I have booked return flight after a few month as I want to travel to other Asian countries after the 30 days exempt visa , but have not booked those other trips yet . Does the return tiket must show exact 30 days when I get my stamp ? So is better to book ahead of time any other tickets ? Or can I book any other links ?
TLDR : Answer Summary
When entering Thailand with a 30-day exempt visa, you do not necessarily need to provide a return ticket showing exactly 30 days. Instead, it's essential to have proof of onward travel, which can be any ticket to a neighboring country or a reservation from a travel service that offers temporary flight holds. Booking your onward flight ahead of time can be helpful, but it is not a strict requirement.
