Is the 20,000 THB cash requirement for entering Thailand a legitimate reason for refusal to enter?

The 20,000 THB cash requirement is a legitimate rule, though it is not always strictly enforced. However, individuals who frequently use back-to-back tourist visas may face increased scrutiny and a higher likelihood of being checked for this requirement. Some travelers, regardless of their financial status, have been turned away if deemed not to be legitimate tourists, with immigration often citing insufficient funds as a common reason for refusal.
