Hello! I had an VOA and after that a 30 days extension, so now I could be in Thailand till 13/2. Tomorrow I'll go to Laos for 10 days and after Laos I'll go to Vietnam. But I wanted to take a sleepertrain from Nong Khai (Thailand, just across the border with Laos) to Bangkok to take a flight to Vietnam. I was wondering if I'm allowed to get back in Thailand for the sleepertrain and get again a VOA?
