Do I need to show a hand-drawn map for a Non-O retirement visa extension in Thailand, and how detailed should it be?

The process of extending a Non-O retirement visa in Thailand requires you to maintain a bank balance of 800,000 THB two months prior and three months after the application, which can be adjusted to 400,000 THB for the remaining eleven months. This requirement applies to every extension, regardless of how many years you have been extending your visa. Regarding the documentation, a hand-drawn map showing your address is needed, although the required detail can vary by immigration office. Experiences shared by others suggest that a simple drawing suffices, but it's best to verify with your local office.
