Laos visa at Luang Prabang airport
I will arrive at Hanoi Noibai Airport (Vietnam) on Friday October 11 at 08:20 in the morning and once there I have a 12:15 flight from Hanoi to Luang Prabang (Laos). I have already the visa for Vietnam. But I need to know if when I take the plane from Hanoi to Laos I need a visa for Laos.
On the other hand, I need to know if when I come back from Luang Prabang airport to Hanoi again on October 12 the Visa I have already for Vietnam is good or perhaps I would need to get a new Visa for Vietnam in Noibai Airport.
