Yes-or-no questions from Form N-400 are an important part of your U.S. citizenship interview. But it’s not just about answering “yes” or “no”. You also need to understand the meaning and vocabulary behind the questions.
During your citizenship interview, a USCIS officer may ask you to explain a word or phrase from the form. For example, an officer might ask you to define communism. Or what genocide is.
The goal is to evaluate your English, ensure you understand the questions, and have you answer honestly.
If you cannot explain a keyword, or if your answer is wrong, your interview may stop. And you will not be able to move forward.
That’s why we’ve created a complete N-400 glossary in PDF—so you can study and feel prepared for the big day.
N-400 yes no questions vocabulary: What officers ask
The purpose of the N-400 ”Yes or No questions”, also called “Have you ever” questions, is to learn more about you and your past.
There are 37 questions related to your travel history, taxes, and criminal record, military service and group affiliations.
The USCIS uses these questions to confirm that you are a good candidate for citizenship and meet all requirements, especially the one regarding good moral character.
You answered these questions when you completed Section 9 of Form N-400. But during the interview, the officer will ask them again and may ask for more information.
In some cases, the officer may not accept a simple “yes” or “no” answer. They may ask you to explain the meaning of a specific word.
For instance, the officer might first ask if you have ever committed genocide. Then, they may follow up by asking you to define the term.
Officers do this to ensure that you truly understand the question and are not answering automatically or guessing.
At the same time, they are evaluating your English skills to see if you meet the language requirement.
That is why studying these definitions is important.
If you struggle with several vocabulary questions, you could fail this part of the citizenship interview.
To help you prepare, we created a complete PDF guide with N-400 yes/no question vocabulary based on official USCIS guidance.
It includes every definition that may come up during your interview. You can download and print the guide to study at your own pace.
Remember, you do not need to repeat a legal definition word for word. You just need to clearly explain the idea in your own words.
Which terms are most commonly asked during the citizenship interview?
It is important to study the definitions in the guide below. You never know which term a USCIS officer might ask you about.
That said, some terms appear more often than others during citizenship interviews. These terms are worth extra review.
Below, we list the words that applicants say they hear the most.
However, do not rely only on these. Many applicants struggle—or even fail—because they cannot explain a key term.
So, take this seriously and study all the N-400 definitions in our guide.
