Normally overseas travelers are
required to have Vietnam visa stamp on passports to enter in Vietnam mainland
except for visa exemption nations.
There are 2 cases which you have
to consider once Vietnam International airport is a stopover only on your way.
In case is that you just transit
at Vietnam airport in a few hours to wait for the next flight and don’t have
intention to move out transit area, you don’t need Vietnam visa.
On the other hand, you need to
obtain Vietnam visa to enter Vietnam mainland. It happens in case is that you
have to wait for the next flight in many hours (about 6 – 8 hours). You would like to travel
Vietnam in short time or find a hotel to take a rest. At this time Vietnam visa
on arrival will be the best solution. You just apply visa online and get
approval letter within 2 working days. We suggest that you should do it before
your departure. Afterwards you will print approval letter and get visa stamp at
Vietnam airport. Certainly you enter Vietnam normally with stamped visa. The
shortest validation length is one month. Of course you must apply this visa
type to enter Vietnam. Please remember that you are allowed to enter and exit
Vietnam whenever you want in the valid period. For instance you enter Vietnam
on the fifteenth of June and exit from Vietnam on the same day.
In conclusion you don’t need
Vietnam visa as you transit at Vietnam international airport and stay in
transit area only.
