Can I do a visa run from Ho Chi Minh City by motorbike?
Yes — it's the cheapest DIY option. Moc Bai is about 80 km and 2 hours from central Saigon up National Highway QL22, and a round trip costs only 100,000–150,000 VND in fuel (or 150,000–250,000 VND for a day rental). You still pay the same Cambodia visa and border fees, and you must leave early enough to clear both checkpoints and ride back before dark. Our shared van costs more but handles the driving, the queues, and the paperwork, so you can relax instead of watching for truck traffic on QL22 all day.
What is the cheapest way to do a visa run from Ho Chi Minh City?
Riding your own motorbike is the cheapest at roughly 1,000,000 VND all-in including fuel and a Cambodia visa. Without a bike, the public bus from Ben Xe Mien Dong (Binh Thanh district) toward Tay Ninh and Moc Bai takes 2.5–3 hours and costs about 200,000 VND round trip — but the last bus back leaves in the afternoon, so border delays can force an expensive xe om ride home. Our 2,000,000 VND shared van seat sits above those DIY options but includes a fixer who queues for you, which is what makes same-day timing reliable. See the full cost breakdown on our cheapest visa run from HCMC page.
Do I need to print my Vietnam e-visa before crossing Moc Bai?
Yes — bring a printed copy of your approved e-visa plus your passport. Immigration at Moc Bai scans the QR code on the approval page and stamps your passport; a photo on your phone is a backup, not a substitute. Print two copies: one for the Vietnam side and one to keep with your Cambodia entry papers, and keep the PDF saved offline in case you need to show it again.
Can I use a visa-on-arrival (VOA) letter to enter Vietnam at Moc Bai?
No. Vietnam's visa-on-arrival letters are only valid at international airports — at Moc Bai you must hold an e-visa, a visa issued by a Vietnamese embassy, or a visa-exemption stamp. If you already paid for a VOA letter, don't waste the trip: our visa desk can file a 90-day e-visa (US$25 single entry) so you cross legally at the land border instead.
What currency should I bring for fees at the Moc Bai border?
Bring US dollars for the Cambodia visa-on-arrival (US$30–35 in cash plus a photo) and Vietnamese dong for any Vietnam-side fees and incidentals. Both currencies are accepted at the official exchange counters at the gate, but rates from touts are poor and shortchanging is common. Carry small bills — US$20s and 100,000–200,000 VND notes — and keep your main cash hidden until you are back in the car.
What happens if I'm denied re-entry to Vietnam after crossing to Cambodia?
Denied re-entry is rare and almost always stems from an overstay, a blacklist record, or arriving on a visa type you do not actually hold. Before you leave Saigon we verify your stamps, visa validity, and overstay history precisely to avoid this. If it ever happens at the gate, stay calm: you can wait in Bavet while our fixers check your records and escalate, or contact your embassy for a replacement visa.
How long is a Cambodia visa obtained at Bavet valid for?
The Cambodia visa-on-arrival at Bavet is single-entry and valid for 30 days — long enough for a border run, but it expires the moment you leave Cambodia back into Vietnam. If you plan several border runs in a short period, tell us: we can coordinate Cambodia e-visa applications or advise on multi-entry options so you do not pay the visa-on-arrival fee repeatedly.
Can I take a flight the same day as my visa run?
Don't book one. The full run takes 11–12 hours, returning to Saigon around 17:00–18:00, and border queues can push that later. The only safe way to fly the same day is a red-eye after 22:00 — and even then a border delay makes it stressful. Book flights for the next day, or message us and we'll schedule the earliest pickup so you maximize your buffer.
What should I do if I overstay and miss my scheduled run?
Don't ignore it. Under Decree 282/2025, an overstay of under 16 days costs roughly 500,000–2,000,000 VND payable at the border, while overstays of 16 days or more require a visit to the immigration office first, with fines rising in brackets up to 30,000,000–40,000,000 VND for overstays of a year or more. Message us on WhatsApp immediately: we'll tell you whether to pay at the gate on run day or fix it at immigration first, and we arrange a safe exit either way. See our Vietnam overstay fines guide for the full Decree 282/2025 schedule.
Are there ATMs or money changers at Moc Bai if I run out of cash?
Yes. Official exchange counters at the Moc Bai gate change USD and VND, and ATMs are available on the Cambodian side around Bavet, including at the casino complexes. Still, don't rely on them: bring enough USD and VND to cover both border fees before you leave Saigon, because ATM limits, withdrawal fees, and exchange rates at the border are rarely in your favor.
