Yes, U.S. citizens need a visa to enter Cambodia. The State Department's Cambodia advisory confirms that a visa is required. You have two routes: apply online for the eVisa before you fly, or get a visa when you arrive. The official eVisa costs $30 for a tourist visa, and your passport must be valid for at least six months beyond your arrival date. This guide covers both routes, what to prepare, and what the honest trade-offs are.
TL;DR
- U.S. citizens need a visa for Cambodia. The official eVisa is the safer route if you want certainty before you board.
- The tourist eVisa costs $30 and the business eVisa $35. Processing takes up to three business days, per the official e-Visa portal.
- Your passport needs six months of validity past your arrival date, plus passport-sized photos.
- Every traveler must also complete the Cambodia e-Arrival declaration. Submit it within 7 days before you land.
- A tourist visa can be extended once, for one month. Overstays cost $10 per day.

Do U.S. citizens need a visa for Cambodia?
Yes. Americans cannot enter Cambodia on a passport alone. The State Department's travel advisory states that a visa is required for entry, and it lists the same two paths most travelers use: get an e-Visa online ahead of time, or obtain one on arrival.
There is no 90-day or 30-day visa-free allowance for U.S. passport holders. If you are used to Europe or parts of Latin America, this is the main surprise. Plan the visa the same way you plan your flight.
Two other points belong on your checklist from day one:
- Passport validity. Your passport must be valid six months beyond your arrival date. The State Department advisory lists this, and so does the U.S. Commercial Service's Cambodia guide.
- Photos. All visa methods require passport-sized photos. If you need a refresher on sizing, see our U.S. passport photo size guide. Cambodia has its own photo requirements, so confirm the size on the official portal before you print.
Cambodia eVisa vs. visa on arrival
Both routes get you the same type of tourist visa. The difference is when you sort out the paperwork and how much risk you carry on travel day.
| eVisa (apply online) | Visa on arrival | |
|---|---|---|
| Where you apply | Official government portal | At the airport or border checkpoint |
| Tourist fee | $30 | $30 |
| Business fee | $35 | $35 |
| Timing | Apply ahead; approval takes up to 3 business days | Handled on the spot |
| Main advantage | You know the outcome before you fly | No advance application |
| Main risk | Small typo can cause delays | Queues; airline may question boarding without a visa |
Fees for the eVisa come from the official portal. Fees for visa on arrival come from the U.S. Commercial Service guide, which lists tourist visas at $30 and business visas at $35.
You may see other prices quoted on third-party sites, sometimes $35 for a tourist visa or an added handling charge. Treat the official portal as the authority and check it on the day you apply. Fees change, and some outside sites add their own service charges on top of the government fee.
Why we lean toward the eVisa
The visa on arrival works. The U.S. Commercial Service says Americans can get one at the Phnom Penh, Siem Reap and Sihanoukville airports and at major border crossings. But Cambodia's own foreign ministry advises travelers who cannot get a visa ahead of time to verify with their airline whether boarding without a visa is permitted. That is the honest weak spot. A check-in agent in the U.S. who sees no visa in your records may hesitate, and you do not want to argue about it at the counter.
With the eVisa, you arrive at check-in with approval in hand. That is why it is our default recommendation for a first trip.
What changed in October 2026
Cambodia's foreign ministry states that, effective October 3, 2026, the country moved to a fully digitalized visa system. Physical adhesive visa stickers in passports are eliminated for visa categories.
What this means for you in practice:
- Do not expect a sticker in your passport after entry.
- Keep your approval and e-Visa certificate where you can reach them, on your phone and as a paper copy.
- Expect the officer to check your record electronically. Check the official portal for the exact wording of the current process before you go.
Rules in this area are updated often. If anything in this article conflicts with the portal, follow the portal.
How to apply for the Cambodia eVisa step by step
The only site you need is the government's own portal at evisa.gov.kh. The process there is a secure online form, then confirmation and payment, then an approval letter.
Before you start
Gather these items first so you can finish in one sitting:
- Your passport, with at least six months of validity after your arrival date
- A digital passport-style photo
- A credit or debit card for the fee
- Your arrival date and basic itinerary details
- An email address you check regularly
The steps
- Open the official portal. Type the address yourself rather than clicking an ad. Many lookalike sites charge extra fees for filling in the same form.
- Choose the visa type. Tourist is $30. Business is $35.
- Fill in the form. Enter your name, passport number and dates exactly as they appear on your passport. A mismatch is the most common reason for a delay.
- Upload your photo and passport page.
- Confirm and pay. Review everything before you submit.
- Wait for approval. The portal states approval within three business days. You then receive an e-Visa certificate to show immigration.
- Print it. Carry a paper copy and keep a digital one.
The Department of State's advisory says travelers can also apply online 7 calendar days ahead. Since processing can take up to three business days, we suggest you apply at least two weeks before departure. A buffer costs nothing, and it covers a weekend or a Cambodian public holiday.
How long is the eVisa valid?
The official portal says the e-Visa is valid for three months. That is the window in which you must enter the country. It is not the length of your stay. Check the portal for the stay length that applies to your visa type, and plan your itinerary around it.
Cambodia e-Arrival: the second form people forget
The visa is not the only thing you need. The State Department says all travelers are required to fill in the Cambodia e-Arrival declaration, and it recommends submitting online within 7 days before arrival.
Treat it as a separate task from the visa:
- It is a digital arrival declaration, not a visa.
- Approval of your eVisa does not complete it.
- Do it once your travel dates are final, inside that 7-day window.
- Save the confirmation. You may be asked to show it with your passport.
If you are flying through Bangkok or Ho Chi Minh City, you may also need to check the rules there. See our guides on Thailand visa rules for U.S. citizens and the Vietnam eVisa for U.S. citizens if your route includes a stop or an overland crossing.
Getting the visa on arrival
If you decide to wait, here is how it works in practice.
Where. According to the U.S. Commercial Service, you can obtain a visa on arrival at Phnom Penh, Siem Reap and Sihanoukville airports and major border crossings.
What to bring:
- Passport valid six months beyond your entry date
- Passport-sized photos
- The fee, $30 for tourist and $35 for business, in U.S. dollars
- Your completed e-Arrival confirmation
Our advice for cash. Bring clean, undamaged U.S. bills in small denominations. Torn or heavily creased notes are often refused in Southeast Asia, and a failed payment at the desk is a bad start to a trip.
Our advice for airlines. Before you travel, contact your airline and ask whether it will board you without a visa in your passport or record. Cambodia's foreign ministry itself tells travelers to verify this. If the answer is unclear, apply for the eVisa.
Extending your stay and overstay penalties
A tourist visa can be extended for one month, and only once, according to the U.S. Commercial Service. Business visas have more options: extensions of 1, 3, 6 or 12 months, priced from $45 to $300 depending on length.
If you plan to stay longer than the first period, do not leave it to the last day. Ask your hotel or a licensed local agency about the current process and fees, and give yourself several days of margin.
Overstaying is expensive and slow to fix. The State Department advisory lists these penalties:
- $10 per day overstay fine
- Beyond 30 days: an additional $30 exit visa fee, and processing at the Visa Office in Phnom Penh that takes 2 to 3 working days
That last point can wreck a flight home. A short overstay is a fine. A long one is a trip to a government office before you can leave.
Special situations
Dual citizens
If you hold another passport in addition to your U.S. one, use the same passport for the visa application and for entry and exit. Mixing passports is a common source of problems at immigration. Confirm any dual-citizenship rules on the official portal before applying.
Traveling with children
Every child needs their own passport and their own visa. Each child needs a passport valid six months past the arrival date, so check expiry dates for the whole family before you pay anything. If a child's passport is close to expiring, renewal must happen before the visa application, not after.
Business travelers
The business eVisa is $35. Business visas also have longer extension options, listed above. If your trip is for meetings or site visits, choose the business category from the start so you do not need to convert later.
Safety and registration
The U.S. Commercial Service notes that U.S. citizens may enroll in the Smart Traveler Enrollment Program to receive updated information on travel and security in Cambodia. It is free and takes a few minutes before you leave.
What we think: the perspective from our desk
We write about entry rules every week, and Cambodia is one of the easiest countries in the region to get into once you know the order of operations. The mistakes we see are rarely about the visa itself. They come from three things:
- Passport timing. The six-month rule catches people with a passport that looks fine. If your passport expires within a year of your trip, renew first. If you are short on time, a registered courier service can help with expedited renewal, though the cost is real and you should compare it to your timeline.
- Lookalike websites. Several sites that rank for this topic charge service fees on top of the government fee. Paying one is not illegal, but it is rarely necessary. You can do the form yourself on the official portal.
- Last-minute everything. The visa on arrival is a fallback, not a plan. The cheapest way to avoid stress is to apply early, save the approval, and complete e-Arrival once the dates are fixed.
We do not run a visa service, so we have no reason to push you toward a paid middleman for Cambodia. Where we do point readers to a paid option is passport renewal on a tight deadline, because that is a government process with long wait times and genuine urgency.

Need your passport sorted before Cambodia?
The visa is the easy part. If your passport is expired, expiring within six months of your travel date, or lost, that is what holds up the trip. PassportCenter.ai explains renewal timelines, application steps and eligibility in plain language, and connects you to registered passport courier services if you need expedited help.
Start at PassportCenter.ai to check your timeline before you pay for a visa that depends on a valid passport.

FAQ
Is a visa required for U.S. citizens to visit Cambodia?
Yes. The State Department says a visa is required for entry. You can get an e-Visa online in advance or a visa on arrival. Either way, your passport must be valid for six months beyond your arrival date.
Is the eVisa or visa on arrival better?
For most Americans, the eVisa is better because you have approval before you fly. Fees are the same for a tourist visa at $30. The visa on arrival is workable, but Cambodia's foreign ministry tells travelers to check with their airline about boarding without a visa.
How much does the Cambodia eVisa cost and how long does it take?
The official portal lists $30 for a tourist visa and $35 for a business visa. Processing takes up to three business days. The eVisa is valid for three months. Apply directly on the government site to avoid extra service fees.
Can I extend my Cambodia tourist visa?
Yes, once, for one month. The U.S. Commercial Service reports that tourist visas can be extended a single time. If you stay past your permitted date, the fine is $10 per day, with extra steps and fees after 30 days.
Do I need anything besides the visa to enter?
Yes. You must complete the Cambodia e-Arrival declaration. The State Department recommends submitting it online within 7 days before arrival. It is separate from the visa, so finishing one does not complete the other.
