Cambodia eVisa Application: Required Documents Checklist for US Citizens

The complete Cambodia eVisa documents checklist for US citizens

Five items. Three are already in your hand, and two you can sort in 90 seconds at your kitchen window. Here is the full list, in the order the application form asks for it, with the specifics Cambodian Immigration enforces and the small mistakes that send a file back to your inbox for a fix.

Passport requirements for Americans

Your current US passport, with at least 6 months of validity remaining from your planned date of entry into Cambodia, and at least 1 full blank page for the entry stamp. If your passport expires in October 2026 and you are arriving in July, you are fine. If it expires in September and you are arriving in July, you are not — the airline will deny boarding at your US departure gate before you ever reach Cambodia. The 6-month rule is enforced by the carrier, not just at the Cambodian border. Our full breakdown of Cambodia passport requirements for Americans covers the validity and blank-page math in detail.

Blank pages catch out frequent travelers. Cambodian Immigration stamps full pages, not strips at the edges. If your passport is busy with Schengen, Japanese, and Mexican stamps, flip through and count. Less than one fully clean page, and you are renewing before you fly. A routine US passport renewal currently runs about 6 to 8 weeks, with expedited service at roughly 2 to 3 weeks, so check the expiry date the day you book, not the week you fly.

Photo specs — the most common correction

A recent passport-style photo, taken in the last 6 months, against a plain white or off-white background. Face fully visible, head centered, neutral expression — no smile, no teeth, no laughing. No glasses, no hats, no head coverings except for religious reasons. JPEG file, under 2 MB, ideally 600×600 pixels or larger. We accept phone photos taken against a white wall, which is how the vast majority of American applicants do it.

Photo corrections are the single most common reason an American application loses a day. The auto-flags are smiles, glasses (any kind, even thin frames), shadows behind the head from artificial light, off-white or colored walls, hats, and resolution under 600×600. None of those are hard to avoid once you know the list — the exact Cambodia eVisa photo size and specs are worth a two-minute read before you upload.

The remaining three items are quick. A clear scan or photo of your US passport bio page — both edges visible, no glare on the laminate, all the machine-readable text legible. A working email address, ideally a personal Gmail, Outlook, or iCloud account, because the approval letter arrives as a PDF and some corporate inboxes silently strip attachments. And a valid payment method — Visa, Mastercard, American Express, PayPal, Apple Pay, and Google Pay are all accepted at checkout.

What is NOT required (and why this surprises Americans)

This is where the Cambodia eVisa parts ways with almost every other visa Americans apply for. The list of things you do NOT need is longer than the list of things you do. Most US travelers coming from an Indian e-Visa, Vietnam eVisa, or Indonesian e-VOA process are pleasantly surprised — and a little suspicious — when they see what Cambodia skips.

• No return flight ticket. Cambodian Immigration does not ask for proof of onward travel at the eVisa stage. You can apply with no flight booked and a tentative arrival date in mind.
• No onward ticket to a third country. Even if your route is Los Angeles → Phnom Penh → onward into Vietnam, you do not need to prove the Vietnam side at the application stage.
• No hotel booking. The form asks for an intended address in Cambodia, but a hotel name and city is enough — no booking reference, no confirmation PDF, no nights-paid evidence.
• No bank statement. Cambodia does not ask for proof of funds for the eVisa. There is no minimum balance, no pay stub request, and no employer letter.
• No itinerary. You do not need a day-by-day travel plan, a tour booking, or evidence of where you will be on day 7.
• No vaccination record. Cambodia has no eVisa-stage health document requirement for US travelers — though CDC travel health still has standing advice on hepatitis A and typhoid worth a five-minute read.
• No travel insurance proof. Insurance is sensible for any American heading to Cambodia, but the eVisa application itself never asks to see it.

The reason all of that is missing is straightforward. Cambodian Immigration treats the visa-fee transaction itself as the commitment — once you have paid for an eVisa, you have skin in the game. The bigger arrival picture (flight number, accommodation address, customs declaration) is collected separately through the e-Arrival Card in the week before you fly. The application stage just asks: who are you, can we see your face, and can you pay? Everything else is handled later.

How to take the perfect passport photo at home

You do not need a drugstore counter, a passport-photo booth, or any specialist gear. A phone camera and a plain white wall is the setup the majority of American applicants use, and it produces a clean compliant photo every time when you follow a short routine. Most travelers do this in 90 seconds at their kitchen window.

Find a plain white wall — interior paint is ideal, but a closed white door or a white sheet pinned flat will do. Stand about 20 inches from the wall, not pressed against it, so there are no shadows behind your head. Face a window where daylight is coming in sideways, not directly behind you, so your face is lit evenly and the wall stays white. Mid-morning or mid-afternoon is best. Avoid late evening, when warm artificial light yellows the wall.

Use the phone's main rear camera, not the selfie camera, and hold it in portrait orientation at eye level. Have someone else press the shutter if you can — arm's-length selfies distort facial proportions and the auto-flagger catches that. Look straight at the lens with a neutral expression. No smile, no teeth, no laughing, and no overly serious face either. Just relaxed. Tuck your hair behind your ears if it covers your face. Take the glasses off. Remove any hat. Take five or six shots and pick the best one.

Save the file as a JPEG, under 2 MB, ideally 600×600 pixels or larger. iPhone and modern Android cameras default to a higher resolution than that — you may need to crop to a square or convert HEIC to JPEG in the Photos app before upload. Do not edit, filter, or beautify the image. The auto-flagger looks for natural skin texture and rejects heavily smoothed photos.

Passport bio-page scan tips

Cambodian Immigration needs to read every detail on your passport bio page — full name, passport number, date of birth, issue and expiry dates, and the machine-readable zone at the bottom. A clean phone-camera scan is fine; you do not need a flatbed scanner. The basics: flat surface, no glare, both edges of the page fully visible in the frame, all text legible.

Put the passport flat on a clean, plain, ideally dark surface — a wooden desk or a black notebook works well, because the contrast makes the page edges clearer for the upload validator. Use daylight from a side window, not the camera flash. Flash bounces straight back off the passport laminate and washes the page out. Hold the phone directly above the open passport, parallel to the page, about a foot away. Tap to focus on the text.

If the laminate is reflecting light back into the lens, tilt the passport very slightly so the reflection moves off to the side — you only need a few degrees. Check the photo before you upload: can you read every letter of your name, every digit of the passport number, and the two lines of < character codes at the bottom? If yes, you are done. If anything is fuzzy, blown out, or cropped, retake. The most common correction on this step is a corner of the bio page falling outside the frame, so leave a thumb-width of margin around all four edges.

Edge cases — green-card holders, dual citizens, minors, name changes

Most Americans fit the standard eVisa box cleanly. A few situations need a closer look before you start, mostly around which passport you use and what name appears on the application.

US green-card holders on a foreign passport apply on the passport they hold, not on their permanent-resident status. A British, Indian, or Filipino citizen living in New York on a green card applies as a Brit, Indian, or Filipino — not as an American. The Cambodian eVisa system reads nationality from the passport, and your green card has no bearing on it. Your eligibility, fee, and processing rules follow the passport, not the residency.

Dual citizens (US + UK, US + Vietnam, US + India, US + Ireland) should apply on whichever passport they plan to enter Cambodia with — and use exactly the same passport for the exit. Switching mid-trip causes problems at the gate every time. The eVisa is tied to the passport number you applied with, full stop.

Minors and newborns each need their own Cambodia eVisa under their own passport. There is no family discount and no shared application. A US baby born last week, traveling with parents, needs a US infant passport first, then their own eVisa. The same five-item document checklist applies, with the same photo specs (yes, including a no-smile passport photo of a six-month-old — it is genuinely the hardest part of the application for new parents).

Name changes after marriage are the other common edge case. The name on the application must match your current passport machine-readable zone exactly — character for character. If you married in 2025 and your passport still shows your maiden name, apply in your maiden name. If you already updated your passport, apply in your new name. Do not mix the two. A name mismatch is one of the avoidable slips we cover in the Cambodia eVisa mistakes to avoid guide, alongside the date-format errors that trip up first-time American applicants.

Putting it together before you apply

Five items, ten minutes, three business days. That is the entire Cambodia eVisa shape for US citizens in 2026. Tourist eVisa $80 USD, Business eVisa $90 USD, both delivered as a printable PDF by email, both with free resubmission if Immigration flags a correction, both backed by US-timezone support. No return flight, no hotel booking, no bank statement, no itinerary. If you want the longer-form version of this list, our Cambodia eVisa documents required for Americans guide lays out every line item.

One reminder before you start. The visa is one form, the e-Arrival Card is a different form, and both are mandatory for every air arrival in 2026. The visa application happens now; the e-Arrival happens within 7 days before you fly. Americans who plan for both at the start avoid the most common 2026 trip-stopper at the kiosk.
