Do you need to show 500,000 THB when re-entering Thailand after a 6-month visa?

The requirement to show 500,000 THB upon re-entry into Thailand after a 6-month visa depends on the immigration officer's discretion. Generally, it's not necessary to prove you have this amount when re-entering, as this amount is primarily a requirement for visa applications or in-country extensions. Instead, it is advisable to carry at least 20,000 THB in cash, along with proof of accommodation and an onward flight. Different opinions exist, but the consensus is that showing the full 500,000 THB is not typically required.
