What happens when you leave Thailand after 6 months on a Muay Thai visa and return?

When you leave Thailand after holding a Muay Thai visa and then return, there are generally no additional requirements to show proof of your next 6 months of gym sessions. Upon re-entering, you will receive a new 180-day stamp. Many individuals with this visa have reported re-entering Thailand multiple times without being asked for extra documentation, such as proof of gym sessions.
