How to make a United States citizenship (n-400) photo in 3 steps

Upload any photo of yourself, and the tool handles the entire United States citizenship (n-400) spec pipeline — background removal, colour swap, spec-exact crop, file-size compression — in one pass.

1

Upload any photo of yourself

Take a photo with your phone or webcam against any background — a plain wall, a cluttered room, an office setting. The AI segments you from whatever is behind you, so you don't need to worry about finding a plain plain white or off-white backdrop before shooting.

2

AI removes the background and applies plain white or off-white

BiRefNet-portrait, the state-of-the-art open-source matting model, removes the original background and composes your face onto the plain white or off-white required for United States citizenship (n-400) applications. Fine details like hair strands and wispy edges are preserved cleanly.

3

Auto-crop to 51×51mm and download

The tool auto-positions your face based on the segmentation mask, applies the exact 51×51mm crop at 300 DPI, and produces a JPEG under 240 KB — the standard file size for United States portal uploads. Drag the crop box if you want to fine-tune the position.

Understanding the United States citizenship (n-400) spec

The United States citizenship (n-400) application requires a 51×51mm colour photograph with a plain white or off-white background at 300 DPI. Photos submitted outside these specifications are the single most common reason for application rejection at the document-verification step. Getting the dimensions, background colour, and file size right the first time avoids the delay and cost of a re-submission.

United States citizenship (n-400) photo FAQ

What are the United States citizenship (n-400) photo dimensions?

United States Citizenship (N-400) photos are 51×51mm at 300 DPI, on a plain white or off-white background. Face must occupy 25-35mm of the frame's height (from chin to top of the head).

What background colour is required for United States citizenship (n-400) photos?

plain white or off-white. Photos on cream, beige, or textured backgrounds are the single most common reason for application rejection at the verification step. This tool automatically replaces whatever background is in your source photo with the correct plain white or off-white colour.

Can I take United States citizenship (n-400) photos with my phone?

Yes. Modern phone cameras produce more than enough resolution and colour accuracy for the 51×51mm output size. What matters is even lighting (no harsh shadows on your face), a plain-ish background (or use this tool to swap the background), and a straight-on, neutral-expression pose.

What is the maximum file size for United States citizenship (n-400) photos?

The standard upload cap for United States citizenship (n-400) portals is around 240 KB. This tool automatically compresses the output JPEG to stay under that cap while preserving the required 300 DPI resolution. If your destination portal has a stricter cap, use our free Image Compressor to shrink further.

Is my uploaded photo saved on your servers?

Your original photo is processed in memory and never persisted on our servers. The AI background removal runs server-side (the model file is 885 MB and doesn't fit in a browser), but the input image is discarded immediately after processing. Only the composited output is returned to your browser, and nothing about your photo is logged, saved, or shared with third parties.

What if the background removal misses part of my hair or clothing?

The BiRefNet-portrait model is trained specifically for people and handles hair, clothing edges, and skin tones cleanly on the vast majority of photos. If you see a specific edge artefact, try re-uploading with better lighting on your subject (indirect natural light works best) or contact us at [email protected] with the source photo and we'll investigate.

Do I need to sign up or pay to use this tool?

No sign-up required for basic use. Guests get 2 passport photos per day; free accounts get 3/day. If you need more (immigration lawyers, HR teams, travel agencies handling volume), Pro at $12/mo unlocks unlimited photos.

Can I print the United States citizenship (n-400) photo at home?

Yes. The output is a 300 DPI JPEG at the exact 51×51mm spec, so any home inkjet or laser printer produces a print at the correct physical size when you print at 100% scale (not "fit to page"). For best results, use matte or semi-gloss photo paper.
