Are there any differences in visa exemptions when entering Thailand through Chiang Rai, Chiang Mai, Bangkok, or Don Mueang airports?

The entry point into Thailand, whether Chiang Rai, Chiang Mai, Bangkok, or Don Mueang, does not significantly affect the visa exemption process. All travelers may be asked to provide proof of funds, onward travel, and hotel bookings at any entry point. However, experiences vary, with some suggesting that smaller airports like Chiang Rai may be more relaxed compared to the busier Bangkok airports.
