What are the requirements for maintaining a 500k baht balance for Thai visa applications?

To meet the 500k bank balance requirement for a Thai visa, the current balance must be at least 500k baht at the end of each month for three months. It is not strictly required to maintain this amount throughout the month; as long as you end each month with a balance of 500k, that should typically suffice. Some embassies, like the UK, are less strict, allowing for fluctuations in balance as long as the final balance is 500k baht.
