I'm planning a trip to Thailand and the neighbouring countries from early September and need some clarification on Visas etc.
My plan is to head to Bangkok to start with then head to Cambodia and Vietnam by train. Obviously I need a Visa when I first arrive in Thailand, but do I need to have proof of a return ticket or proof of onward journey? Also I was hoping to spend a little time in Bangkok to begin with, visit the other countries then head back to Bangkok as a friend might be visiting me while I'm out there. If I've already been stamped with a 30 day tourist visa when I arrived, can I come back into Thailand for a second time?
Appreciate any help with this. Thanks
