What documents do I need to show when leaving Thailand besides my visa, passport, and return ticket?

When preparing to leave Thailand, you generally need to show your visa, passport, and return ticket. However, it's advisable to have additional documentation, such as accommodation information and possibly your travel insurance. It's also recommended to print out any documentation related to your Thai pass and have a copy of everything you submitted for it. Some travelers also suggest keeping a digital backup of your documents, in case it's needed.
