My wife and I's Non-O retirement extensions with Re-entry permits expired on 01/07/2025. We will return to Hua Hin and reapply for the replacement in mid-September 2025. Our required Thai bank balances (each) of 800,000 Baht or more have remained intact for more than a year now, and all other personal details are still the same. Can we lodge the applications ourselves when arriving in Thailand? Please help.
