eVisa vs Visa on Arrival for Cambodia: Why US Travelers Should Apply Online First

eVisa vs visa on arrival: the honest side-by-side

Here is the comparison for US citizens choosing between the two routes in 2026. The rows that decide it for most travelers are the bottom three — where it works, boarding risk, and what happens if something goes wrong.

Read down that table and the pattern is hard to miss. The eVisa front-loads all the effort to a calm moment at your kitchen table, where a flagged photo or a typo is a five-minute fix with free resubmission. The visa on arrival pushes every one of those same steps to the worst possible moment — standing in a queue after a 20-hour journey, with a flight crew gone home and a hotel transfer waiting.

The price difference is not the deciding factor people expect. The on-arrival counter is not a discount route — you still pay a real fee, in cash, on the day. What the eVisa buys you for a comparable price is certainty: you know you are getting in before you board, and you are not depending on the counter being staffed, the card terminal working, or your cash being the right currency. If the money is what is driving the question, the breakdown of why the eVisa is cheaper than visa on arrival lays out the real numbers side by side.

Why applying online first wins for US travelers

The case for the eVisa is not about saving a few dollars. It is about removing the variables that turn a long-haul arrival into a problem. Here is what applying online before you fly actually protects you from.

• Boarding refusal in the United States. Airlines check for a valid visa or eVisa at the US gate before they let you on. Turn up at LAX, SFO, or JFK with nothing and the desk agent can lawfully refuse to board you, because the carrier eats the fine if Cambodia denies you entry. An approved eVisa PDF settles that question on the spot.
• The post-flight queue. The on-arrival counter sits between you and Immigration. You complete a paper form, hand over a photo, and wait — after a transpacific flight, with a sleeping family or a tight onward connection. Travelers who applied online walk straight past it to the Immigration desk.
• Cash and currency surprises. The counter wants payment in cash, and travelers regularly arrive with the wrong currency, the wrong denominations, or an ATM that is down. The eVisa is paid online from home with a normal US card.
• The missing photo. The on-arrival form needs a physical passport photo. Forget it or pack it in checked luggage and you are improvising at the counter. The eVisa photo is uploaded digitally weeks earlier.
• No fix-it window. If your on-arrival paperwork has a problem, you are solving it jet-lagged at the desk. An eVisa flagged for a correction comes back to your inbox with free resubmission while you are still at home — the clock keeps running and you reach the airport sorted.
• The land-border trap. The on-arrival counter is airport-only. If your itinerary ever touches a land crossing from Thailand, there is no counter to use and the borders are closed anyway. The eVisa is the only route that survives a change of plan.

None of this is hypothetical. The travelers who run into trouble at KTI are almost always the ones who assumed the counter would be quick and frictionless. The ones who breeze through are the ones holding a printed PDF. If you want to see the exact sequence — form, upload, payment, approval — the step-by-step application walkthrough takes about ten minutes from start to finish.

When the on-arrival counter is even worth considering

Honesty matters here, so here is the narrow set of situations where a US traveler might genuinely reach for the on-arrival counter — and why even those cases usually still point back to applying online.

The classic argument is the true last-minute trip. If you are flying in less than 3 business days and the eVisa processing window does not fit, the counter looks like the only option. But this is rarer than it sounds for Americans, because the bottleneck is usually the US end of the journey — booking the flight, getting to the airport — not the visa. If you have a flight booked, you almost always have time to apply online before you fly, and applying online means you also clear the boarding gate cleanly. The counter only helps if you are genuinely inside the processing window with a confirmed seat, which is an unusual corner.

The other argument is "I have always done it that way." Plenty of Americans who traveled to Cambodia before the pandemic remember the on-arrival sticker as routine. It still works at the three open airports, so the muscle memory is not wrong — it is just no longer the smart default. The new KTI arrival flow, the mandatory e-Arrival Card, and the closed land borders all reward travelers who arrive with the visa already in hand.

There is no land-border version of this conversation at all. With all seven Thailand-Cambodia crossings closed since June 2025, the only realistic overland entries are from Vietnam at Bavet or from Laos at Tropaeng Kreal — and those crossings do not run a tourist on-arrival counter for Americans either. If your trip was ever going to involve a Bangkok-to-Siem Reap land hop, it is worth checking which airport or port of entry you can actually use before you book, because an eVisa flown in is the answer.

The step both routes share: the e-Arrival Card

Here is the part travelers comparing the two routes almost always miss: the e-Arrival Card is mandatory for every air arrival regardless of which visa route you take. It is a separate online form, not part of either the eVisa or the on-arrival process, and it does not go away if you choose the counter.

The e-Arrival Card is 14 fields across three short sections, submitted within 7 days before your arrival. It captures the arrival data Immigration used to collect on paper — flight number, accommodation address, customs declaration — and produces a QR code you present at the airport. This is genuinely the most common 2026 trip-stopper at the kiosk, and it catches on-arrival travelers especially hard: they assume the counter handles everything, then discover the e-Arrival is a step they still owe.

This is the quiet reason the on-arrival counter saves you less than it seems. Even if you skip the eVisa and queue at the counter, you still have to file the e-Arrival Card in the week before you fly. So you are doing online paperwork from home either way — the only question is whether you also settle the visa at the same calm moment, or save it for a queue. Settling both before you fly is the obvious move.

If you are not sure whether you need the e-Arrival Card on top of an eVisa, the answer is yes, every air arrival files it — the do you need the e-Arrival Card with an eVisa explainer walks through why both are required and how they fit together.

The bottom line for US travelers

For almost every American flying to Cambodia in 2026, the decision is settled before it starts: apply for the eVisa online first. The Tourist eVisa is $80 USD all-in and the Business eVisa is $90 USD all-in, both approved in 3 business days, both delivered as a printable PDF by email, both with free resubmission if Immigration flags a correction and US-timezone support if you get stuck. You clear the boarding gate cleanly, you skip the arrivals counter, and you remove the one variable most likely to derail a long-haul arrival.

The on-arrival counter is not a trap, and it is not a scam — it is simply a slower, riskier fallback that made more sense in a world with open land borders and no mandatory e-Arrival Card. That world ended in 2025. Today the counter costs about the same, exists at fewer places, and pushes all the work to your most tired moment. There is no upside left that the eVisa does not beat.
