirement is to maintain a minimum balance of 400,000 baht in your Thai bank account for at least two months prior to your application. Unlike the retirement visa, there are no ongoing requirements to keep this balance for a specific period after the extension. However, it's advisable to check with your local immigration office, as some may have different requirements.
