Xin chào, I see there have been some similar questions on this matter. I would like to clarify, I am flying in from KL on Malaysia Air and leaving the same day on Japan Airlines. I will not leave the airport but in order to pick up my luggage and switch planes will I need any special Visa to Vietnam? I assume I need to go through immigration to claim my bags. Thank you.
You are not required to apply for have a Vietnam visa as long as you just plan to stay inside the airport for transiting purpose.
You are only required for visa to Vietnam if you want to clear immigration and make a short trip to the city.
We hope this information is clear to you.
Wish you all good things.
