Do Visa Runs Work with an E-Visa?

Updated August 13, 2026

Visa run on a Vietnam e-visa: single vs multiple entry rules explained - saigonvisarun.com

You can do a visa run on an e-visa. Millions of travelers in Vietnam do exactly that every year, and for people based in Saigon the trip usually means a same-day run to Moc Bai. But there is one rule you need to understand before you book anything, because getting it wrong can leave you on the Cambodian side of the border with nowhere to sleep.

The rule is about entry count, not validity. A single-entry e-visa is used up the moment you leave Vietnam. Walk out at Moc Bai on a single-entry e-visa and you have spent your only entry; to come back in you need a brand new visa. A multiple-entry e-visa, on the other hand, lets you cross out and back in as many times as you like while it stays valid, which is exactly what a border run asks of it.

So the short answer to "do visa runs work with an e-visa?" is yes, with a catch: it works automatically on a multiple-entry e-visa, and it works on a single-entry e-visa only if you apply for the next e-visa before you leave. This guide walks through both cases, what the border run looks like at Moc Bai, what it costs, and the mistakes that get people refused re-entry. The management rules around e-visas are tightening too: Decree 286/2026 takes effect September 15, 2026, and our explainer of the new decree covers what actually changes for e-visa holders.

One line to remember: a visa run never refreshes the e-visa you already hold. It either uses a new one (single entry) or re-uses the one you have (multiple entry). Plan for whichever you bought.

How the Vietnam E-Visa Works

Vietnam's e-visa is an online visa you apply for through the official immigration portal, evisa.xuatnhapcanh.gov.vn. You upload a passport photo and a scan of your passport bio page, pay the fee by card, and wait. On approval you download a PDF and either print it or save it on your phone, because immigration will want to see it when you enter.

Since August 2023 the e-visa has been available to citizens of every country and territory, so the old 40-country list no longer matters. The key specs:

Validity: up to 90 days from your intended entry date.
Entry type: single entry or multiple entry, you choose at application.
Fee: USD 25 for single entry, USD 50 for multiple entry, paid online and not refunded if the application is rejected.
Processing: about 3 working days, sometimes faster, occasionally slower around holidays.
Entry points: all 42 international border gates, including 13 airports, 16 land crossings, and 13 seaports. Moc Bai is on the land list, so an e-visa works for a border run.

The stay itself is up to 90 days per entry. For most people the practical effect is simple: a 90-day single entry means you can stay three months and then leave for good, while a 90-day multiple entry means you can come and go for three months without ever touching the immigration website again.

Watch the rejection reasons. Fuzzy photos, passport scans with glare, and mismatched names are the usual causes, and the fee is gone either way. If you have an upcoming visa run, apply early enough that a rejection leaves time for a second attempt.

The Rule That Trips Everyone Up: Entry Count

Here is the misunderstanding that causes most of the trouble at Moc Bai. People treat their e-visa like a membership card that a border run "renews." It is not. An e-visa is a permission to enter Vietnam a fixed number of times within a fixed window, and a border run is just you using one of those entries.

A single-entry e-visa gives you one entry, period. You enter, you stay, and the visa is spent. If you then leave Vietnam and try to walk back in on the same visa, immigration will not stamp you. The officer will point out that your entry allowance is used up, and you will be standing in the arrivals hall at Moc Bai with no valid way back into the country.

A multiple-entry e-visa gives you as many entries as you need during its validity. Exit and re-enter ten times in three months if you want; each crossing is permitted. This is why the multiple-entry option exists, and it is the right choice for anyone who knows they will leave Vietnam and come back while the visa is live.

The other thing to know: validity and stay are two different numbers. Validity is how long the visa is good for, up to 90 days from your intended entry date. Stay is how long you can remain per entry, also up to 90 days. A border run on a multiple-entry e-visa does not extend either number. It simply lets you keep using the visa you already paid for.

Quick check before you book a run: open your e-visa PDF and look at the line that says "single" or "multiple." That single word decides whether your border run is a routine trip or a problem waiting to happen.

Visa Run on a Single-Entry E-Visa: The New-Visa-First Plan

If you hold a single-entry e-visa and you want to stay longer, a border run still works. The trick is that the run must be powered by a brand new e-visa, not the one you entered on. You apply for the next e-visa before you leave Vietnam, then use it to come back in after the run. The old visa is finished the moment you exit.

Here is the sequence that works:

About a week before your run, apply for a new e-visa on evisa.xuatnhapcanh.gov.vn. Choose multiple entry this time if you think you might run again.
Set the intended entry date to the day you plan to cross back into Vietnam after the run. The new visa's 90-day validity starts from that date.
Wait for approval and download the PDF. Three working days is the official processing time, so build in a buffer.
On run day, exit Vietnam at Moc Bai with your current passport. Your exit stamp closes out the old visa.
Turn around and re-enter Vietnam presenting the new e-visa. You get a fresh 90-day stay.

Two warnings. First, do the run before your current visa expires. If you exit after expiry, you are overstaying, and the fine runs about 500,000 VND per day, collected when you leave. Second, never try to re-enter on the old single-entry e-visa as a fallback. It is spent, and the officer at the desk will not bend the rule because you have a flight tomorrow.

Worst case scenario: you exit on a single-entry e-visa with no new visa approved. You are now in Cambodia with a passport that cannot get you back into Vietnam, and the fastest fix is a new e-visa application plus a few days in Bavet or Phnom Penh. That is how a cheap border run turns into a hotel bill.

Visa Run on a Multiple-Entry E-Visa: You Rarely Need One

With a multiple-entry e-visa, the honest advice is that you probably do not need a visa run at all. You already hold permission to leave Vietnam and come back as many times as you like for up to 90 days. The border run exists to reset an expiring stay, and a multiple-entry e-visa resets itself.

That said, runs still happen for other reasons. People cross to Moc Bai to visit the Bavet casino complex, to shop the duty-free, or simply because a friend is going. If you do the trip, the border procedure is the same as for anyone else: exit stamp on the Vietnamese side, walk the 200 meters to the Cambodian post if you want a Cambodia stamp or a visa on arrival, then come back and get your fresh Vietnam entry stamp.

On re-entry, your stay clock restarts within the limits of the visa. The one thing to check before you leave is that your e-visa validity has not run out. If the visa itself has expired, the multiple-entry privilege expires with it, and you are back in single-entry territory: you would need a new e-visa before re-entering.

For most expats the practical move is simple. If you expect to do even one border run or a short trip to Cambodia, Laos, or Thailand during your three months, buy the USD 50 multiple-entry e-visa. It costs USD 25 more than the single-entry version, and it removes the entire class of problems this page is about.

Rule of thumb: single entry for a one-way visit, multiple entry for anyone who might cross a border during the stay. Tourists rarely need multiple entry. People living in Saigon usually do.

The Run Day at Moc Bai, Step by Step

Moc Bai is the closest Cambodia border crossing to Saigon, about 80 to 85 kilometers northwest of the city on National Highway QL22, roughly two hours by car. It opens at 6:00 AM and closes at 10:00 PM daily with no lunch break, which makes same-day runs easy. A typical e-visa border run looks like this:

Leave Saigon early. A 6:30 or 7:00 AM departure gets you to the border before the tour buses pile in around mid-morning.
Exit Vietnam. Present your passport at the Vietnamese departure counter and get your exit stamp. This is where your old single-entry e-visa gets spent, or where your multiple-entry e-visa simply records another exit.
Walk to the Cambodian side if you want a Cambodia entry stamp or a visa on arrival. For a pure visa run, many people skip Cambodia entirely and turn around at the Vietnamese exit gate. No Cambodia visa is needed for a same-day turn.
Re-enter Vietnam. Hand over your passport plus your new e-visa (printed or on your phone) if you are entering on a fresh single-entry e-visa. Officers at Moc Bai see visa runners all day and the process takes five to ten minutes on a quiet morning.
Drive home with a fresh entry stamp and, if you planned it right, a fresh 90-day stay.

Arrive before early afternoon at the latest, because the border gets busier toward evening and the road back to Saigon is worse after dark. If your e-visa expires today, do not attempt the run; you would be exiting in overstay, and the fine is not worth it. Cross the day before, or better, two days before.

What It Costs: E-Visa Fees vs the Run Itself

People often mix up the visa fee and the run cost when they budget. They are separate bills. Here is the full picture in one table:

Item	Cost	Notes
E-visa, single entry	USD 25	One entry, up to 90 days, paid online
E-visa, multiple entry	USD 50	Unlimited entries within validity
Shared van / bus to Moc Bai	500,000 to 800,000 VND	Round trip from Saigon
Private car visa run	from about 1,500,000 VND	Door to door, driver waits at the border
Cambodia visa on arrival	USD 30 to 35	Only if you enter Cambodia; skip for a stamp run
Border fees	0 VND	Exiting and re-entering Vietnam costs nothing

Run the math for a single-entry holder who wants another three months: USD 25 for the new e-visa plus transport, or roughly USD 45 to 70 all in for a no-frills shared ride. A private car service costs more but removes the planning: the driver handles the border logistics and waits while you stamp out and back in, same day, door to door.

Compare that with the alternative of doing nothing. An overstay fine runs about 500,000 VND per day, the clock starts the day after your visa expires, and it is collected at the border when you finally leave. One unplanned week of overstay costs more than the entire e-visa plus a private car run.

Frequently Asked Questions

Can I do a visa run on a single-entry e-visa?

Yes, but only with a new e-visa in hand. A single-entry e-visa is used up when you exit Vietnam, so you apply for the next e-visa before the run, set its intended entry date to the day you return, and present it when you re-enter at Moc Bai.

Does a visa run reset my e-visa?

No. A border run never extends the visa you already hold. On a single-entry e-visa it spends your only entry, and on a multiple-entry e-visa it just lets you use the entries you already paid for. A fresh stay comes from a new visa or a fresh entry on a still-valid multiple-entry visa.

Can I apply for a new e-visa while I am still in Vietnam?

Yes. Applications are submitted online from anywhere, and people routinely apply for the next e-visa while sitting in Saigon. Set the intended entry date to your border run day and give yourself at least a week for processing and any rejection do-over.

Does Moc Bai accept e-visas?

Yes. Since August 2023 e-visas are valid at all 42 international border gates, and Moc Bai is one of the 16 land crossings on the list. You can exit and re-enter there on an e-visa.

What happens if my e-visa expires before my visa run?

You are overstaying from the day after expiry, and the fine is about 500,000 VND per day, collected at exit. Do the run before the expiry date, ideally two or three days early in case of traffic or long queues.

Should I buy a single-entry or multiple-entry e-visa?

Single entry for a one-way visit. Multiple entry if you might cross a border during your stay, which covers anyone planning a visa run, a weekend in Cambodia, or a trip to Laos or Thailand. The extra USD 25 buys total freedom from re-entry paperwork.

Want the Border Part Handled for You?

A private car visa run from Saigon to Moc Bai gets you out, stamped, and back in the same day, with a driver who knows the border routine and waits while you cross. You just bring the right e-visa. Door to door, air conditioned, no bus schedules.
