Short answer
A US citizenship (naturalization) photo must be 2×2 inches (51×51 mm) on a plain white or off-white background, with the head 1 inch to 1⅜ inches (25–35 mm) from chin to crown. Aim for a recent colour photo (taken within 6 months), a neutral expression, even lighting and no shadows. USCIS forms such as N-400 use the same 2×2 inch photo as a US passport.
Snapport lets you take it at home, set a compliant background and crop to the exact spec, so a self-taken photo still meets the requirement. Always confirm the current official rule before you submit.
What to look for before choosing
- Exact spec: 2×2 inches (51×51 mm) (the #1 rejection reason is the wrong size/crop).
- Background: a plain white or off-white background with no shadows.
- Head/face sizing: the head 1 inch to 1⅜ inches (25–35 mm) from chin to crown.
- Neutral expression, eyes open, no glasses glare or head covering.
- A recent, high-resolution colour photo; verify the latest official rule before submitting.

- Take the shot head-on with Snapport.
