What happens at the Vietnam border during a Visa Run

Published 3 September 2026 · Reviewed 2026-09-08 · 5 min read

Most anxiety about a Visa Run is about the border itself. In practice it is five counters and a short walk. This is what each one looks like at the gates we use from Hanoi.

Before you get out of the car

Have in your hand: passport, printed e-visa (two copies), Laos or Chinese visa if applicable, a pen. Put your USD in a separate envelope. Phone charged. Your coordinator will tell you which building to enter; at Huu Nghi and Mong Cai there are separate halls for cars and pedestrians.

Counter 1: Vietnam exit

Hand over your passport. The officer scans it, checks you are within your permitted stay, may ask "Where are you going?" ("Laos" / "China, one day") and stamps an exit stamp. If you have overstayed, this is where it is discovered and fined. Time: 2–10 minutes, longer in queues.

The neutral zone

At Huu Nghi there is an electric shuttle between the two sides (a few thousand dong); at Mong Cai you walk across the bridge; at Cau Treo, Na Meo and Lao Bao it is a short walk or a ride in the same vehicle. You are now between countries. Do not take photos of the checkpoints.

Counter 2 and 3: the other country's entry and exit

China (Huu Nghi / Mong Cai): fingerprints and photo on entry, a form, a quick check of your visa or visa-free eligibility, and questions about the purpose of the trip. Answer plainly: "Day trip, going back to Vietnam this afternoon." You may walk into Pingxiang or Dongxing. Exit is the same counter hall, reverse direction.

Laos (Cau Treo / Nam Can / Tay Trang / Na Meo / Lao Bao): a small hall. With a pre-arranged visa: passport check, digital immigration form (done in advance), entry stamp. At Lao Bao with visa on arrival: fill the form, hand over a photo and the USD fee, wait for the sticker, then the entry stamp. Overtime or weekend fees, where they exist, are small and official; your coordinator tells you what is legitimate. You may stay a few minutes or a few days. Exit stamp when you come back.

Counter 4: Vietnam entry

This is the one that matters. Present your passport and the printed e-visa. The officer checks that the visa's entry port matches this gate, that today's date is within its validity, and that your name and passport number match. Then the entry stamp and a handwritten or printed permitted-stay date. Check that date before you walk away. If your passport is visa-exempt, the officer simply stamps you in for the exemption period (45 days for the unilateral-exemption countries, 30 for most ASEAN).

Counter 5: customs

Usually a walk-through with a baggage scanner. Nothing to declare on a day trip.

What officers actually ask

• Purpose of the trip and how long you will stay in the other country.
• Where you live in Vietnam and what you do (be consistent with your visa type).
• Occasionally, proof of accommodation or onward travel. Keep a hotel booking or your Vietnamese address handy.

Officers at international gates handle foreigners every day. Polite, brief, consistent answers are all that is needed. Your coordinator can help translate if a question is unclear.

What can go wrong, and what we do

• Wrong port on the e-visa: the most common real problem. We check this before departure so it does not happen.
• Visa-free eligibility not recognised: lists change. We check yours on the day of booking.
• Long queues: holidays and weekends. We schedule early departures.
• Refusal: rare with correct documents. If it happens your coordinator helps you understand the reason and your options; we do not leave you at the gate.

Procedures vary by gate and change over time. This describes typical experience at the gates we use, as of the review date, and is not individual legal advice.
