What are the seasoning requirements for increasing my bank deposit from 65k to 800k for a retirement visa renewal in Thailand?

To change your current banking deposits from the required 65,000 THB to 800,000 THB for your retirement visa renewal, you need to deposit at least 800,000 THB into a Thai bank account in your name. This amount must remain in the account for at least 2 months prior to applying for the yearly extension. After the approval of your extension, the amount should stay for a minimum of 3 months, and for the rest of the year, the balance should not fall below 400,000 THB.
