Why most countries want a neutral face
Facial recognition systems compare your passport photo with your face at the border. A big smile changes the shape of your mouth, cheeks and eyes, which makes the match less reliable. A neutral face is the most consistent reference.
The safe expression
Relax your face, close your mouth and look straight at the camera with both eyes open. Think "calm", not "serious". A very slight natural smile with the mouth closed is fine for US photos.
What doesn't work anywhere
- Teeth showing in a wide grin (outside the US, and risky even there).
- Raised eyebrows or squinting.
- Mouth open.
