Can You Smile in a U.S. Passport Photo?
Yes, but keep it natural. Current State Department guidance says you may smile as long as your eyes are open and your mouth is closed. An exaggerated expression or an open-mouth smile can cause a problem.
A simple way to pose
Face the camera directly, keep your head level, make sure both eyes are visible, and use either a neutral expression or a natural closed-mouth smile.
What ReadyPic can and cannot check
ReadyPic can screen measurable characteristics such as face count, position, image quality, brightness, and background appearance. Expression still requires your own visual review.
ReadyPic is an independent service. It screens technical characteristics but cannot guarantee government acceptance. Confirm current requirements with the U.S. Department of State.
