Can You Smile in a Passport Photo?

It seems like a simple question, but the answer has gotten thousands of passport applications rejected. Smiling - even slightly - can trigger an automatic rejection in countries that use facial recognition scanning. This guide covers the exact expression rules for every major country so you do not waste time and money retaking your photo.

The Short Answer

Here is how the major countries break down:

Why Smiling Is Banned in Most Passport Photos

It is not about being unfriendly. The reason is purely technical: biometric facial recognition.

Modern passports contain a chip that stores a digital version of your photo. When you go through border control, cameras scan your face and compare it to the stored image. The algorithms measure specific distances - between your eyes, from your nose to your chin, the width of your cheekbones.

When you smile, several things happen to your face:

• No Your cheeks push up, changing the distance between your cheekbones and eyes
• No Your eyes narrow slightly (sometimes called "smile eyes")
• No Your jawline shifts as your mouth opens or widens
• No Creases and shadows appear around your nose and mouth

All of these changes make it harder for the scanning system to match your photo to your face. The International Civil Aviation Organization (ICAO), which sets the global standard for travel documents, recommends a "neutral expression" specifically because it produces the most consistent, measurable facial geometry.

This is also why passports from the early 2000s - when smiling was still allowed in many countries - often cause delays at automated e-gates. The photos simply do not match as well.

US Passport Photo Smile Rules

The US State Department is strict and specific. Their official requirement states:

"Have a neutral facial expression or a natural smile with both eyes open."

Wait - did that say "natural smile"? Here is where it gets confusing. The State Department's website updated their wording in recent years, and at different points the language has varied. However, in practice, passport processing centers consistently reject photos where the applicant is visibly smiling. The safest approach - and what every passport photo service recommends - is a completely neutral expression.

For US visa photos (DS-160), the same rule applies. The embassy uses biometric scanning on all visa photos, and a neutral expression is required.

UK Passport Photo Smile Rules

The UK is more relaxed than most countries. The HM Passport Office states:

"You can have a natural smile (but your mouth must be closed). Your face must be clear, and you shouldn't have a frown or squint."

This means a gentle, natural smile is acceptable in UK passport photos - as long as your mouth stays closed and the expression does not distort your features. Think "pleasant face" rather than "say cheese."

However, there are limits. If your smile causes your eyes to narrow significantly or creates deep shadows around your mouth, the photo may still be rejected. The safer approach is a very slight smile or a completely neutral face.

For UK passport photos, the size requirement is 35 x 45mm, and the background must be plain light grey or cream.

Canada Passport Photo Smile Rules

Canada follows the ICAO standard strictly. The official guidance from Immigration, Refugees and Citizenship Canada (IRCC) states:

"A neutral expression (non-smiling) with mouth closed is required."

Canada is known for being particularly strict about photo requirements. Passport photos are rejected at a higher rate than many other countries, and expression is one of the top reasons. Even a hint of a smile can trigger a rejection notice.

The Canadian passport photo must be 50 x 70mm with a plain white or light-coloured background.

Can You Show Teeth in a Passport Photo?

No - there is no major country that allows visible teeth in passport photos.

Even the UK, which allows a natural smile, requires your mouth to be closed. Showing teeth creates significant problems for biometric scanning because:

• No An open mouth changes the measured distance from nose to chin
• No Teeth create a high-contrast area that confuses scanning algorithms
• No The wider the smile, the more your eyes narrow - changing another measured distance

If your photo shows teeth, it will almost certainly be rejected in every country. This is the one universal rule that has no exceptions.

Tips for Getting the Right Expression

Getting a neutral expression that does not look like a mugshot is harder than it sounds. Here are some practical tips:
