Immigration officers may request documents such as a passport with sufficient validity, proof of onward travel, accommodation details, and confirmation of the Thailand Digital Arrival Card (TDAC) where applicable. Larger airports like BKK and HKT may apply more detailed checks due to higher passenger volumes, while regional airports often offer faster processing during off-peak hours.

All international airports in Thailand apply the same national immigration regulations, including:

• Passport validity of at least 6 months
• Thailand Digital Arrival Card (TDAC) submission
• Proof of funds (cash requirement)
• Visa checks based on nationality and purpose of stay

However, larger airports such as Suvarnabhumi (BKK) and Phuket (HKT) may apply stricter or more detailed checks due to higher passenger volumes.
