Do I need 800,000 baht in my bank account for two or three months before applying for my visa extension in Thailand?

To apply for a retirement visa extension in Thailand, you generally need to have 800,000 THB in your bank account for at least 3 months after your last extension. However, some offices may only require 2 months, especially for initial applications, while others might maintain a 3-month requirement for subsequent extensions. It's also worth noting that if you're applying from abroad, such as London, the requirements can be more lenient, allowing for just 1 month of maintaining the balance.
