미국인을 위한 캄보디아 eVisa 사진 요건: 크기, 배경, 그리고 거부되는 경우

The white-background rule, in plain English

The background is the single thing that gets the most American photos flagged, and it is also the least intuitive, because the wall that looks perfectly white to your eye can read as gray, cream, or even pale blue to the upload validator. Your brain auto-corrects for color temperature; the validator does not. It measures the actual pixels, and warm indoor light turns a white wall a soft yellow that fails the check.

The rule itself is short: a plain white or off-white background, no patterns, no furniture, no other people, and no shadows behind your head. The practical challenge is hitting "true white" in your own home. Two things fix it almost every time — the right wall and the right light.

For the wall, use a clean white interior wall, a closed white door, or a white sheet or poster board pinned flat. Avoid anything cream, beige, or eggshell — those are exactly the off-white tones the validator reads as gray. For the light, shoot in daylight, not under warm lamps. Stand a foot and a half from the wall so your body does not cast a shadow onto it, and face a window so the light comes from the front or the side rather than from behind you. Mid-morning or mid-afternoon gives the cleanest white. Evening lamps are the most common reason an American photo comes back with a "background not uniform" flag.

One more background trap: standing too close to the wall. A head shadow on the wall behind you reads as a second tone and fails the uniform-background check just as surely as a colored wall does. Step forward, soften the light, and the shadow disappears.

The eight things that get an American photo rejected

The upload form runs an automatic check on your photo before submission, and the same handful of issues account for nearly every flag on US applications. The photo is just one of the broader reasons a Cambodia eVisa gets rejected, but it is the most common, and none of these are hard to avoid once you know the list — they just need a second look before you hit upload.

• A smile. Americans are conditioned to smile for the camera, so a neutral expression feels unnatural — but any smile, even a slight one with no teeth, gets flagged. Relax your face completely, eyes open, mouth closed.
• Glasses. Any frames at all, including thin wire rims and reading glasses, are rejected. Take them off for the photo, even if you wear them every day.
• Off-white or warm-lit backgrounds. A wall that looks white to you can read as gray or cream to the validator, especially under indoor lamps. Shoot in daylight against true white.
• Shadows behind the head. Standing too close to the wall, or lighting from one harsh side, throws a shadow the check reads as a non-uniform background. Step forward and use soft side daylight.
• Low resolution. Anything under 600 pixels on the short side is flagged. This usually means the photo was forwarded through a messaging app that compressed it — upload the original file.
• Wrong file format. An iPhone HEIC file the form will not accept, or a screenshot saved as PNG. Export a real JPEG before you upload.
• Hats, head coverings, or hair across the face. The full face has to be visible from the top of the forehead to the chin. Head coverings worn daily for religious reasons are allowed, but the full face must still show.
• Filters and beauty mode. Heavily smoothed skin reads as a manipulated image and gets bounced. The validator looks for natural skin texture, so turn off any automatic enhancement.

If a photo does get flagged, it is not a denial and it is not the end of your application — you simply re-upload a corrected version, at no extra charge, and the clock keeps running. Our guide to fixing a rejected Cambodia eVisa photo walks through each flag and the exact correction, and the photo sits alongside your passport scan and email inside the full required documents list for Americans if you want to see where it fits in the bigger application picture.

Shooting a compliant photo at home in five minutes

A phone camera and a plain white wall is the setup most American applicants use, and it produces a clean compliant photo every time when you follow a short routine. No booth, no print, no paid service — five minutes at a sunny window does it.

Find a true white wall, a closed white door, or a white sheet pinned flat. Stand about a foot and a half from it, not pressed against it, so there are no shadows behind your head. Face a window where daylight comes in from the side or front, not directly behind you, so your face is lit evenly and the wall stays white. Mid-morning or mid-afternoon is best; avoid evenings, when warm indoor light turns a white wall yellow.

Use the rear camera, not the selfie camera, and hold the phone in portrait orientation at eye level. Get someone else to press the shutter if you can — arm's-length selfies distort facial proportions and the validator catches that. Look straight at the lens with a relaxed, neutral expression. Take the glasses off, remove any hat, and tuck your hair behind your ears if it covers your face. Shoot five or six frames and pick the best one.

Then crop to a square in the Photos app so your head is centered with a little headroom, confirm the file is a JPEG under 2 MB, and you are done. Do not run it through a filter or beauty mode — the validator looks for natural skin texture and rejects heavily processed photos. iPhone users: this is the moment to convert HEIC to JPEG if you did not change the camera setting first.

Edge cases: kids, infants, glasses, and head coverings

Most American applicants fit the standard photo box cleanly. A few situations need a second of thought before you shoot, mostly around children and the no-glasses rule.

Children and infants each need their own Cambodia eVisa under their own passport, which means their own photo to the same spec — white background, neutral expression, full face visible, no smile. Yes, that includes a no-smile photo of a six-month-old, which is genuinely the hardest shot in any family application. Lay the baby on a plain white sheet and shoot straight down from above; the sheet becomes the background and the angle keeps shadows off. Eyes open is the goal, but a calm, neutral expression is what the check is really after.

Glasses come off for everyone, full stop — even prescription lenses worn all day. There is no medical exception in the spec, so take them off, shoot the photo, and put them back on. If you wear a head covering daily for religious reasons, that is allowed, but your full face has to be visible from the top of the forehead to the chin, with no shadow across the eyes.

A few smaller things people ask about: uniforms and white shirts are fine as long as they do not blend into the white background and erase your shoulder line — wear a darker top if you can. Earrings and everyday jewelry are fine. Visible hearing aids and medical devices are fine. The check is about a clear, recent, unobstructed view of your face on a uniform white background, nothing more.

Get the photo right, then apply

The photo is the one field worth a careful second look before you submit, because it is the field most likely to send a file back. Spend the extra two minutes: true white wall, daylight, neutral face, glasses off, square JPEG under 2 MB, and confirm it is not a stray HEIC. Get those right and the photo clears on the first pass.

Once the photo is sorted, the rest of the eVisa is light. Tourist eVisa is $80 USD all-in, Business eVisa is $90 USD all-in, both approved in 3 business days and delivered as a printable PDF by email, both with free resubmission if Immigration flags a correction, and both backed by US-timezone support. There is no return flight, hotel booking, or bank statement to upload — the photo and your passport scan do most of the work.
