What Are ICAO Standards?
ICAO (International Civil Aviation Organization) is the United Nations body that defines international standards for passport photos. All member states, including Vietnam, apply these standards to their citizens' passports.
Why Do ICAO Standards Matter?
A passport photo that doesn't meet ICAO standards can be rejected at borders and embassies, and may cause your visa application to be returned. The biometric recognition systems used at airports require photos to meet specific technical specifications.

How to Take Your Passport Photo at Home
Step 1: Get Your Equipment Ready
- Smartphone: rear camera with 12 MP or higher resolution
- Phone stand: to keep the phone steady and avoid shake
- Lighting: natural light or a white LED lamp
Step 2: Set Up Your Background and Camera
You do not need a real white backdrop. With Ảnh Thẻ's AI you can shoot in front of any background — a colored wall, a window, even outdoors. The system automatically removes the background and replaces it with the ICAO-compliant white.
Tips for Better Photos
- Stand about 50 cm away from the wall to avoid shadows. Face a window so you get even, natural light on your face.
- Camera at eye level: position the phone or stand so the camera is at your eye line — shoot straight on, not looking up or down.
- Shooting distance: stand 0.5 to 1 m from the camera so the frame captures your upper body.
Step 3: Posture and Expression
- Look straight into the camera lens
- Keep your head straight, not tilted
- Open your eyes naturally, no squinting
- Mouth closed, neutral expression
- Shoulders even and relaxed
Step 4: Attire
- Recommended: a collared top in a dark color (navy, black, brown)
- Avoid: white tops (blends into the background), bare-shoulder tops, busy patterns
- Accessories: remove sunglasses, hats, and earphones. Prescription glasses are allowed but must not be mirrored
Important Note
Passport photos require both ears to be visible. If your hair is long, tie it back or push it behind your ears. Religious head coverings are accepted as long as they don't obscure the face.

Common Mistakes to Avoid
- Blurry photo: the camera didn't focus on your face
- Shadows: light from one side casts shadows on the face
- Red eye: direct flash into the eyes
- Cropped ears: the frame is too tight and cuts part of an ear
- Wrong expression: smiling, grimacing or open mouth
