We would like to summary a normal procedure at the airport as follows:
- landing
- getting the visa at Immigration Checking Point (pass if you already get the visa at Vietnam embassy/consulate)
- checking visa and get the residence stamp at Immigration Booth
- taking the luggagen
Then, if you transit on the same plane, do not leave the isolated area and not need to take the luggage, then you do not have to get the Vietnam visa. Otherwise, you have to apply the visa.
