Can a traveler with a TR visa open a bank account in Thailand, and if so, which bank should they try?

A traveler holding a TR visa can open a bank account in Thailand, although it may require visiting several banks to find one willing to do so. Suggestions include using banks like Bangkok Bank, especially at branches located in tourist areas such as shopping malls. If banks decline, using an agent may be a viable option, generally costing around 4-8,000 baht, with some agents providing services without requiring additional insurance, depending on the traveler's visa validity.
