Which list you study
The current test is the list of 128 questions, and it applies if you filed Form N-400 on or after October 20, 2025. If you filed before that date, you take the older 100-question version. It has its own practice test and question list here: the 100-question 2008 test. How the two versions differ.
Applicants who are 65 or older and have been permanent residents for 20 years or more study a shorter list of 20 questions. Those are marked with an asterisk on the questions page.

Every question comes with the reason behind it
The official list gives you a question and the answers that count. It does not tell you what the answer means, and a memorized answer falls apart the moment the officer asks the same thing in different words. Each question page here adds three things:
- The idea behind the answer, in plain English.
- Why the official answer is the one USCIS accepts, and which other wordings also count.
- Where people get confused, and a hook to keep it straight.
For example, question 28
Why does each state have two senators?
The official list accepts two answers that sound like different facts. They are two names for the same bargain struck at the Constitutional Convention, and once you see the bargain, either answer comes out right.
Where the questions come from
The questions and the accepted answers are reproduced word for word from the USCIS list 128 Civics Questions and Answers, a work of the U.S. federal government. The explanations are written by us. More about the site.
