Passport Photo Expression Rules 2026 – Why Neutral Is Required
Smiling, squinting, or any non-neutral expression is a leading cause of passport photo rejection. ICAO Doc 9303 defines the required facial expression precisely — and there is a technical reason behind every rule. This guide explains what a neutral expression actually means, why smiling is prohibited, how the rules apply to children and infants, what makeup is acceptable, and which countries have slightly different standards.
Quick summary
ICAO requirement: neutral expression, mouth closed, both eyes fully open and looking directly at the camera. No smiling, no squinting, no raised eyebrows. Children under 12 months have relaxed rules. Everyday makeup is permitted.
The ICAO Expression Standard
ICAO Doc 9303 Part 3 defines the facial image requirements for biometric travel documents. The expression standard is:
- Expression: Neutral. No smile, no frown, no exaggerated expression.
- Mouth: Closed. Lips in a natural resting position. Teeth must not be visible.
- Eyes: Fully open. Looking directly at the camera. Both eyes clearly visible.
- Eyebrows: In a natural resting position. Raised eyebrows are tolerated if that is the applicant's natural expression.
- Gaze: Directed straight at the camera lens. No looking up, down, or to the side.
Why Smiling Is Prohibited
The restriction on smiling is not aesthetic — it is technical. Automated facial recognition systems used at e-gate border controls work by mapping fixed landmarks on the face: the corners of the eyes, the nose tip, the mouth corners, and the chin outline. A smile distorts all of these measurements simultaneously:
- Raised cheeks push up the lower eyelids, narrowing the eye opening.
- Corners of the mouth shift outward, changing the mouth-landmark coordinates.
- Cheek volume increase alters the midface geometry used in 3D face matching.
A photo taken with a smile may match poorly with a neutral-expression live capture at the e-gate, causing the system to flag the traveller for additional manual checks. Requiring a neutral expression at enrolment ensures the stored biometric template matches the real-time scan as closely as possible.
Eyes: Open, Directed, and Visible
Both eyes must be fully open and clearly visible. The following are grounds for rejection:
- Squinting: Partially narrowed eyes, whether from strong light or deliberate expression.
- Blinking: Even a partial blink at the moment of capture.
- Eyes looking sideways: The gaze must be directed straight at the lens.
- Glare or reflections obscuring the iris from glasses (which are now banned in most jurisdictions in any case).
If you have a medical condition such as ptosis (drooping eyelid) that makes it impossible to fully open both eyes, some passport authorities accept a supporting letter from a doctor. Contact the relevant authority before your application.
Children and Infants: Relaxed Expression Rules
ICAO acknowledges that very young children — especially those under 12 months — cannot reliably hold a neutral expression. Most passport authorities apply relaxed expression rules for infants:
- A slightly open mouth is generally tolerated for babies under 12 months.
- Eyes that are partially open are accepted if the infant cannot hold them fully open.
- A relaxed or sleepy expression is accepted for newborns.
The non-negotiable requirements even for infants are:
- The child's face must be fully visible and centred.
- No parent, guardian, hand, or toy visible in the frame.
- White background (same as the adult requirement).
For older children (typically over 3–4 years of age), the standard ICAO neutral expression requirement applies.
Country exception: Canada and Australia
Canada's IRCC and Australia's DFAT have historically permitted a slight natural smile in passport photos, provided the mouth remains closed and both eyes are fully open. However, facial recognition systems work best with a neutral expression, and automated photo checkers may flag a visible smile. A neutral expression remains the safest choice even for Canadian and Australian applications.
Makeup: What Is and Is Not Permitted
Permitted
- Foundation and concealer at normal coverage levels.
- Eye shadow, mascara, and eyeliner in natural tones.
- Lipstick in any natural colour.
- Contour and highlight at a level that does not visibly reshape facial structure.
- Eyebrow fill and shaping.
Not permitted
- Heavy contouring that alters the apparent shape of the nose, jaw, or cheekbones.
- Face paint or theatrical/costume makeup.
- Filters or beauty retouching applied digitally after the photo is taken.
- Prosthetics or any cosmetic item that changes the structure of the face.
Frequently Asked Questions
Can I smile in a passport photo?
Under ICAO standards, smiling is not permitted. A neutral, relaxed expression with the mouth closed is required. The restriction exists because smiling distorts facial geometry — raised cheeks and narrowed eyes — which reduces the accuracy of facial recognition algorithms at automated border e-gates.
What exactly is a "neutral expression"?
A neutral expression means: mouth closed (teeth not visible), lips in a natural resting position, eyes fully open and looking directly at the camera, eyebrows in a relaxed natural position. You should look alert and natural, not forced or strained.
Will my passport photo be rejected if I am squinting?
Yes. Both eyes must be fully open, clearly visible, and directed at the camera. Partially closed eyes — whether from squinting, blinking, or drooping — are grounds for rejection. If you have a medical condition, contact the issuing authority before applying.
What are the expression rules for infants and babies?
Children under 12 months are subject to relaxed expression rules. A slightly open mouth and partially open eyes are generally tolerated. The face must still be fully visible and centred, with no parent or object in the frame.
Is makeup allowed in a passport photo?
Yes, everyday makeup is permitted provided it does not significantly alter the structure of your face. Heavy contouring, face paint, and theatrical makeup are not permitted. Digital filters or retouching are also not allowed.
Do any countries allow smiling in a passport photo?
Canada and Australia have historically tolerated a slight natural smile with the mouth closed. However, even in those countries, facial recognition systems work best with a neutral expression. A neutral expression is the safest choice for any country.
Always verify current expression requirements with the official authority for your document. ICAO standards and country-specific rules may be updated without notice.
