Quick summary
If your bag is checked through to Phnom Penh on one ticket, you can stay airside at Ho Chi Minh City for up to 24 hours without a Vietnam visa. If you must collect and re-check it on separate tickets, you pass through Vietnamese Immigration and need an entry document — a US$25 e-visa from evisa.gov.vn unless your nationality is visa-exempt.
Vietnam issues no separate airport transit visa, and the e-visa fee has been US$25 single-entry since 1 April 2026. The entry port on an approved e-visa cannot be changed afterwards.

On 8 October 2026, a traveler whose bag is not tagged through to Phnom Penh still has to pass through Vietnamese Immigration at Ho Chi Minh City to collect it and check it in again. That walk turns a short connection into an entry into Vietnam. The airline checks the document before boarding at the departure airport. The check does not wait until Saigon.
For travelers from North America, Europe and Australia and New Zealand, the practical question is which of the two tickets they hold.
A through-ticket and separate tickets can produce very different connections. Vietnam Knowledge’s transit guide (17 May 2026) draws the line at whether the traveler enters Vietnam.
Why separate tickets can get you denied boarding
Two booking references are the trigger. Vietnam Knowledge’s guide states the consequence plainly: separate tickets with baggage to collect and re-check mean you will exit Immigration, which requires an entry document. The airline asks for it at check-in. A refusal therefore comes before you reach the gate in Ho Chi Minh City.
A through-ticket keeps you inside the transit area. Budget carriers sell the protected version of the same connection: AirAsia’s Fly-Thru connections from Australia to Cambodia are the label to look for.
This is not unique to Vietnam. Wherever a separate ticket forces you to collect a bag, you enter the country to do it, the same logic behind a Delhi stop en route to Bhutan that requires an Indian visa.

Airside vs landside: when you can transit Vietnam visa-free
The test is the Immigration line, not the clock. Vietnam Knowledge’s guide (17 May 2026) sets out the airside case: stay airside, do not exit Immigration, and connect within 24 hours with an onward boarding pass, and no visa is required. Leaving to change terminals or to leave the airport also counts as an entry. Travelers who must enter use an e-visa, or visa-free entry if their nationality qualifies.
For layovers of 24 to 72 hours, or any layover where you need to exit, the same guide says you should hold a valid entry document before travel rather than trying to arrange one on arrival.
The airside time limit is not permission to leave. A 20-hour connection with a bag tagged to Phnom Penh is visa-free; a 90-minute connection on two tickets is not, because the bag still has to be collected and re-checked.
The Vietnam e-visa: current fee, processing, and official portal
The fee is US$25 for a single-entry e-visa and US$50 for multiple entry, under Circular 28/2026/TT-BTC, in force since 1 April 2026. The e-visa runs up to 90 days, single or multiple entry.
Official processing takes 3 working days after the Immigration Department receives a complete application and the fee. It counts Monday to Friday Vietnam time (GMT+7), excluding public holidays. Payment is online by card, and the fee is not refunded if the application is refused.
Vietnam’s official e-visa portal is the only place the visa is issued. The lookalikes are explained in the official Vietnam e-visa site and the lookalikes that copy it.
Cambodia runs a separate system. Its own e-visa is applied for at Cambodia’s official e-visa site, where the single-entry tourist type costs US$30, is valid for entry within three months of issue and allows a 30-day stay.
Documents and entry point: what to get right before applying
The passport must be valid for at least 6 months after arrival in Vietnam. The e-visa is issued against the passport number typed into the form. Two images are required: a clear photo of the passport data page and a recent 4x6cm portrait against a white background, without glasses.
For a Ho Chi Minh City connection, the entry point is Tan Son Nhat International Airport (SGN). The form also asks for an email address and entry and exit ports.
Since April 2026, Tan Son Nhat has also run a digital pre-arrival information declaration, since extended to other airports. It is not a visa application and does not replace one. It is an extra requirement, not a substitute.
Verify your visa details before travel
An approved e-visa names one entry port, and that port cannot be changed after issue. A different Vietnamese airport or a land crossing means a new application, not an amendment. A port on the visa that does not match the port actually used means the document does not cover the arrival.
The e-visa is accepted at 83 Vietnamese ports as of October 2026. That total includes 17 airports, 27 land and rail border gates and 39 seaports.
Long Thanh and Gia Binh airports join the list only when they open. That distinction matters for a connection through a smaller Vietnamese airport.
Where the exemption list changes the answer
The e-visa fee, passport-validity rule and processing time are the same for every traveler. What changes with the passport is whether a landside connection needs an e-visa at all.
North America. US and Canadian passports are not on Vietnam’s visa-exemption list. A landside connection needs an entry document: the single-entry e-visa, or multiple entry for travelers who plan to leave and re-enter Vietnam.
Europe (including the UK). Vietnam’s visa-exemption list, updated 15 July 2026, grants 45 days visa-free to UK passport holders and to a European list that includes France, Germany, Italy, Spain and the Netherlands. Not every EU member appears on it, so check your own nationality rather than your passport’s colour.
Australia and New Zealand. Neither passport appears on the exemption list. Australian and New Zealand travelers therefore need the e-visa for a landside connection, at the same single-entry price as everyone else.
Fix the plan before you pay
The decision point is the week you book, not the night before you fly.
- Fix your dates before you pay: the form asks for planned entry and exit dates and a Vietnam address; your first hotel is fine. Apply at evisa.gov.vn before you fly, not while waiting to see whether the airline notices.
- Ask about through-checking: with two booking references, ask the first carrier whether it will tag your bag to Phnom Penh; if it will not, plan for a landside connection and the entry document that goes with it.
- Ask for both boarding passes at check-in: the visa-free airside route depends on holding an onward boarding pass for a connection within 24 hours. Check eight fields against your passport and itinerary before you fly: full name, passport number, date of birth, nationality, entry date, expiry date, entry type and entry port. For a smaller Vietnamese airport, check the accepted-port list before you pay.
- Watch: a delay that pushes your connection past 24 hours moves you into the bracket where Vietnam Knowledge’s guide says an entry document is required before travel.
A date or passport-number change after approval also starts the process again. That is why the check belongs in the week you book.

Questions? Answers.
Do UK passport holders face the same Vietnam transit visa requirement?
Not for a landside connection. Vietnam’s visa-exemption list, updated 15 July 2026, gives UK passport holders 45 days visa-free, so a UK traveler who has to collect and re-check a bag can enter on the exemption instead of an e-visa. The airside rule is the same for every nationality: stay inside the transit area with an onward boarding pass and no visa is needed.
Can I apply for the Vietnam e-visa on arrival if I forgot before departure?
No. The e-visa is applied for online before travel, and Vietnam issues no separate airport transit visa at the airport. A traveler who reaches a departure airport without an entry document for a landside connection faces two options: a through-ticket, or a later departure once the e-visa is approved.
What if my connection time in Ho Chi Minh City is only 90 minutes?
Connection length does not change the requirement; the ticket does. On separate tickets you still have to clear Immigration, collect the bag, re-check it and clear security, so the layover has to cover that whole sequence. On a through-ticket, a 90-minute connection stays airside and needs no visa.
Does this rule apply to connections through Hanoi instead of Ho Chi Minh City?
Yes. The test is whether you pass through Vietnamese Immigration, and it applies at any Vietnamese gateway. The practical difference is the entry port: declare the airport you actually arrive at, because the port on an approved e-visa cannot be changed after issue.
If I have a Vietnam e-visa, can I leave the airport during a long layover on a through-ticket?
Yes. Leaving for the city is an entry into Vietnam, and an e-visa is an entry document, so a through-ticketed passenger can step out and return for the onward flight. Without an entry document, the visa-free exemption only covers staying inside the transit area.
