A Vietnam transit visa is required for foreign travelers who must pass through Vietnam immigration during a layover or connecting flights. If you remain inside the airport transit area of the international terminal at major airports such as Tan Son Nhat airport or Noi Bai airport, and your layover is under 24 hours with confirmed connecting flights, you normally do not need a visa.
However, if you need to leave the transit area, collect luggage, or change airlines requiring immigration clearance, you must obtain a Vietnam transit visa or another valid Vietnam visa before entry. Understanding these rules helps travelers avoid boarding issues and delays during airport transit in Vietnam.
Vietnam transit visa rules for international travelers
A Vietnam transit visa is issued to foreign travelers who stop in Vietnam temporarily while traveling to another country.
This situation usually occurs when passengers have connecting flights or layovers at Vietnamese international airports.
Common transit airports include:
Tan Son Nhat airport (Ho Chi Minh City)
Noi Bai airport (Hanoi)
Da Nang international airport
Cam Ranh international airport
Based on our daily work with the Vietnam Immigration Department, not all transit passengers need a visa.
The requirement depends on three key conditions.
Situation
Visa required
Staying inside airport transit area
No
Layover under 24 hours with same airline
Usually no
Collecting luggage and re-checking flights
Yes
Changing airlines requiring immigration clearance
Yes
Leaving the airport during layover
Yes
A critical detail most applicants overlook is that Vietnam immigration rules focus on whether you pass the immigration booth, not simply how long your layover lasts.
If you do not cross immigration control, you normally do not need a visa.

Do you need a visa for a layover in Vietnam airports?
Many passengers transit through Vietnam airports without realizing the immigration requirements.
From our daily work with the Vietnam Immigration Department, the rule is simple: You do not need a Vietnam transit visa if all the following conditions are met.
Visa-free transit conditions
Travelers can transit visa-free if they:
Have a layover under 24 hours
Remain in the designated transit area
Have confirmed connecting flights
Possess a valid ticket to the final destination
Have a valid visa for the destination country (if required)
Additional required documents include:
Passport valid at least 6 months
Confirmed boarding pass or ticket
Proof of onward travel
In this case, passengers remain inside the international terminal transit zone and do not pass through the immigration booth.
This procedure is commonly used by travelers transiting through:
Tan Son Nhat airport
Noi Bai airport
Airlines typically guide passengers through the airport transit lane, avoiding entry into Vietnam.
Example scenario: Visa-free airport transit
A traveler flying: London → Ho Chi Minh City → Sydney
If:
Both flights are connecting flights
Luggage is checked through
Passenger stays inside the transit area
No Vietnam transit visa is required.
Situations where a visa becomes necessary
A visa is required if you need to:
Pass through the immigration booth
Leave the international terminal
Collect luggage and check in again
Stay overnight outside the airport
Change airports in Vietnam
Based on our experience handling thousands of transit cases, changing airlines is the most common reason travelers unexpectedly need a visa.
Many airlines do not transfer luggage between separate tickets.
Passengers must:
Enter Vietnam
Collect baggage
Re-check luggage
This process requires passing Vietnam immigration, which means a visa is required.
Foreign visitors staying overnight in Vietnam must report their residence. Hotels usually handle this automatically.
If you stay at a private home, the host must report to the local police authority. Failure to declare temporary residence can result in administrative penalties.
Our experienced consultants ensure a smooth, time-saving, and risk-free process.
Located in Hanoi, this airport is the second-largest international gateway. Transit passengers can remain inside the international terminal without clearing immigration if eligible.

Northeast Asia
Southeast Asia
Many travelers transit through Da Nang when flying between Japan, Korea, and Southeast Asia.
