Do I need to show proof of 400k in the bank for my first 90-day report after a Non-OA annual extension?

When filing your first 90-day report after an annual extension based on a Non-OA visa, it is typically not required to show proof of the 400,000 baht still being held in your bank. The initial proof of funds (800,000 baht) is assessed during the annual extension application process. However, it's advisable to check the latest immigration regulations as guidelines can change, and always confirm with your local immigration office for the most accurate information.
