Hello, We are Dutch citizens. We arrive in Hanoi with the plane. Then we want to travel further to Cambodia en Laos. Then we go by land back to Vietnam. In total we are staying in those three countries for 33 days. I know what kind of visa I need for Cambodia and Laos. But what do I need for Vietnam? And how can I arrange it? At first we arrive with plane in Hanoi and after 32 days we arrive in Vietnam over land.
