10 common mistakes that can cost you your citizenship

It’s just as important to avoid these blunders as it is to study the civics questions. Based on the experiences of hundreds of applicants, here are the most critical mistakes to avoid:

1. Having inconsistencies with your form N-400

This is the most common mistake. During the interview, everything you say must match the information on your N-400 form exactly.

The officer will fact-check your answers against your application. If they notice a discrepancy, they may suspect you of lying, which is a major red flag for USCIS.

Study your application until you know it by heart.

2. Failing to define “yes or no” terms

When an officer asks the “have you ever” questions in part 9, they aren’t just looking for a “yes” or “no.” Often, they will ask you to define a term, such as genocide, torture, or totalitarianism.

They do this to test your English-speaking skills and ensure that you understand what you are testifying to.

Don’t just memorize answers; learn the N-400 questions vocabulary.

3. Answering too quickly

It’s better to pause and think before speaking. If you don’t understand a question, ask the officer to repeat it or speak more slowly.

Officers are required to rephrase or repeat questions to ensure that you understand them.

4. Hiding arrests or criminal records

Ideally, you have a clean record and good moral character. However, if you have any infractions, even minor ones, you must disclose them.

USCIS cross-checks your file with those of other government agencies. If they discover a lie, you could face legal trouble in addition to a denial.

USCIS values honesty and rehabilitation. Show that you have paid your fine, cleared your record, and moved forward.

5. Forgetting your evidence

On interview day, you must bring documents that support your claims. Every statement you make should be supported by evidence. If you forget a document, the officer may issue a Request for Evidence (RFE).

This means you’ll have to return another day, which will significantly delay your case. Double-check your folder before leaving the house.

6. Ignoring the “small talk”.

Your interview starts the moment the officer greets you in the waiting room. From that first “hello,” the officer is evaluating your English comprehension and fluency.

Be prepared to confidently answer casual questions such as “How are you today?” or “What do you think about this crazy weather?”

7. Failing to report recent changes

Your file must be accurate and up to date. If you have moved, changed jobs, traveled abroad, or legally changed your name since filing your N-400, inform the officer immediately.

8. Showing up late

Being late is inexcusable. Officers may view it as a lack of respect for the process.

Aim to arrive at the building 20 to 30 minutes before your appointment. This will give you enough time to pass through security, check in, and catch your breath.

9. Dressing inappropriately for your citizenship interview.

While USCIS doesn’t have an official dress code, first impressions matter.

Avoid wearing jeans, T-shirts, and sneakers. Business casual is your best bet—think slacks and a button-down shirt, a formal dress, or a blouse.

Dress as if you are going to a job interview. This shows respect for the process and marks you as a responsible applicant.

10. Leave your phone on.

Turn your phone off before entering the interview room. Notifications, calls, or texts are highly distracting and disrespectful to the officer.

Note: Recording the interview (audio or video) or taking photos of the office, officer, or documents is strictly prohibited.
