How the Mexican visa photo process works
A Mexican visa photo is 35×45 mm on a plain white background, with the head measuring 30–36 mm from chin to crown and the face uncovered so both ears are visible. The expression must be neutral and the head straight, looking directly at the camera. The same general framing is widely used for Mexican consular and immigration paperwork. Snapfora sizes to 35×45 mm and shows the 30–36 mm head band so the photo matches the Mexican requirement rather than a generic passport crop.
