Plain white, evenly lit, no shadow behind the head. That is the entire Cambodia eVisa photo background rule — and you can hit it with a phone and a white wall in your living room, no studio required.

A plain white or very light off-white background, evenly lit, with no shadow behind your head, no gradient, no pattern, no furniture, and no other people in the frame. The face must be fully visible and centered with a neutral expression. The most common reason an American photo gets flagged is not the wall color — it is a shadow cast on the wall behind the head from overhead or angled light. You fix that by standing a foot or two off the wall and lighting your face from a side window. A phone photo against a white interior wall in daylight meets the rule every time when you follow a short routine. No studio or booth is required.
