Tourist can enter and exit Vietnam at Hanoi, Ho Chi Minh City and Danang airports or at any of its plentiful land borders, shared with Cambodia, China, and Laos. It’s possible to enter Cambodia or Laos from Vietnam and then re-enter without having to apply for another visa. However, you must apply for a re-entry visa before you leave Vietnam. If you do not have a re-entry visa, you will have to go through the whole visa process again. Contact Indochina Tours for visa information assistance.
