What are the current requirements for maintaining a retirement visa in Thailand, specifically regarding the 800,000 THB financial rule?

Recent discussions among expats indicate confusion regarding the requirement for maintaining a retirement visa in Thailand, specifically the financial rule concerning 800,000 THB. Many claim that this rule has not changed and has always required the funds to be held for a specific duration. Typically, 800,000 THB needs to be in the account for at least two months prior to application and maintained for three months after. Further, throughout the rest of the year, the balance should not dip below 400,000 THB. Some individuals reported encountering immigration officials who insisted on new requirements, leading to misunderstandings, while others affirmed that the existing rules have been in place for some time. It appears that consistent proof through bank statements is essential, and potential miscommunications may occur due to varying interpretations by immigration officers.
