What is N400Test.com?
Everything You Could Possibly Need. All in One Place.
The N-400 is the official application for U.S. naturalization. Passing it requires demonstrating knowledge of civics, U.S. history, and basic English. N400Test.com covers every aspect of that process - the civics test, the English reading and writing portions, the interview questions, and more.

The Problem We're Solving
Citizenship Prep Shouldn't Cost You Anything
Most tools that help immigrants study for citizenship either charge money, collect your data, or give you an overwhelming mess of information. We chose a different path.
The Old Way
- Fragmented PDFs across dozens of government pages
- YouTube rabbit holes with no clear structure
- Expensive prep courses ($99–$300+)
- Confusing USCIS website navigation
- Monthly app subscriptions just to study
- Outdated information with no update dates
- Study materials scattered in multiple languages
N400Test.com
- One clean, organized place for everything
- Always free - no credit card, no trial
- Sourced directly from official USCIS materials
- Regularly updated as USCIS policies change
- Works on any device, no app download needed
- No account, no login, no tracking
- Built and maintained by people who went through it
