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, you'll need to renew your stay every 30 days with a visa run. 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 typically enter Vietnam on a 30-day single-entry visa (e-visa or visa on arrival). After 30 days, you must leave the country to get a new visa. A visa run involves exiting Vietnam, re-entering with a fresh visa, and resetting your stay. While Vietnam introduced 45-day visa exemptions for some nationalities in 2023, US citizens remain on the 30-day single-entry system unless they qualify for a 90-day multiple-entry visa (available online). For most expats and travelers, a visa run every month is the standard solution.
Important: As of 2024, US citizens can apply for a 90-day multiple-entry e-visa online, which eliminates the need for monthly runs. However, if you already have a 30-day single-entry visa, or if your e-visa application is denied, a visa run remains a reliable fallback.
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 7:00 AM to 10:00 PM (Vietnamese time; Cambodia is 1 hour behind). 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 30-day single-entry ($25) or 90-day multiple-entry ($50).
- 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 border by 7:00 AM (open at 7:00 AM Vietnam time). 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.
