Belong: US Citizenship Test

Belong helps you prepare for the civics and English parts of the U.S. naturalization test, and for the interview where they are asked.

THE RIGHT TEST FOR YOU
Two civics tests are in use. If you filed Form N-400 on or after October 20, 2025, you take the 2025 test (128 questions to study). If you filed before that date, you take the 2008 test (100 questions). Belong asks when you filed and studies the right list. If you are 65 or older with a green card for 20 years or more, turn on the 65/20 list.

STUDY EVERY QUESTION, FREE
• The civics questions and answers, copied word for word from the official USCIS lists
• A short explanation for each answer, written by Belong and labelled that way
• Flashcards, practice quizzes by topic, and every question read aloud at normal, slower or faster speed
• Readiness, a daily goal counted down to your interview date, and an optional daily reminder

PRACTICE THE INTERVIEW OUT LOUD
The officer reads the questions to you and you answer in English. Belong's mock interview works the same way: each question is read aloud, you answer by voice or by typing, and it stops when the result is settled, as the officer does. You get a clear result with the official answer for anything you missed. Your first mock interview is free.

THE ANSWERS THAT DEPEND ON WHERE YOU LIVE
Enter your ZIP code to see your U.S. senators, representative, governor and state capital. The lookup happens on your phone; your ZIP code is not sent anywhere. Each answer shows the date it was last verified.

THE REST OF THE INTERVIEW
• Reading and writing practice built from the official USCIS vocabulary lists
• The yes/no questions from Form N-400, quoted from the form and read aloud, with the hard words explained. Belong never suggests an answer.

IN ENGLISH OR SPANISH
The whole app is available in Spanish. Test questions and official answers stay in English, as at the interview.
