Cambodia Visa Overstay Fines for US Travelers: Costs and How to Avoid Them
A Cambodia visa overstay costs US travelers $10 per day, charged in cash at the airport when you leave. Here is exactly how the per-day fine works, how it escalates past the cheap zone, and how to make sure you never pay a cent of it in 2026.
How much is the Cambodia visa overstay fine per day for US citizens?
Cambodia charges US citizens a visa overstay fine of $10 USD per day, collected in cash at the airport Immigration counter on the day you leave. A 3-day overstay costs $30, a week costs $70, and the meter keeps running for every day past your 30-day stay. This per-day fee applies to short overstays. Once an overstay runs long — roughly past 30 days — Cambodian Immigration can stop treating it as a fee and start treating it as an immigration offense, which opens the door to detention, deportation at your own cost, and a ban on returning. Your 30-day stay is counted from the day you enter, single entry, and the tourist auto-extension ended in November 2025, so the only legal way to stay longer is a Business eVisa you can extend in-country. The reliable way to pay nothing is to count your days from the entry stamp and leave on time.
主なポイント
- Cambodia charges a visa overstay fine of $10 USD per day, paid in cash at the airport Immigration counter when you depart — not at the start of your trip.
- A short overstay is treated as a fee; a long overstay is treated as an immigration offense. Past roughly 30 days the math stops being a number on a receipt and starts risking detention, deportation, and a re-entry ban.
- Your 30-day clock starts the day you enter Cambodia, not the day your eVisa was issued. The eVisa is valid for 3 months from issue, but the stay itself is a hard 30 days, single entry.
- The tourist auto-extension ended in November 2025, so a Tourist eVisa is now a firm 30-day ceiling. The only legal way to stay longer is a Business eVisa, which can be extended from inside Cambodia.
- The cheapest overstay fine is the one you never pay. Counting your days from the entry stamp, setting a phone reminder for day 28, and choosing the right visa up front costs nothing and removes the risk entirely.
The per-day fine, in one number
A Cambodia visa overstay costs a US traveler $10 USD per day. You do not pay it when you arrive and you do not pay it online — it is collected in cash at the Immigration counter at the airport on the day you fly out. Stay three days past your 30-day limit and the officer adds $30 to your departure. Stay a week over and it is $70. The meter is simple, it is per day, and for a short overstay that is genuinely the whole story.
Where it stops being simple is duration. A day or two over your stay is an administrative fee that you settle at the counter and forget. A month over is no longer a fee — it is an immigration offense, and the consequences shift from a line on a receipt to detention, deportation paid out of your own pocket, and a flag against your passport that can block you from coming back. The difference between those two outcomes is entirely about how many days you let slide, which is exactly why this guide leads with the number and then shows you where the number stops mattering.
Below you will find the exact per-day cost, how the fine escalates from a fee into a serious problem, where your 30-day clock actually starts, and the cheapest move of all — never triggering the fine in the first place. The short version: count your days from the entry stamp, not the eVisa issue date. If you are still planning the trip, our guide to how long US citizens can stay in Cambodia sets the baseline this whole article is built on, and you can always apply online when you are ready.
How the $10-per-day overstay fine actually works
The overstay fine is charged at $10 USD for each day you remain in Cambodia past the last valid day of your stay. It is calculated by counting calendar days, not business days, so weekends and Cambodian public holidays still count against you. The officer at the departure counter checks your entry stamp against the date on your boarding pass, does the subtraction, and tells you what you owe before they let you through.
You pay in cash, at the airport, on the way out
There is no online portal for the overstay fine and no card terminal at the Immigration desk. You pay in US dollars in cash, which is the working currency at Cambodian airports, and you pay it at the moment you are trying to leave. That timing matters: an overstay you have not planned for can mean scrambling for an ATM in the departures hall while your flight boards. Travelers who realize mid-trip that they are going to run over should set the cash aside early rather than discover the bill at the worst possible moment.
A short overstay does not get you arrested, banned, or marked as a problem traveler. For a handful of days, Cambodian Immigration treats it as a routine fee — you pay, the officer notes it, and you board. Thousands of travelers each year miscount by a day or two, settle the fee, and never think about it again. The system is built to let small overstays resolve themselves at the counter without drama.
よくある質問
How much is the Cambodia visa overstay fine per day for US citizens?
Cambodia charges $10 USD per day for a visa overstay, collected in cash at the airport Immigration counter when you depart. A 3-day overstay costs $30, a week costs $70, and the charge keeps adding $10 for each calendar day past your 30-day stay. For a short overstay this is a routine fee you settle at the counter; for a long overstay it can become an immigration offense with far more serious consequences.
When and how do I pay a Cambodia overstay fine?
You pay in US dollars in cash at the Immigration counter at the airport, on the day you leave Cambodia. There is no online portal and no card terminal for the overstay fine. The officer checks your entry stamp against your departure date, calculates the days over, and collects the fee before clearing you to board, so have the cash ready if you know you have run over.
What happens if I overstay my Cambodia visa by a long time?
A long overstay — in practice past roughly 30 days — can stop being a simple fee and become an immigration offense. That can mean detention while your case is processed, deportation at your own expense, and a ban on returning to Cambodia for a period of years. There is no published bright line, and the longer you stay the more an officer can escalate, so a long overstay is a genuine travel emergency, not a budget line.
Does my 30-day stay start when my eVisa is issued or when I arrive?
When you arrive. The eVisa is valid for 3 months from issue, which is your window to enter Cambodia, but the 30-day stay starts the day you actually enter and get your passport stamped. Overstay fines count against that 30-day stay, not the 3-month validity. Count 30 days from your entry stamp to find your last legal day — counting from the eVisa email is the most common way Americans overstay by accident.
Can I extend my Cambodia visa to avoid an overstay fine?
Only on a Business eVisa. The tourist auto-extension ended in November 2025, so a Tourist eVisa is a firm 30-day ceiling that cannot be extended — when it ends, you leave. A Business eVisa can be extended from inside Cambodia for 1, 3, 6, or 12 months through an immigration agent. If your trip might run long, choosing the Business eVisa up front is far cheaper and calmer than risking an overstay.
Can I cross a land border to reset my Cambodia stay?
No. All seven Thailand-Cambodia land borders have been closed since June 2025, so the old overland-hop trick is not available. Both Cambodia eVisa types are single entry anyway, which means leaving and re-entering ends the visa rather than resetting your stay — you would need a fresh eVisa to come back. There is no border run that buys you extra days.
