Hello,
I’m from the USA, I have been thinking about traveling to Thailand this year. I have seen that US travelers don’t need a visa to visit Thailand, but I was wondering if there was anything else I need to take care of so that I am not turned away at the airport?
TLDR : Answer Summary
US travelers do not need a visa for short stays in Thailand but must prepare various documents due to COVID-19. Essential requirements include a Certificate of Entry from a Thai embassy, a 'fit to fly' certificate, a negative COVID-19 test taken within 72 hours prior to travel, proof of booking for quarantine (ASQ) hotels, and travel insurance with coverage for COVID-19. The rules can change frequently, so consulting the Thai embassy's website for the latest information is highly recommended.
