Do I need to show 20,000 THB in cash for entry into Thailand from Laos for my family?

Travelers entering Thailand from Laos may be required to show proof of funds, specifically 20,000 THB per person or 40,000 THB for a family of four, particularly when entering on a tourist visa or visa exemption. While this requirement is noted in official guidelines, it is not always strictly enforced and can depend on the immigration officer's discretion. Some travelers have successfully used credit cards or ATM cards as proof of sufficient funds instead of cash.
