Flying to Cambodia more than once this year? Every arrival is its own visa and its own e-Arrival Card, so the real skill is timing — knowing exactly when to file each one against your calendar. Here is the trip-by-trip timeline Americans use to schedule two, three, or a dozen Cambodia visits in a single year without a single last-minute scramble.
Plan around arrivals, not trips, because every Cambodia arrival needs its own single-entry eVisa and its own e-Arrival Card. For each trip, file the eVisa roughly two weeks before that arrival — it is approved in 3 business days and stays valid for 3 months from issue, which is your deadline to enter, not a window to come and go. Then file that trip's e-Arrival Card inside the 7-day window before the flight. Repeat the same two-step pattern for each arrival across the year. The price is identical every time — $80 USD Tourist or $90 USD Business — there is no cap on how often you can re-apply, and no cooling-off period between visits. The only real planning skill is timing each pair of filings against your calendar so nothing lands at the last minute.
You are not flying to Cambodia once this year — you are flying two, three, maybe a dozen times. A consultant on a quarterly Phnom Penh rotation. A retiree who escapes back for the cool season and again for a festival. A regional traveler looping through Vietnam and Laos with Cambodia as the hub. The question is no longer "do I need a visa" — you know you do, and the full rules sit in our complete guide to the Cambodia visa for US citizens. The question is when to file each one so you are never scrambling at a gate.
Here is the mental shift that makes a year of Cambodia trips easy: stop counting trips and start counting arrivals. Cambodia issues single-entry eVisas, so every separate arrival into the country is its own visa and its own e-Arrival Card. A clean there-and-back trip is one arrival. A trip with a side hop to Vietnam in the middle is two arrivals. Once you have your year mapped by arrival dates, the visa timeline becomes a simple repeating rhythm you run once per arrival.
This guide lays out that rhythm trip by trip: how far ahead to file each eVisa, how the 3-month validity interacts with a packed calendar, exactly when each e-Arrival Card is due, and how to sequence a year that includes side trips and long stays. For the underlying rule that drives all of it — that you need a brand-new eVisa for every single visit — start with our explainer on needing a new Cambodia eVisa every trip, and when you are ready to lodge your next one you can apply in a few minutes.
Mark every date you will physically enter Cambodia; each arrival triggers one eVisa and one e-Arrival Card.
A trip with a mid-journey hop out and back is two Cambodia arrivals, so two eVisas and two e-Arrival Cards.
It is approved in 3 business days and valid 3 months from issue, so two weeks ahead leaves comfortable slack.
The 14-field e-Arrival Card must be submitted inside the 7-day window before that flight, separate from the visa.
Run the same two filings for every landing — Tourist eVisa $80 or Business eVisa $90, with no frequency cap.
Before you can schedule a year, you need the unit you are scheduling. Every Cambodia arrival is built from exactly two filings, and they are separate systems with separate timing. Get this pair clear and the whole calendar falls into place, because you are simply stamping the same pair onto each arrival date.
The first filing is the eVisa — your permission to enter. It is single-entry, approved in 3 business days, and valid for 3 months from the date it is issued. That 3-month number is the part frequent travelers misread. It is not a license to come and go for three months; it is the deadline by which you must make your one arrival. You enter once on that visa, and the moment you leave Cambodia it is spent, no matter how many of your 30 stay-days were left.
The second filing is the e-Arrival Card — the mandatory digital arrival declaration every air traveler completes before landing. It is 14 fields covering your flight, your Cambodia address, and a short customs declaration, and it must be filed inside the 7-day window before your flight. Like the visa, it is strictly per-arrival: a fresh Card for every single landing, no carry-over from a previous trip.
Sit down with a calendar and mark every date you will physically walk through Cambodian Immigration this year. Not departure dates, not trip names — arrival dates. That list is your filing schedule, because each arrival date triggers one eVisa and one e-Arrival Card. This sounds obvious, but it is exactly where returning Americans miscount, and the miscount always comes from side trips inside a single journey.
A there-and-back trip is one arrival. Fly into Phnom Penh in March, spend two weeks, fly home — that is a single arrival, so one eVisa and one e-Arrival Card. Easy. But say in July you fly into Siem Reap, pop over to Vietnam for a few days mid-trip, then come back into Cambodia to fly home from Phnom Penh. That single journey contains two Cambodia arrivals, which means two eVisas and two e-Arrival Cards — the first visa is consumed the instant you leave for Vietnam.
The lesson is that "trips" and "arrivals" are not the same number, and your wallet follows arrivals. A loop with a mid-trip border hop quietly doubles a leg. If your year includes any side-country travel, our guide to needing a new e-Arrival Card each trip walks through why even the arrival declaration cannot be shared across legs, so you can count your filings correctly before you book anything.
Now the schedule itself. For each arrival on your year map, you run the same two-step countdown. The numbers never change between trips, which is what makes a busy year manageable — you are repeating one reliable pattern, not learning a new one each time.
The eVisa is approved in 3 business days, so technically you could cut it close. Do not. File roughly two weeks before each arrival. That gives the 3-business-day approval room to clear over a weekend or a US holiday, and it leaves slack for a free resubmission if Immigration flags a photo or a scan. Because the visa is valid for 3 months from issue, filing two weeks ahead is comfortably inside the window — you cannot file "too early" in any way that wastes the visa, as long as your arrival falls within those 3 months.
One timing trap on a packed calendar: do not file an eVisa more than 3 months before the arrival it is meant to cover, because it would expire before you land and you would have to buy another. For trips spaced far apart across the year, file each one in its own two-week-out window rather than trying to batch them all at once in January.
The e-Arrival Card has a hard 7-day rule: it must be submitted within the 7 days before your arrival, not earlier. So for each trip, the Card is a later, separate task than the visa — visa two weeks out, Card in the final week. Put both on your calendar as two distinct reminders per arrival. The most common returning-traveler slip is filing the visa early, feeling done, and then forgetting the Card is still owed in the final week.
For multi-trip travelers the cleanest system is a recurring reminder per arrival date: one alert at "minus 14 days" for the visa, one at "minus 6 days" for the e-Arrival Card. Our deep-dive on the e-Arrival 7-day window for Americans covers the exact open and close of that window, including how it behaves on long-haul flights from the US that cross the international date line.
Mapping a year of arrivals makes one thing obvious fast: if your real goal is to be in Cambodia for a long continuous stretch rather than genuinely separate trips, stacking visa after visa is the wrong tool. A "visa run" — a quick hop out and back just to reset the clock — burns a second eVisa and a second e-Arrival Card for nothing, and it adds a flight that exists only to satisfy paperwork.
There are two clean shapes for a year-heavy Cambodia plan, and choosing between them is the most valuable decision the Returning-Travelers desk helps with. If you are making genuinely separate trips — fly in, fly all the way home, come back months later — repeat single-entry Tourist eVisas are exactly right, one per arrival. If you want one long stay, the Business eVisa is the answer, because it is the only Cambodia visa you can extend from inside the country in 1, 3, 6, or 12-month blocks through an immigration agent.
Note the route that no longer exists: the automatic tourist extension that some travelers remember ended in November 2025, so you cannot stretch a Tourist eVisa in-country anymore. For a long stay it is the Business eVisa and a proper extension, not a Tourist eVisa plus hope. One entry, then extend — and your year stops being a string of visa filings altogether.
If your year sits somewhere in the middle — several real trips, but a couple of them long — it is worth pricing both paths before you commit. Our breakdown of single vs multiple-entry Cambodia visas for Americans lays out when repeat single-entry filings win and when a longer-stay structure saves you money and airport time across the calendar.
A few situations come up over and over for Americans who treat Cambodia as a regular destination rather than a one-off. None of them is complicated once you know the rule, but each one quietly reshapes the timeline if you miss it.
Americans worry that filing eVisa after eVisa across a year will trip some kind of frequency flag. It will not. There is no cap on the number of single-entry eVisas you can hold across separate trips, no mandatory cooling-off period between visits, and no penalty for being a frequent flyer. A consultant who flies in monthly files twelve times a year, every time at the same $80 Tourist or $90 Business price and the same 3-business-day approval. Each application stands completely on its own.
If your passport renews partway through your travel year, the new passport number means every eVisa after that point is tied to the new document — re-scan the new bio page and apply on it. Your eVisa is bound to the passport number you applied with, so never enter on a different passport than the one your current eVisa names. For a year of trips, line your renewal up with a gap between arrivals so no single trip straddles the change.
If your year-round plan used to include a road loop through Thailand, redraw it: all 7 Thailand-Cambodia land borders have been closed since June 2025, so a Cambodia-Thailand-Cambodia leg by road is not currently possible. You fly the leg instead, and each flight back into Cambodia is still a fresh single entry that needs its own eVisa and its own e-Arrival Card on the timeline. For the practical re-entry mechanics on a regional year, our guide to Cambodia visa runs for returning Americans in 2026 covers what works now and what does not.
The whole system fits on a single line: count arrivals, and run the same two-step countdown for each one. File the eVisa about two weeks out, file that trip's e-Arrival Card inside the final 7 days, and repeat the pair for every separate Cambodia landing on your calendar. A year with four arrivals is just that rhythm run four times — no special multi-trip product, no frequency limit, no penalty for coming back often.
And the cost is predictable trip to trip. Each arrival is a Tourist eVisa $80 USD or a Business eVisa $90 USD, approved in 3 business days, delivered as a printable PDF by email, with free resubmission if Immigration flags a correction and US-timezone support behind it. Each arrival also needs its own e-Arrival Card: $5 USD verified through us, 14 fields, filed within 7 days before that flight. Map it once, and a year of Cambodia trips runs itself.
