Frequently asked questions
Common questions about the citizenship test
Quick answers to the most common questions about the USCIS test, Form N-400 and the study paths.
Should I study the 128 questions or the 100 questions?
It depends on the date when you filed Form N-400. If you filed Form N-400 on or after October 20, 2025, you should generally prepare for the 2025 civics test with 128 official questions. If you filed Form N-400 before October 20, 2025, you should generally prepare for the 2008 civics test with 100 official questions. Before memorizing, confirm your case and check the official USCIS information.
What does 65/20 mean for U.S. citizenship?
The 65/20 special consideration may apply to applicants who are 65 years old or older and have been lawful permanent residents for 20 years or more. If you qualify, you may have a reduced civics test and may take it in the language of your choice. Always confirm your case with official USCIS information.
What happens during the USCIS naturalization interview?
During the interview, a USCIS officer may review your Form N-400, ask questions about your application and evaluate your English and civics knowledge. The interview is not only about memorizing answers. You also need to listen, understand, answer calmly and tell the truth about your case.
What should I do if I do not understand the officer?
Do not guess. You can ask the officer to repeat or explain the question. Useful phrases: “I don’t understand.” · “Could you repeat that, please?” · “Could you say that more slowly, please?” · “Can I have a moment, please?”. Practicing these phrases before the interview can help you answer more calmly.
