Cambodia has a way of pulling you in before you fully understand it. The floating villages of Tonlé Sap, the riverfront in Phnom Penh, the beaches at Kep — the country rewards the traveller who arrives with genuine curiosity and enough preparation to clear the border without drama. The entry system in 2026 is more digital than it has ever been, more efficient at the airports than the land crossings, and still carrying the kind of unofficial friction at certain overland borders that the Kingdom of Wonder has always been known for. This guide covers all of it.
The Country That Surprises You
Most travellers arrive in Cambodia expecting something similar to Thailand or Vietnam: a recognised system, predictable processing, manageable paperwork. What they find is a country in a genuine transition — modernised airports with streamlined digital entry, land borders that vary dramatically in professionalism and predictability, and a visa system that is more flexible than most people realise once you understand its moving parts.
The headline for 2026 is that the digital entry system introduced in phases through 2024 is now fully embedded at all three international airports. One form, submitted before you fly, replaces the three separate paper documents that travellers used to juggle at the immigration counter. For air arrivals, this has genuinely improved the experience — processing times at Siem Reap have dropped significantly since the system became mandatory. For land arrivals, the picture is different, and the details matter considerably more.
Cambodia is also the country in this series where the gap between the rules on paper and the experience at the border is widest. Knowing that gap exists — and how to navigate it without paying for the privilege — is as useful as any official document checklist.
Do You Need a Visa?
For most Western travellers, yes — but the process is short, cheap, and entirely online if you do it before you travel.
Who is visa-exempt:
A limited number of nationalities enter Cambodia without a visa at all. Most ASEAN member states fall into this category — citizens of Thailand, Vietnam, Malaysia, Singapore, Indonesia, the Philippines, Laos, Brunei, and Myanmar can enter visa-free, typically for 14–30 days depending on nationality. A small number of other countries have bilateral visa-free arrangements with Cambodia.
For everyone else — US, UK, EU, Australia, Canada, and the vast majority of Western passport holders — a visa is required.
The e-Visa (the right choice for almost everyone):
The Cambodia e-Visa is processed entirely online through the official government portal at evisa.gov.kh before you travel. It grants a single-entry 30-day tourist stay and costs USD 30 plus a small processing fee. Applications typically take 3 business days to process, and the approval arrives by email as a PDF to print and present at immigration.
Apply through the official portal only. A significant number of third-party sites with official-looking designs charge USD 50–80 or more for the same application. The Embassy of Cambodia in Washington, D.C. explicitly warns against these look-alike sites. The official portal charges USD 30 for the visa fee plus a small USD 6 processing fee — anything substantially above this is a third-party service.
Who can use the e-Visa at which entry points: this is the most commonly misunderstood aspect of Cambodia’s visa system. The e-Visa is accepted at all three international airports (Phnom Penh, Siem Reap, Sihanoukville) and at selected land border crossings: Bavet (the main Vietnam crossing), Tropaeng Kreal (the Laos crossing), and historically at Poipet and Koh Kong from Thailand — though the Thailand border situation in 2026 is covered separately below. At other land crossings, the e-Visa is not accepted and you must use Visa on Arrival. Confirm e-Visa acceptance at your specific crossing on the official portal before you travel.
Visa on Arrival (the flexibility option):
For travellers who did not apply in advance, Visa on Arrival is available at all three international airports and most major land border crossings. The fee is approximately USD 30 for a tourist visa (T-class) payable in USD cash — bring exact or near-exact change. The process involves completing a paper form, submitting a passport photo (carry one), and paying at the immigration counter.
The practical case for choosing the e-Visa over Visa on Arrival: the e-Visa lets you proceed directly to the immigration counter with documentation already approved, skipping the separate Visa on Arrival queue. At busy airports during peak season, that queue can extend considerably. The USD 6 processing fee is a reasonable price for the time saved and the certainty it provides.
Extending your stay:
A standard tourist visa (T-class) can typically be extended once in-country for an additional 30 days, applied for through the Immigration Department or a licensed visa agent. Long-term visitors and those planning an extended stay often enter on an Ordinary visa (E-class) instead, which offers more extension pathways — EB (business), ER (retirement), ES (student) — depending on purpose. If you are planning a stay beyond 60 days, it is worth understanding the E-class options before you arrive rather than discovering them at an immigration office mid-trip.
The Cambodia e-Arrival Card: One Form, Three Documents
The most significant operational change to Cambodia’s entry process in recent years is the Cambodia e-Arrival (CeA) system, which became fully mandatory on September 1, 2024.
Before the CeA, travellers arriving in Cambodia by air had to complete three separate paper documents at the immigration counter: an immigration form, a health declaration, and a customs declaration. The CeA consolidates all three into a single digital submission completed before departure. It is, in that sense, the most practical improvement Cambodia has made to its border process in a long time — and it is entirely free.
How to submit:
- Official portal: arrival.gov.kh
- Official mobile app: Cambodia e-Arrival, available on iOS and Android
- Both channels are free; the official app also handles the electronic Visa on Arrival workflow
When: Within 7 days before your arrival — not earlier, not at the last minute. The system generates real-time data feeds to immigration and will not accept submissions outside this window.
Who must submit: All travellers entering Cambodia by air — foreign nationals and Cambodian citizens alike, regardless of visa type or nationality. ASEAN nationals entering visa-free still need the CeA. Transit passengers who clear immigration still need it. Diplomatic passport holders still need it. If you are landing at Phnom Penh, Siem Reap, or Sihanoukville, the CeA is required.
Land border exemption: The CeA is currently mandatory only for air arrivals. Travellers crossing at land borders still use paper arrival cards completed at the checkpoint. This may change as the system expands, but as of mid-2026, paper forms remain the standard at land crossings.
What the form collects: Your passport details, visa information, flight number, and your accommodation address in Cambodia for at least the first night. Have your hotel booking accessible before you start — the system requires a specific address.
After submission: You receive a QR code by email confirmation. This QR code is scanned by immigration officers on arrival. Screenshot it immediately and save it offline — airport WiFi at Cambodian airports can be unreliable, and having to load the QR code from a slow connection in a moving immigration queue is avoidable stress. A printed backup is worth the two minutes.
One practical note on corrections: Once submitted, the CeA cannot be edited. If you make a mistake — particularly a passport number error or name mismatch — you must submit a new application entirely. Use the passport auto-fill feature if the app offers it rather than typing manually.
What the Border Actually Asks For
The standard document requirements apply across all entry points, though enforcement varies between airports and land crossings.
Required for all travellers:
- Passport valid for at least 6 months from the date of arrival, with at least one blank page for the entry stamp
- Visa (e-Visa approval letter, or Visa on Arrival documentation), unless visa-exempt
- Completed CeA (for air arrivals) or paper arrival card (for land arrivals)
- Passport photo (always carry at least one — Visa on Arrival processing and occasional secondary checks request them)
Frequently requested:
- Onward or return ticket — not always enforced, but airlines check it more strictly than immigration. Have something showing you plan to leave Cambodia within your permitted stay.
- Proof of accommodation, at least for your first nights
- Proof of sufficient funds — there is no published minimum, but USD 50–100 per day of intended stay is the working benchmark
The USD cash reality: Cambodia’s economy runs primarily on US dollars in tourist transactions, and this extends to many border-related interactions. Visa on Arrival fees are payable in USD. Some fees at land crossings — official and otherwise — are quoted and collected in USD. Bring crisp, clean USD notes in smaller denominations. Torn, heavily marked, or pre-2009 series USD notes are routinely rejected by Cambodian vendors, border cashiers, and even some immigration counters. This is not a bureaucratic rule — it is a street-level reality that surprises travellers who have never encountered it.
Air, Land, and Sea: The Full Picture
By Air — Phnom Penh, Siem Reap, and Sihanoukville
The three international airports handle the majority of first-time visitors and offer the most predictable processing experience. With the CeA submitted in advance, air arrivals at all three airports now move through immigration more efficiently than at any point in Cambodia’s recent history. Peak season at Siem Reap — particularly during Angkor Wat sunrise season, roughly November through March — still generates queues, but the digital pre-clearance has meaningfully reduced average processing times.
Phnom Penh’s Techo International Airport is a relatively new facility that opened in 2023 as a replacement for the old airport, with more modern infrastructure and processing capacity.
By Land — Thailand, Vietnam, and Laos
This is where Cambodia’s entry picture becomes significantly more complex, and where the editorial angle that most travel guides avoid deserves direct coverage.
The Thailand–Cambodia border in 2026: The main overland crossing between Thailand and Cambodia — the Aranyaprathet/Poipet crossing — has been closed since October 2025 due to an escalating border territorial dispute between the two countries. A ceasefire was reached on December 27, 2025, and the security environment has stabilised, but the land crossing remains closed to civilian traffic as of mid-2026. Travellers planning a Thailand–Cambodia overland route should check the current status through official channels before committing to land travel — flights between Bangkok and Phnom Penh or Siem Reap are the reliable alternative for now.
Vietnam crossings: The main crossing is Bavet/Mộc Bài, connecting Cambodia to Ho Chi Minh City. This is one of the highest-volume crossings in the country and generally processes straightforwardly, though queues during peak periods are significant. The Cambodia e-Visa is accepted here, which removes one layer of complication.
Laos crossing: The sole crossing between Cambodia and Laos is Trapaeng Kriel/Nong Nok Kheane, in Stung Treng province. It is a single crossing with no alternatives — if you are doing the Cambodia–Laos overland route, this is it. Processing has improved in recent years and the Cambodia e-Visa is accepted here.
On unofficial fees at land borders: This requires plain language. At Cambodian land border crossings, unofficial fees — requests for payment that have no legal basis — have been a persistent and documented feature of the experience for years. These range from USD 1–5 “overtime fees” on weekends and evenings, to demands for “processing fees” or “stamping fees” at checkpoints where the service is supposed to be free. Government travel advisories from multiple countries, including Canada, explicitly note that some border officials demand extra charges before allowing entry.
The practical advice: the official visa fees are USD 30 for tourist Visa on Arrival — nothing else is officially owed at the border. Any additional payment request is unofficial. Having the e-Visa processed in advance removes the most common leverage point, since your entry document is already approved and the counter interaction is reduced to a stamp. If you are asked for unofficial fees at a land crossing, the amount is typically small; whether you pay or push back is a judgment call based on the specific situation, but knowing it is not official is the starting point.
Avoid through-bus arrangements where the driver collects your passport and handles the visa process on your behalf — this format places you in a group where the path of least resistance is collective payment of whatever fees are requested, official or not.
By Sea
Sea entry to Cambodia is limited and primarily used by cruise ships docking at Sihanoukville or Phnom Penh’s river port. Cruise passengers typically go through group pre-clearance arranged by the operator. Individual sea arrivals by private vessel must clear at designated ports only.
The Details That Catch Travellers Off Guard
The e-Visa Is Single Entry Only
Unlike Vietnam’s e-visa which offers a multiple-entry option, Cambodia’s tourist e-Visa is single entry. If you leave Cambodia and re-enter — for a side trip to Vietnam or Thailand — you need a new visa. Travellers planning multi-country circuits with re-entry to Cambodia should either apply for a new e-Visa for the second visit or enter on a Visa on Arrival. The E-class ordinary visa offers more flexibility and some extension pathways, and is worth considering if your Cambodia itinerary involves exits and re-entries.
The FPCS Registration Requirement
Hotels, guesthouses, and licensed accommodation providers are legally required to register foreign guests in the Foreigner Presence Control System (FPCS) within 24 hours of check-in. This is handled automatically when a hotel scans your passport on arrival — you do not need to do anything separately. If you are staying in a private apartment, with friends, or in an unlicensed accommodation, the registration is the host’s responsibility. This matters in practice because the registration creates the legal record of your presence in Cambodia, and its absence can surface in complications during any immigration-related interaction during your stay.
The Passport Photo You Forgot to Bring
Cambodia’s immigration counters — particularly for Visa on Arrival — periodically request passport photos that are not listed as mandatory in every guide. Border processing systems sometimes photograph you on the spot; sometimes they ask for a print. Carrying two passport-sized photos with a white background costs nothing and removes any uncertainty.
The Customs Declaration Inside the CeA
The CeA consolidates your customs declaration alongside your immigration and health information. This means you are declaring goods, currency, and prohibited items before you arrive, not at the airport on a paper form. Read the customs section carefully before submitting — declaring nothing when you are carrying more than USD 10,000 equivalent creates a discrepancy between your pre-arrival declaration and what inspectors find, which is more complicated to explain than simply declaring it.
Yellow Fever Certificate
The yellow fever vaccination certificate requirement applies in Cambodia on the same terms as the rest of Southeast Asia: if you have been in a yellow fever risk country within 6 days before arriving, you must present a valid certificate at immigration. Transit of more than 12 hours in a risk country triggers this, even if you did not leave the airport. Travellers routing through East Africa, West Africa, or certain South American countries before arriving in Cambodia fall into this category.
Overstay Fines
Cambodia’s overstay penalty is USD 10 per day, applied at the immigration counter when you depart. The fine is manageable in the short term but escalates quickly for extended overstays, and a pattern of overstaying creates complications for future visa applications. If circumstances are pushing you toward an overstay, extending the visa in-country is the correct action — done early enough, it is a straightforward process.
Frequently Asked Questions
Do I need a visa for Cambodia? Most Western passport holders — US, UK, EU, Australia, Canada — require a visa. The e-Visa (USD 30 + USD 6 processing fee, applied online at evisa.gov.kh) is the recommended option for air arrivals. Visa on Arrival (USD 30, paid in USD cash) is available at airports and most land crossings. Most ASEAN nationals enter visa-free.
What is the Cambodia e-Arrival Card and is it really mandatory? The Cambodia e-Arrival (CeA) is a mandatory free digital pre-arrival form required from all travellers entering by air. It consolidates immigration, health, and customs declarations into one submission. Complete it within 7 days of arrival at arrival.gov.kh or via the official mobile app. It is required even if you are visa-exempt or have already processed your visa separately.
Is the CeA required for land border crossings? Not currently. As of mid-2026, the CeA is mandatory only for air arrivals at the three international airports. Land border crossings still use paper arrival cards.
Can I get my Cambodia e-Visa at the border? No — the e-Visa must be applied for online before travel. If you did not apply in advance, Visa on Arrival is available at airports and most major land crossings in USD cash.
Is the Thailand–Cambodia land border open? The main Aranyaprathet/Poipet crossing has been closed since October 2025 due to a bilateral territorial dispute. A ceasefire was reached in late December 2025, but the crossing remained closed to civilian traffic as of mid-2026. Check current status through official channels before planning an overland crossing from Thailand.
Can I re-enter Cambodia on the same tourist visa? No — the tourist e-Visa and Visa on Arrival are single-entry only. A new visa is required for each entry into Cambodia.
What is the overstay penalty? USD 10 per day, collected at immigration on departure.
Do I need to bring a passport photo? Officially optional for e-Visa holders, often requested for Visa on Arrival processing. Carrying two is the simplest solution.
The Bottom Line
Cambodia in 2026 is easier to enter correctly than it has ever been — for travellers who do the preparation. Apply for the e-Visa at the official portal before you travel. Complete the e-Arrival Card within 7 days of your flight. Carry clean USD. Bring a passport photo. Know that land borders carry a different character than airports, and that unofficial fee requests are not official policy.
The temples at Angkor, the history of Phnom Penh, the slow pace of the Mekong towns — none of it is gated behind a complicated entry system. It is gated behind a specific set of details that are entirely manageable once you know them.
This article is the fifth in the series covering entry requirements across Southeast Asia’s major borders.
