I am planning on traveling to Thailand, Cambodia, Vietnam and Laos. The idea is to fly to Bangkok, then go to Cambodia -> Vietnam -> Laos and finally go from Laos back into Thailand and fly home through Bangkok again. I will be gone for three months.
Normally i do not need a visa as a Swedish citizen to these countries as i can stay for up to 30 days without. But i am a bit worried about two things.
Will there be problem when i arrive in Bangkok as they see my return ticket is three months later? Or that i dont have one at all if i book it later.
Will there be problem to cross the border back into Thailand from Laos? I have heard that you usually get permission to stay 14 days when you reenter through a land border. But i am not sure if this is still the case?
