Hi everyone,

I'm visiting Thailand I'm January, flying into Bangkok and flying out of Bangkok 10 weeks later. Looking to go to northern Thailand for my first 3 weeks then to Vietnam and Cambodia. And back to the south of Thailand before I fly home.

Is it possible to enter on a 30 day visa, spend around 3-4 weeks in Cambodia and Vietnam, then re enter on a 30 day visa? Is this considered acceptable?

Would I need to book a flight to vietnam now to demonstrate I'm leaving Thailand? Or would the flight 10 weeks later be okay?
