Leaving Vietnam and Coming Back? When a Single-Entry eVisa Is Not Enough
Short answer: If you leave Vietnam and plan to enter it again, a single-entry eVisa is not enough for both arrivals. Vietnam offers single- and multiple-entry eVisas with a maximum validity of 90 days, but the number of entries and the approved dates are separate limits. Check both against your itinerary before you travel. As of 29 September 2026.

Count the times you will enter Vietnam
The useful question is whether your itinerary takes you out of Vietnam and back in, not how many flights or stops you have within the country. A flight from Ho Chi Minh City to Da Nang stays within Vietnam, so it does not create another international arrival. A side trip from Vietnam to Cambodia followed by a return to Vietnam does.
Mark each arrival into Vietnam after an international border crossing on your itinerary. If the trip has one arrival and then only domestic travel until departure, you are planning one entry. If you leave for another country and come back, plan for a second entry even if the return is only a short stop before flying home. For the general eligibility and application questions around that first entry, see the Vietnam eVisa overview.
What single-entry and multiple-entry eVisas allow
A single-entry eVisa is for one entry into Vietnam. A multiple-entry eVisa can cover more than one entry during its approved validity period. The difference matters at the second arrival: a visa that covered your first entry does not automatically cover a return after you have left the country.
| Your planned trip | Single-entry eVisa | Multiple-entry eVisa |
|---|---|---|
| Arrive in Vietnam, travel domestically, then leave | One entry fits the entry count | More entries than this itinerary needs |
| Arrive, leave for another country, then return to Vietnam | One entry does not cover both arrivals | Can cover the return if the approved dates and other entry conditions also fit |
For example, Hanoi → Da Nang → Hanoi is domestic travel. Hanoi → Cambodia → Ho Chi Minh City includes a second Vietnam arrival. Vietnam's immigration authority describes eVisas as valid for a maximum of 90 days and available for single or multiple entry; that maximum is not a promise that every issued visa lasts 90 days. Check the current official eVisa options for the entry type that matches your trip.
Check the dates and entries on the approved eVisa
Your approved eVisa needs to fit your trip in two ways: its entry type must allow the number of arrivals you plan, and its actual validity dates must cover the relevant arrivals. The government application form treats single versus multiple entry and the valid-from/to dates as separate fields. One cannot make up for a mismatch in the other.
Suppose your document says multiple entry, but your flight back to Vietnam falls after its valid-to date. The extra-entry permission does not extend that date. Conversely, a single-entry document that is still within its date window does not become reusable after you have entered Vietnam and then left. Use the dates and entry type printed on the issued document, rather than the period you requested or the general maximum, when you compare it with your bookings.
If you already hold a single-entry eVisa
First work out whether that entry has been used. If you have not yet entered Vietnam, and your itinerary now includes an exit and return, compare the issued document with both planned arrivals and check the government eVisa portal for the current official options before relying on it for the trip. Do not assume an issued single-entry eVisa can simply be changed to multiple entry.
If you have already entered Vietnam on that single-entry eVisa, plan on the entry being used. Before leaving for a side trip, ask the appropriate Vietnamese immigration authority or consult its current official channel about the permission needed for your return. Do not assume you can solve the return leg by submitting a fresh eVisa application while you are still inside Vietnam, or by showing the same single-entry document at the second arrival. Resolve the return-entry question before committing to the exit.
Before you leave and return
Put your international legs next to the issued eVisa. Identify the first Vietnam arrival, every exit, and any later arrival; then check the printed entry type and validity dates against those arrivals. Place the eVisa beside the passport you will travel with and compare the identifying details shown on both. If they differ, check current official guidance to resolve the discrepancy before relying on the document. A valid passport and a border gate designated for eVisa entry or exit are separate checks, so confirm that your planned crossing is on the immigration authority's eVisa information page.
This is especially useful when the side trip is short. The calendar may show only a day away, but the return is still another entry. If the entry count or printed dates do not cover that return, you cannot rely on the issued eVisa for the second arrival. Check the current government portal and the applicable immigration guidance before you leave; the Vietnam eVisa overview covers the broader application context.
FAQ
Does a flight from Ho Chi Minh City to Da Nang count as another entry?
No. Both cities are in Vietnam, so that domestic flight does not involve leaving and reentering the country. Count an additional entry when your route takes you across an international border and back into Vietnam.
If I visit Cambodia and return to Vietnam, can I use the same single-entry eVisa?
Not for both arrivals. Returning from Cambodia is a second Vietnam entry, while a single-entry eVisa covers one. Check the current official route for permission that fits the return leg, including its dates and the border gate you plan to use.
Does a multiple-entry eVisa give me a new 90 days every time I enter?
No. The 90 days is the maximum eVisa validity described by Vietnam's immigration authority, not a fresh period added at each arrival. The valid-from and valid-to dates on your approved eVisa still govern your return.
Can I change an already-issued single-entry eVisa to multiple entry?
Do not assume that an issued document can be changed. Check its status and the current options through the official eVisa portal or the appropriate Vietnamese immigration authority before planning a second arrival. If you have already used the entry and remain in Vietnam, seek the current official route for your return before leaving.
