What we fix for free, and what AI fixes
Fixed for free
- Background. Replaced with the one this document asks for: white or off-white background.
- Head tilt. Straightened if the head leans slightly to one side.
- Frame. Exactly 51 × 51 mm, by the document’s rules.
- A light shadow on one side of the face. Gently brightened.
- File and print sheet. A file to the document’s rules and a 10 × 15 or A4 sheet to print.
What can't be fixed for free, AI correction fixes
- Hard shadows and uneven light on the face.
- A smile, raised brows or a half-open mouth. Cropping keeps the face it was given.
- Too few pixels. If the original is smaller than 602 × 602 px, enlarging it only blurs the face.
- Clothing and pose. Shoulders out of frame, body turned away from the camera.
Glasses in the frame. This document does not accept them at all — take them off and shoot again.

- Used for N-400 (naturalization) and N-600 (derived citizenship)
- Two enclosed photos are still required from applicants residing outside the United States

What the source confirms
- USCIS tells naturalization applicants to get two passport-style photos taken as part of preparing the application.
- The USCIS naturalization overview also says applicants submit two photos with the application package.
- After USCIS accepts an application, it may send a biometrics appointment notice to collect fingerprints, photo and signature.
- The U.S. Department of State passport-style photo standard is 2 × 2 inches (51 × 51 mm).
- State Department passport-photo rules require a white or off-white background and a recent colour photo.
- The Form N-400 instructions require two identical colour passport-style photographs, 2 by 2 inches, full face and frontal, on a white to off-white background, printed on thin glossy paper and unmounted, under the heading "Photograph Requirements for Applicants Residing Outside the United States".
- The same instructions set head height at 1 to 1 3/8 inches from the top of the hair to the bottom of the chin, and eye height between 1 1/8 and 1 3/8 inches from the bottom of the photo.
- From 12 December 2025 USCIS policy alert PA-2025-29 provides that USCIS will not use or reuse self-submitted photographs, and that Forms N-400 and N-600 require the collection of new biometrics, including a new photograph.
