How Long Can US Citizens Stay in Cambodia on an eVisa?
A Cambodia eVisa gives US citizens a 30-day stay on a single entry, and the visa itself stays valid for three months from issue. Here is exactly how the two clocks work, what counts as a day, and why the rules changed for Americans in 2026.
How long can US citizens stay in Cambodia on an eVisa?
A Cambodia eVisa gives US citizens a 30-day stay, counted from the day you are stamped in at the airport. It is a single-entry visa, so it covers one trip only — leave Cambodia and the visa is used up, even if days remain. Separately, the visa is valid for 3 months from its issue date, which is simply the window you have to arrive and start the clock. The old tourist auto-extension ended in November 2025, so 30 days is now the firm limit on the Tourist eVisa. If you need to stay longer, the Business eVisa is the version that can be extended inside Cambodia. The Tourist eVisa cannot be.
نکات کلیدی
- A Cambodia eVisa lets US citizens stay 30 days from the date you are stamped in — counted as calendar days, not nights, with arrival day as day one.
- The eVisa is valid for 3 months from its issue date. That is your window to arrive; the 30-day stay clock only starts once you actually enter Cambodia.
- The eVisa is single entry. Leave the country and the visa is spent — you cannot use it to come back, even if days remain on the 30-day stay.
- The tourist auto-extension that used to add time at the airport ended in November 2025, so 30 days is now a hard ceiling on the tourist eVisa.
- Need longer than 30 days? The Business eVisa ($90 USD, 3 business days) is the route that can be extended in-country, where the Tourist eVisa cannot.

سوالات متداول
How long can US citizens stay in Cambodia on an eVisa?
Thirty days, counted from the day you are stamped in at the airport. Cambodia counts calendar days, not nights, and your arrival day is day one. The 30-day stay is the same at all three international airports, and since the tourist auto-extension ended in November 2025, it is now a hard ceiling on the Tourist eVisa rather than a number you can stretch on arrival.
Is the 30-day stay the same as the 3-month validity?
No, and this is the most common mix-up. The 3-month validity is the window you have to arrive — the shelf life of the visa from its issue date. The 30-day stay is how long you can remain once you enter, and it only starts when an officer stamps you in. They are separate clocks that never add together. You always get 30 days from entry, no matter how early in the validity window you arrive.
When does my 30-day stay actually start?
When an immigration officer stamps your passport on arrival — not when your visa is approved, not when you pay, and not when you book a flight. You could hold an approved eVisa for weeks before traveling and still get your full 30 days from the day you walk through the desk. That is why applying early carries no penalty: the stay clock waits until you land.
Can I leave Cambodia and come back on the same eVisa?
No. The eVisa is single entry, so it covers one admission only. The moment you exit Cambodia — to Vietnam, Laos, or a regional flight — the visa is spent, even if days remain on your 30-day stay. To return, you need a new eVisa. If your route loops out and back, apply for a second eVisa before you travel, or choose a multiple-entry-capable visa from the start.
Can I extend my stay past 30 days?
Not on a Tourist eVisa. The tourist auto-extension ended in November 2025, so 30 days is the firm limit and there is no in-country path to add more on a tourist visa. The Business eVisa is the version that can be extended inside Cambodia. If there is any real chance you will want more than a month, choose the Business eVisa at the start, because you cannot convert a Tourist eVisa into an extendable one after you arrive.
What happens if I overstay my 30 days?
Cambodia charges a per-day fine for every day past your 30-day stay, payable at departure, and an overstay flag can complicate a future entry. With the auto-extension gone, there is no soft buffer anymore — day 31 is an overstay. If your trip is genuinely longer than a month, the cost of the right visa up front is trivial next to an overstay penalty at the airport.
