What is the best way for an expat on a DTV visa to open a bank account in Thailand?

Expats holding a DTV visa often face challenges opening bank accounts in Thailand. Several commenters suggest starting with a residence paper, as banks require this for account creation. Many recommend going through agents, especially in Pattaya, to expedite the process, with costs ranging from 5,000 to 16,000 baht depending on nationality. It is common to face rejections from banks, and experiences vary widely across different branches and bank types. Some suggest certain banks like Bangkok Bank and Krung Thai Bank might be better options, but persistence is key.
