Can I open a Thai bank account while on a tourist visa?

Opening a Thai bank account on a tourist visa can be challenging but is possible. Many recent experiences suggest that different banks have varying requirements. While some banks insist on a work permit, others may only require a passport and proof of residence, such as a lease agreement or a letter from immigration. Personal recommendations include visiting popular banks in tourist areas or going with a Thai friend who has an account at the branch. It's advisable to persistently try different branches, and bringing cash can also help in facilitating the process.
