What are the requirements for maintaining the THB 800,000 deposit for Thai visa extensions?

The discussion centers around the requirements for maintaining the THB 800,000 deposit necessary for certain types of Thai visas. Commenters clarify that funds must remain in the account for at least three months after the extension is granted, with a minimum balance of THB 400,000 required for the rest of the year. Additionally, it's noted that while one immigration office in Jomtien requires proof of the deposit three months post-extension, most others typically check the account balance only during the next annual extension application.
