What is the policy on retaining the ฿400,000 bank balance for a Thai wife/family extension in Bangkok?

The requirement for retaining a ฿400,000 bank balance for the twelve-month extension of a Thai family visa is not strictly enforced in Bangkok after the extension application is submitted. Some immigration offices may allow the funds to be withdrawn immediately, while others may not. Generally, in Bangkok, applicants receive a 21-day 'under consideration' stamp, and there is no strict written policy regarding maintaining the funds during this period. However, it is recommended to keep the funds in the account for a few weeks to avoid any issues.
