Switching passport at Vientiane airport to get visa on arrival ?
Does anyone know if Laos immigration at Vientiane airport cares or not that you have a Thai stamp out of Thailand in your passport when you ask to make the Tourist visa at the Laos immigration?
Is it possible to switch passport without any problem?
I mean can I go out of Thailand stamping out one passport and getting in Laos stamping in with another passport without having problem ?
Is it better to fly from Suvarnabhumi in case so you can say you were in transit in Bangkok from another country so you don't have any Thai stamp?
Or is it OK to fly from Don Mueang because Laos doesn't care to have the stamp out?
Thanks for your advice/answers.
