If you studied for the citizenship test using an old study guide, stop. The civics test changed, and the version you take depends on when you filed.
What changed
Applicants who file Form N-400 on or after October 20, 2025 take the 2025 civics test. It is an oral test of 20 questions drawn from a bank of 128, and you must answer 12 correctly to pass.
That is a meaningful jump from the older format. More questions asked, a larger bank to study, and a higher number you need to get right.
The 65/20 exception
If you are 65 or older and have been a lawful permanent resident for 20 years or more, you take a reduced test: 10 questions from a specially selected bank of 20. You also get two attempts at the English and civics portions.
The rest of the requirements
The test is only one piece. To naturalize you generally must:
- Be at least 18 when you file
- Have been a lawful permanent resident for at least 5 years, with continuous residence
- Read, write and speak basic English
- Demonstrate good moral character for the five years before filing
- Show attachment to the principles of the U.S. Constitution
Where cases actually go wrong
In practice, the civics test is rarely what sinks an application. Problems more often come from the good moral character requirement or from continuous residence — long trips abroad, an old arrest, unpaid taxes, or a selective service issue.
Those are worth reviewing before you file, because filing an N-400 puts your entire immigration history in front of an officer.
If anything in your history gives you pause, have it reviewed first. It is far easier to address a problem before filing than after.
