Staying longer in Vietnam, and why the answer keeps changing
On this page
A Vietnam visa extension is the one question this site cannot answer cleanly, and the reason is that the rules moved and the guidance online did not keep up. The e-visa now runs up to 90 days with multiple entries, which is a different product from the 30-day single-entry visa most older articles describe. What has not settled is whether you can extend one without leaving.
How long does the e-visa actually give you?
Up to 90 days, and within that period you can enter and leave as often as you like without applying again. That multiple-entry provision is the part people most often do not know, and it changes what a long trip can look like — a side trip to Cambodia or Laos no longer costs a new application.
The e-visa guide covers the application itself, the official portal and the mistakes that get one refused.
Can you get a Vietnam visa extension from inside the country?
On extensions the sources genuinely disagree, and pretending otherwise would be the wrong service. Some visa agencies say plainly that you can extend an e-visa once, for up to another 90 days, from inside the country. Others say equally plainly that nobody extends an e-visa, and that the only route is to exit and apply again.
Businesses that sell the service publish both positions as fact.
Plan as though there is no extension. That assumption costs you a flight if it turns out to be wrong, and it protects you from an overstay if it turns out to be right. Then confirm on the official government portal, or with the immigration department, before committing to anything.
Extensions are the one subject on this site where the answer is "check it yourself", and that is deliberate.
What is a visa run?
Leaving Vietnam and re-entering on a fresh e-visa. It works because the e-visa is applied for from outside the country and re-entry is permitted immediately.
In practice that means a cheap flight to Bangkok, Phnom Penh or Vientiane, a night there while the new visa is granted, and a flight back — 2 days and 2 fares. It is a day of travel and a new fee rather than anything irregular.
| Route | Realistic cost | Notes |
|---|---|---|
| Exit and reapply by air | Two flights plus the visa fee | The standard method |
| Overland to Cambodia or Laos | Cheaper, slower | Confirm the crossing accepts e-visas |
| Extension through an agency | Agency fee on top | Only if extension is available at all |
| Staying past the date | A fine, then worse | Not a plan |
What happens if you overstay?
For a short overstay of a day or two, the airport usually settles it with a fine you pay before flying. That is unpleasant and survivable.
A long one is not routine. Fines escalate, and at length an overstay ends in deportation and a record that complicates coming back. There is no version of this worth risking to save an application fee.
The practical rule: know your exact expiry date, and treat it as a hard deadline rather than a target.
When should you start?
At least 7 days before the visa expires, and more if a holiday falls inside that window — Tet closes immigration offices for the better part of a fortnight. Any immigration process runs on working days, and Tet closes offices for the better part of a fortnight.
Late starts turn an administrative task into an overstay, and that is the single most common way people get caught. Anyone staying to work rather than to travel should read working remotely from Vietnam alongside this, since the visa is the constraint there too. The everyday errands guide covers the laundry-and-haircut half of a long stay.
What does a visa run actually take?
Two days and two fares, if you plan it. Fly out in the morning, apply for the new e-visa from your hotel that afternoon, and fly back once it is granted.
The part that catches people is processing time. The e-visa is not instant, so the honest plan allows for it rather than booking a return flight the same evening. Bangkok, Phnom Penh and Vientiane are all short hops from either end of Vietnam and all have cheap beds.
Do the arithmetic before assuming it is the expensive option. Two budget flights and a night out of the country often cost less than an agency's extension fee, and the outcome is certain rather than contested.
What about working here?
An e-visa does not permit work, whatever purpose you selected on the form. Remote work for a foreign employer sits in a grey area that many people occupy and that nobody official has clarified for visitors; working for a Vietnamese company requires a different permission entirely.
If a long stay is the plan rather than a long holiday, that is a question for an immigration lawyer rather than a travel site. What this page can tell you is the shape of the tourist rules, and their edges.
FAQ
How long can you stay in Vietnam on an e-visa?
Up to 90 days, and the current e-visa allows multiple entries within that period — you can leave and come back without applying again. That is a substantial change from the 30-day single-entry visa most older guidance describes.
Can you extend a Vietnam e-visa from inside the country?
Sources disagree, and that is the honest answer. Some say extension is possible once, for up to another 90 days; others say the e-visa cannot be extended at all and you must exit and reapply. Treat it as not extendable when planning, and confirm on the official portal before relying on either.
What is a visa run in Vietnam?
Leaving the country and coming straight back on a new e-visa. It works because the e-visa is applied for from outside Vietnam, and re-entry is permitted immediately. It is a day of travel and a new application fee rather than a legal grey area.
What happens if you overstay in Vietnam?
A fine, and at length considerably worse. Short overstays are usually settled at the airport with a penalty; longer ones attract escalating fines and can end in deportation and problems re-entering. Nobody should treat an overstay as a routine cost of a late flight.
When should you start an extension or a new application?
Well before the visa expires rather than after. Any process takes working days, and starting late converts an administrative task into an overstay. Give it at least a week, and more if a holiday period falls inside it.
