Ho Chi Minh City visa run, step by step from the alarm clock to the fresh stamp

The big picture

A same-day loop, and it fits in one long day

Strip away the nerves and a visa run from Ho Chi Minh City is a simple errand. You leave your stamp in Vietnam, cross into Cambodia, and come back with a new one. The border for this city is Moc Bai, about 80 km up QL22, and the whole loop takes one day.

The rough shape of the day: leave before sunrise, drive two hours, clear Vietnamese exit in ten minutes, walk into Cambodia, pay for the visa, walk back, get the new entry stamp, drive two hours home. The border part takes less time than most people expect. The driving is the day.

That is the ideal shape with a private car or the door-to-door shuttle. On the public coach from Ben Xe Mien Dong, add an hour each way and expect to be home mid-afternoon. The sequence of stamps never changes, only the times. Everything below walks through each step in the order you will actually hit it.

Before the run

The checklist, and the one thing that must be done first

The single most important rule of this whole page: your new Vietnam e-visa must be approved before you leave. Without it, Vietnam will not let you back in at Moc Bai, and you will be in Cambodia with a hotel bill and a headache. Check the approval email the night before. Not the week before. The night before.

File the e-visa one to two weeks ahead through the official portal, or let the visa desk handle it. The desk has a useful habit: it submits the application the moment your exit is stamped, so the 90 days line up exactly with your return. If you filed yourself and the application is stuck, the push service from 25 USD moves it along.

The e-visa starts on re-entry, not on approval. Approval might arrive a week before your run, and that is fine. The 90-day clock only starts when the officer stamps you back in at Moc Bai. If you cross before the approval arrives, you are crossing without a visa, and that is the one mistake nobody should make.

No passport photos, no printed forms, no bank statements. For e-visa holders the Vietnam side is a passport-and-scan operation. The Cambodia side wants cash and a form, covered in its own section below.

The drive

Out on QL22 before the city wakes up

The run leaves early for a reason. The passenger checkpoint at Moc Bai never closes, so there is no opening hour to beat. What you are beating is the queue. Tour buses from the city start arriving mid-morning, and the border lanes fill up fast. Leave between 4:30 and 6:00 am and you clear the windows before that wave.

The door-to-door shuttle picks up from District 1, Thao Dien, Thu Duc, and Phu My Hung, in that rough order, so a Thao Dien resident is usually on the road earlier than someone in the city center. The public alternative is the coach from Ben Xe Mien Dong, which costs less and leaves on a fixed schedule, but it is slower and the return bus is the part people get wrong.

The road itself is QL22 the whole way: out through the market sprawl on the edge of Hoc Mon, then open countryside once Tay Ninh province starts. It is a sealed two-lane highway with steady truck traffic, not a scenic route. Coffee stops are common around Trang Bang, and the driver will know where. Plan 2 hours by car or van, 2.5 to 3 hours by coach, and expect the last stretch past the Tay Ninh turnoff to feel longer than the map suggests.

One practical note about the way home. The return drive is the same 80 km, but you hit the edge of Saigon around midday, and the ring road and city entrances get properly busy. Budget the same 2 hours, plus a buffer. The bus and shuttle schedules page has the departure windows for each pickup area if you want the detail.

Step one at the border

The Vietnamese exit: a ten-minute errand

The vehicle pulls into the Moc Bai passenger area and you join the line at the Vietnamese checkpoint. This is the moment first-timers build up in their heads, and it is anticlimactic. You hand over your passport, the officer checks it against the screen, stamps the exit, and hands it back. That is the entire exit procedure. No forms, no questions, no photos, no fee.

The exit stamp is the important one. It closes your current stay on the old visa, and it is the reference the whole run hangs on. Watch the date on the stamp before you walk away. If it looks wrong, point at it and ask the officer to fix it on the spot. Fixing it later from the Cambodian side is a much bigger problem.

What the officers actually check: your passport matches you, it is valid, and you are not on a watchlist. If you have run frequently this year, a quiet officer might ask how often you cross. Answer honestly and simply. There is no rule against visa runs, and nobody is looking to trip you up, but long rambling answers are how people create problems that did not exist.

Once you are stamped, you walk through the gate and across the short no-man's-land to the Cambodian side. It is a walk of a few minutes, past the duty-free stalls and money changers. Do not lose your exit stamp receipt if the officer gave you one; it is your proof you left legally and the desk may ask for a photo of it for the e-visa filing.

Step two at the border

Bavet: the visa counter and the cash rule

Cambodian immigration at Bavet is a short walk from the Vietnamese gate. Unless you already hold a Cambodia visa or an e-visa for Cambodia, you buy one here, on arrival. Most nationalities pay roughly 30 to 35 USD, and the counter takes cash. This is the one point in the whole run where a card is useless and an ATM is not nearby, so carry the cash from Saigon.

The procedure: queue, hand over your passport, pay, wait a few minutes while the officer writes or prints the visa, get the entry stamp, and you are officially in Cambodia. Total time is usually under fifteen minutes outside the mid-morning rush. The Cambodia visa at Bavet page lists the nationality exceptions and the prep that keeps the window short.

Here is where the same-day run splits from the longer trips. For the standard reset, you do not need to go anywhere. Once Cambodia has stamped you in, you turn around, get the Cambodian exit stamp, and head back to the Vietnamese window. You have legally been in Cambodia, which is the whole point. If your plan is an overnight in Phnom Penh or a Laos run, that is the other direction, and the Laos route guide covers it.

Watch the money changers on the walk between the gates. Their rates on USD are fine in small amounts, but you do not need to change anything for a same-day loop. Keep your dollars and your VND separate, count the change from the visa counter, and do not let anyone rush you. Ten minutes of patience here saves an hour of paperwork later.

Step three at the border

Back through Moc Bai on the new e-visa

The return crossing is the mirror image of the exit, with one extra step. Cambodia stamps you out, and then the Vietnamese officer at Moc Bai scans your passport, finds your approved e-visa in the system, and stamps you in. The whole thing takes a few minutes when the queue is short.

This is the moment your new stay begins. The officer's entry stamp is the start date of the 90 days, not the day your e-visa was approved. Check that stamp too. The date should be today. If it is wrong, ask for a correction before you leave the window, because the rest of your stay is counted from that date.

What the officer checks on the way in: your passport, the e-visa match, and your exit stamp from a few minutes earlier. The short gap between exit and re-entry is normal, and officers at Moc Bai see it hundreds of times a day. There is no minimum time you must spend in Cambodia, despite what forum threads claim. Same-day loops are routine at this border.

Keep the printed e-visa or the PDF on your phone until you are home. Hotels in Vietnam often scan it at check-in, and it is the document that proves your stay is legal if anyone asks. The entry stamp in your passport is the proof immigration cares about; the e-visa copy is what everyone else wants to see.

When things go sideways

Four things that actually go wrong, and how to dodge them

Most runs are boring in the best way. But the failures that do happen are predictable, and they all have the same root cause: something was checked too late. Here are the ones worth planning around.

The e-visa is still processing. The classic. If the approval email has not arrived by the morning of the run, do not cross. You will exit fine and then be stuck on the Cambodian side with no way back in. Shift the run by a few days or use the push service, from 25 USD, which the desk runs against the stuck application.

A wrong date on a stamp. Rare, but it happens, and it is always the exit stamp on the way out or the entry stamp on the way back. Check both dates before you step away from the window. An officer will fix a stamp you flag immediately. Nobody can fix it after you drive home.

The officer asks questions. If you have crossed several times this year, expect a mild inquiry about how often you travel. Answer plainly: you are renewing your tourist stay, you have a valid e-visa, you will leave before it expires. There is no ban on visa runs, and the question is routine, not an interrogation. Calm and short beats nervous and chatty.

The return bus leaves without you. This one is specific to the public coach. The Ben Xe Mien Dong route back to the city has set departures, and if you miss the last one, you are finding a taxi for 80 km or a hotel in Tay Ninh. The door-to-door shuttle waits for its own passengers, which is exactly why it costs more. If you take the public bus out, photograph the return schedule before you cross.

First-timers, read this twice: the border staff are not scary, the windows are labeled, the walk between the gates is short, and thousands of people do this exact loop every week. The one decision that matters is the e-visa. Everything else is a queue and a stamp.

What it costs

The 2026 numbers at a glance

Full line-item pricing lives on the cost page. For the step-by-step version, the numbers that matter are these.

The bundle prices beat buying each line separately by 200,000 VND, about 8 USD. The government e-visa fee itself is separate and itemized before you pay, so there are no surprises on the day. If you want the DIY angle, the cheapest visa run guide ranks motorbike, coach, van, and car against each other.
