N-400 interview practice
The officer asks, out loud. You answer, out loud. Then you see what a good answer sounds like. Forty-eight questions in the order the interview usually goes.
How to use this
Say your real answer out loud before you tap. The sample answers use an invented applicant (Maria, from Guadalajara, married to Carlos, two children, a nursing assistant in Houston); yours will be different, and the point is the shape of the answer, not the words. Short, direct, true. "Have you ever" questions are almost always answered "No," but only if no is the truth: a wrong "no" is the one thing in this interview that can end your case.
The officer is also listening to whether you understand English. If you don't understand a question, say "Could you repeat that, please?" or "Could you say that a different way?" Both are fine and neither counts against you.
What this practice is not
A script. Officers word things their own way and skip what doesn't apply to you. Practice answering the idea, not the sentence. And if any "have you ever" question is truly a "yes" for you, talk to an immigration attorney or accredited representative before your interview, not after.
