Hey :) me and a freind are going to thailand for a couple weeks then Cambodia, do we need to have proof of leaving the country when we show up?
TLDR : Answer Summary
When arriving in Thailand, it is advisable to have proof of onward travel, especially if you are entering on a 30-day visa-exempt status. Airlines may require this documentation before boarding, so it's prudent to have it ready to avoid any issues upon arrival.
