Do US Citizens Need a Visa for Cambodia? What Americans Must Know in 2026

Which Cambodia visa do you need — Tourist or Business?

For the overwhelming majority of Americans, the answer is the Tourist eVisa. It covers vacations, visiting friends and family, Angkor Wat, the beaches at Sihanoukville, river trips, and any leisure travel. It costs $80 USD all-in, is approved in 3 business days, and gives you a single entry with a 30-day stay. If you are reading this to plan a normal trip to Cambodia, this is your visa.

The Business eVisa exists for a narrower set of travelers: attending meetings, scoping a supplier, conference travel, or any work-adjacent purpose. It is $90 USD all-in, also approved in 3 business days, and is the only Cambodia visa class that can be extended once you are inside the country. If your trip is purely a holiday, you do not need it and should not pay the extra for it. If there is any work component, the Business eVisa is the honest choice and it keeps your options open for a longer or repeat stay later.

Both visas are single-entry. If you plan to leave Cambodia and come back during the same trip — say, a side trip to Vietnam and back — a single-entry visa means you would need a fresh visa for the return. Plan your routing with that in mind, because the land-border situation in 2026 (covered below) makes some loop itineraries harder than they used to be.

If you are genuinely unsure which class fits your trip, the side-by-side breakdown in our Cambodia Tourist visa vs Business visa guide for Americans lays out the decision by trip purpose, and the Type-T vs Type-E explainer decodes the visa-class labels you will see on the application form. For most readers, though, it is the Tourist eVisa — and you can start that application now.

How long US citizens can stay, and the validity window

The Cambodia eVisa gives you a 30-day stay from the day you enter the country. That is a calendar count, not business days, and it includes your arrival day and your departure day. For a typical American trip — a week or two split between Phnom Penh, Siem Reap, and the coast — 30 days is comfortably more than you need.

The number that trips people up is the validity window, which is different from the stay. Your eVisa is valid for 3 months from the date it is issued, not from the date you enter. So if you apply in January and your visa is issued the same week, you must enter Cambodia by roughly mid-April. Enter on the last valid day and you still get your full 30-day stay from that entry. The practical rule: do not apply so far ahead that the visa expires before your trip. A few weeks out is the sweet spot.

One change every American should know about: the tourist visa auto-extension ended in November 2025. In the past, tourists could lean on an automatic short extension; that path is gone. If you need longer than 30 days now, you either apply for a fresh visa or, for work travel, use the extendable Business eVisa. The full mechanics — including the timing math and what counts as an overstay — are covered in our guide to how long US citizens can stay in Cambodia.

What your US passport needs to look like

Your US passport must have at least 6 months of validity remaining from your date of entry into Cambodia, and at least one full blank page for the entry stamp. This is the single most common reason an American trip gets derailed before it starts — not a visa problem at all, but a passport that expires inside the 6-month window. The airline checks this at your departure gate in the United States and will deny boarding if your passport is too close to expiry, long before you ever reach a Cambodian immigration officer.

Run the math now, not at the airport. If your passport expires in September and you are flying out in July, you are inside the 6-month window and you will be turned away. US passport renewals through the State Department take time — routine service can run several weeks, and even expedited service is not instant — so if you are close to the line, renew before you book anything else. A blank page also matters: if your passport is full of stamps from frequent travel, count your clean pages before you fly.

The name and details on your eVisa application must match your passport exactly — same spelling, same characters as the machine-readable zone at the bottom of your photo page. A mismatch here is a leading cause of avoidable hold-ups. For the full breakdown of the validity rule, blank-page count, and what to do with a damaged or near-expiry passport, see the Cambodia passport requirements for Americans and the dedicated 6-month-rule guide.

Where your eVisa works: airports, borders, and the 2026 changes

Two big things changed in 2026 that directly affect how Americans should plan their entry into Cambodia, and both push you toward arriving by air. Get this right and your eVisa works smoothly; get it wrong and you can find yourself at a closed crossing with a visa you cannot use.

First, the airport. Phnom Penh now flies into KTI — Techo International Airport — which replaced the old PNH airport on 9 September 2025. If you are flying into the capital, your inbound ticket and your e-Arrival card should reflect the new airport. Siem Reap (for Angkor Wat) and Sihanoukville (for the coast) also accept eVisa arrivals, so most American itineraries are well served by air.

Second, the land borders. All 7 Thailand–Cambodia land borders have been closed since June 2025. That means the classic backpacker move of busing from Bangkok into Cambodia overland is not an option in 2026, and any itinerary that assumed an overland Thailand–Cambodia leg needs rerouting through a flight. If your plan was Thailand first and Cambodia second by road, you now fly that leg instead. Your eVisa is valid at the international airports; it cannot be used at a closed land crossing.

Before you lock in flights, confirm your specific port of entry accepts the eVisa — the full, current list of eligible airports and crossings is in our Cambodia eVisa eligible entry points guide for US citizens, which is updated as the border situation evolves. The short version for 2026: fly in, and fly into KTI, Siem Reap, or Sihanoukville.

The second form Americans forget: the e-Arrival card

Here is the step that catches even well-prepared travelers: the eVisa is not the only thing you file. Every air arrival into Cambodia also completes a Cambodia e-Arrival card, which is a separate form from your visa. It is 14 fields covering your flight, your accommodation, and a customs declaration, and you submit it within 7 days before your arrival. Filing it through us is $5 USD and checked end-to-end before it reaches Cambodian Immigration, so a single date-format slip does not bounce you at the kiosk.

Think of it as two forms with two jobs. The eVisa answers "may this person enter Cambodia?" and is arranged now, weeks ahead. The e-Arrival card answers "here are this person's arrival details" and is filed in the final week before you fly. Both are mandatory for air arrivals in 2026, and the travelers who plan for both at the start are the ones who walk through the airport without a hitch.

For the full walkthrough of who needs the e-Arrival card and exactly what each field asks for, see our guide on whether you need a Cambodia e-Arrival card as a US air traveler. Pair it with the documents checklist so you have everything ready in one sitting.
