A flagged photo is the most common reason an American Cambodia eVisa loses a day — and it is almost never the camera. Here are the nine reasons US photos get rejected, the exact fix for each, and how to re-upload a corrected version without missing your flight.

A Cambodia eVisa photo is flagged when the upload check measures something the spec does not allow — most often an off-white or warm-lit background that reads as gray, a smile, glasses, or an overexposed face blown out by bright window light. For US applicants the file format trips people up too, because recent iPhones save HEIC by default and the form wants a JPEG under 2 MB. The fix is the same in every case: reshoot against a true white wall in even daylight, neutral face, glasses off, export a square JPEG, and re-upload. A flagged photo is not a denial and there is no extra charge to correct it — the 3-business-day clock keeps running once the new file is in.
