Ein einfacher weißer Hintergrund, ein neutraler Gesichtsausdruck, keine Brille und ein JPEG unter 2 MB. Das ist praktisch die gesamte Cambodia eVisa-Fotospezifikation für US-Bürger im Jahr 2026 — und Sie können es zu Hause mit Ihrem iPhone in zwei Minuten aufnehmen. Hier sind die genauen Zahlen und die Routine, die beim ersten Versuch funktioniert.

A recent (last 6 months) passport-style color photo against a plain white or off-white background, showing your full face, head centered, with a neutral expression — no smile, no glasses, no hats or head coverings except for religious reasons. Submit it as a JPEG under 2 MB, ideally 600×600 pixels or larger and roughly square. You do not need a professional booth or a printed photo: a phone camera against a white wall in daylight produces a compliant image, which is how most American applicants do it. The most common reasons a photo gets flagged are smiles, glasses, off-white walls, shadows behind the head, and low resolution.
The Cambodia eVisa photo is the single field most likely to cost American applicants a day. Not because the rules are unusual — they are almost identical to a US passport photo — but because the upload validator is picky about exactly the things people forget: a stray smile, thin-framed glasses, a wall that looks white to your eye but reads cream to the camera. Get those right and the photo clears on the first try. Get one wrong and your file bounces back to your inbox for a retake.
Here is the entire specification in one breath. A recent color photo, taken in the last 6 months, passport-style, against a plain white or off-white background. Your full face visible and centered, eyes open and looking at the lens, neutral expression with no smile and no teeth. No glasses, no sunglasses, no hats or head coverings except those worn daily for religious reasons. Submit it as a JPEG, under 2 MB, ideally 600×600 pixels or larger and roughly square. That is the whole list.
The thing to understand first: you are uploading a digital file, not printing a card. Americans who grew up handing a photographer a 2×2 inch print sometimes overthink this. Cambodian Immigration reads the image you submit by its pixels and its file size, so those are the numbers that matter. The physical "passport size" you may have seen quoted is just shorthand for the framing — head and shoulders, face filling most of the frame.
Target a square or near-square image of at least 600×600 pixels. Larger is fine; the validator wants enough resolution to read your face clearly, and it rejects anything noticeably below that. Crop so your head and the top of your shoulders fill the frame, with a little space above your hair — the same crop you would use for a US passport photo. Save it as a JPEG. The file must come in under 2 MB, which is comfortably above what a cropped phone photo weighs, so size is rarely the problem once you have cropped properly.

Background is where most American photos go wrong, and it is the easiest thing to fix. The requirement is a plain, light, even background — white or off-white, no patterns, no furniture, no doorframes, no posters behind your head. The validator wants a clean separation between your face and the wall, and anything busy behind you reads as clutter that can mask the edges of your head.

Erste Reise nach Kambodscha? Hier ist die ehrliche Checkliste für Erstbesucher aus Amerika — das Visum, die US-Dollar-Geldbesonderheit, die Sicherheitsrealität, die Impfungen, der Tempel-Kleidungsstil und wie die Ankunft am neuen Flughafen im Jahr 2026 tatsächlich aussieht.
Alle sieben Landgrenzen zwischen Thailand und Kambodscha sind seit Juni 2025 geschlossen, daher ist in 2026 der einzige Weg für Amerikaner, von Thailand nach Kambodscha zu gelangen, das Flugzeug. Hier erfahren Sie, wie die Routen Bangkok-nach-Siem Reap und Bangkok-nach-Phnom Penh funktionieren, welches Kambodscha eVisa Sie vor dem Boarding benötigen, und warum der alte Poipet-Überlandplan nicht mehr existiert.
Drei Möglichkeiten, die 310 Kilometer zwischen der Hauptstadt Kambodschas und Angkor Wat zurückzulegen: ein $15 Expressbus, ein 45-minütiger Flug oder eine langsame Flussfähre. Hier erfahren Sie, was jede Option für einen amerikanischen Reisenden tatsächlich kostet, wie lange sie dauert und welche zu Ihrer Reise passt.
The catch is that lighting changes what "white" looks like to the camera. A genuinely white wall photographed under warm evening lamplight comes out cream or yellow, and that off-white cast is one of the most common silent rejections. Shoot in daytime with natural light. Stand about two feet from the wall, not pressed against it, so your body does not throw a shadow onto the background behind your head. Face a window so daylight hits your face from the front or side, never with the window directly behind you, which turns you into a silhouette.

You do not need a drugstore, a booth, or any special gear. A phone and a plain white wall is the setup the majority of American applicants use, and it produces a compliant photo every time when you follow a short routine. Here is the version my team gives travelers who call in unsure.
Find a plain white wall — interior paint is ideal, but a closed white door or a white sheet pinned flat works. Stand about two feet in front of it, not against it, so there are no shadows behind your head. Position yourself so daylight from a window lands on your face from the front or the side. Mid-morning or mid-afternoon gives the cleanest light; avoid evening, when warm bulbs yellow the wall.
Use the rear camera, not the selfie camera — the front camera distorts facial proportions and the validator catches that. Hold the phone in portrait orientation at eye level, and have someone else take the shot if you can, since an arm’s-length selfie warps your features. Look straight at the lens with a relaxed, neutral face. No smile, no teeth, no exaggerated serious look either. Take the glasses off, remove any hat, tuck your hair behind your ears. Shoot five or six frames and pick the cleanest one.

Photo rejection is the single most common reason an American application loses a day, and almost every case traces back to the same short list. My desk logs every flag the upload validator raises, and here is what actually trips Americans up, in rough order of frequency.

Most American applicants fit the standard photo rules cleanly. A handful of situations come up often enough on my desk to be worth calling out before you shoot.
Babies and young children each need their own Cambodia eVisa, with their own photo, on the same neutral-expression, white-background rule as adults. That is genuinely the hardest part of the application for new parents — a no-smile photo of a six-month-old who cannot hold their head up. Lay the child on a plain white sheet and shoot straight down, with no other person, no toy, and no hand visible in the frame. Eyes open if you can manage it; a calm, relaxed expression is what you are after.
Glasses come off, full stop — including for travelers who wear them every waking hour. There is no medical exemption in the current spec, so take the shot without them and put them straight back on. For religious head coverings worn daily, you may keep them on, but your full face from the bottom of the chin to the top of the forehead must be clearly visible, with nothing shadowing your features. Beards and facial hair are fine and need no special handling — just keep the neutral expression and the even lighting.
Once your photo passes the upload check, it travels with the rest of your application and you do not think about it again. If it is flagged, you get an email with a clear, specific list of what to re-upload — usually a fresh shot against a white wall, or a JPEG instead of a HEIC. There is no extra charge to fix it. Free resubmission is part of the all-in price, and the moment you reply with a corrected photo the 3-business-day clock keeps running. You are not penalized for needing a second go at the upload.
