If you want to switch banks, it’s allowed as long as you never let your balance fall below the required minimum and can show a continuous trail of funds. The safest plan is to transfer during the period when your balance is only required to stay above 400,000 THB (after the 3-month post-renewal window). Start by opening your new account, transfer 400,000 THB first while keeping at least 400,000 THB in the original account, then after a few weeks transfer the remaining amount so the new account holds the full 800,000 THB. Make sure the funds in the new account have been there for at least 2 months before your next renewal.
Keep all transfer slips, bankbooks, and letters to prove the money stayed under your name and within Thailand. With that documentation and proper timing, immigration will accept the new account without affecting your visa status.
We also offer support in case this is too complex, or you would us to handle everything.
