As a US citizen living in Vietnam, you likely enjoy the country's vibrant culture, affordable living, and delicious food. However, unless you have a long-term visa, at some point you have to leave Vietnam and start a fresh stay from outside the country. For those based in Ho Chi Minh City (HCMC), the Moc Bai border crossing into Cambodia is the most popular option. This guide covers everything you need to know: from paperwork and costs to timings and tips: so you can breeze through the process.
Why US Citizens Need a Visa Run
US citizens are not on Vietnam's visa exemption list, so every trip starts with a visa. The e-visa is the standard route: USD 25 for single entry, USD 50 for multiple entry, valid for up to 90 days either way, applied for online about a week ahead. Choose multiple entry if you might leave Vietnam and come back inside those 90 days and you skip the run entirely. A visa run still earns its place when your stay is nearly up and you have no new e-visa in hand, or when a trip to Cambodia was on the cards anyway.
Important: the e-visa is open to every nationality, US passports included, and the 90-day multiple-entry version covers most people who plan to come and go. If your application is refused, or your stay is nearly up, a visa run is the fallback that works the same week.
Moc Bai Border: The Best Option for HCMC Residents
Located about 70 km northwest of HCMC, Moc Bai is the closest land border crossing to Cambodia. It’s open daily from 6:00 AM to 10:00 PM Vietnamese time, with no lunch break. The crossing is straightforward, with both Vietnamese and Cambodian immigration offices on site. Most visa run services use Moc Bai because of its proximity and efficiency.
Step-by-Step Visa Run Process for US Citizens
Here’s what a typical visa run to Moc Bai looks like:
- Step 1: Pre-arrange your visa. You need a new visa before leaving. Options: e-visa (apply online 3-5 days ahead) or visa on arrival (letter from a travel agency). US citizens can use e-visa for a stay of up to 90 days: USD 25 for single entry, USD 50 for multiple entry.
- Step 2: Book a visa run service. Saigonvisarun.com offers door-to-door transport, assistance with forms, and guidance. Departure from HCMC District 1 at 5:00 AM, return by 2:00 PM.
- Step 3: Travel to Moc Bai. The drive takes 1.5-2 hours. You’ll cross into Cambodia, stamp out of Vietnam, then re-enter with your new visa.
- Step 4: Complete immigration. At the Cambodian side, you’ll get an exit stamp. Then re-enter Vietnam with your new visa. Total time at border: 30-60 minutes.
- Step 5: Return to HCMC. Your service drives you back, arriving by early afternoon.
Costs Breakdown
Visa runs are affordable compared to flights. Here’s what you’ll pay:
- Transport (shared minivan): 500,000 VND ($20) per person. Private car: 1,200,000 VND ($50).
- Visa fee: E-visa $25 (30-day) or $50 (90-day). Visa on arrival letter: $10-20 + stamping fee $25 (single entry) or $50 (multiple).

What Documents Do US Citizens Need?
To ensure a smooth visa run, bring these items:
- Valid US passport with at least 6 months validity and 2 blank pages.
- Your new Vietnam visa (e-visa printout or visa on arrival letter).
- 2 passport-sized photos (4x6 cm) for visa on arrival.
- Cash (USD or VND) for stamping fees. No cards accepted at border.
- Your old visa stamp (if any). Sometimes checked.
- Cambodia transit pass (provided by your service).
Pro Tip: Always carry photocopies of your passport and visa. Border officials occasionally ask for them, and having copies saves time.
Common Pitfalls and How to Avoid Them
Even experienced travelers hit snags. Here are top issues US citizens face:
- Expired visa before run. If your visa expires before you return, you’ll be fined (500,000 VND per day). Always do the run before expiry date.
- Wrong e-visa type. US citizens must select '30-day single entry' or '90-day multiple entry' correctly. Choosing tourist vs. business matters.
- Missing exit stamp. When leaving Vietnam, ensure you get an exit stamp from Vietnamese immigration. Without it, re-entry may be denied.
- Cambodia visa confusion. For same-day runs, you don’t need a Cambodia visa. But if you stay overnight, you must purchase one ($30).
- Language barriers. Border staff speak limited English. Use a service like saigonvisarun.com for translation help.
Timings: Best Days and Hours
Moc Bai is busiest on weekends and holidays. For fastest service:
- Best days: Tuesday, Wednesday, Thursday. Avoid Monday and Friday when crowds peak.
- Best time: arrive at the border by 7:00 AM, an hour after the gate opens. Early morning means shorter lines.
- Avoid Tet (Lunar New Year) and public holidays. Border can be chaotic.
- Allow 2 hours for the entire border process on slow days, up to 4 hours on busy days.
Red Alert: Do not attempt a visa run on the last day of your visa. If there’s a delay (e.g., car breakdown, long lines), you’ll incur overstay fines. Always go 2-3 days before expiration.
