When you are preparing for your U.S. citizenship interview, your mind is probably filled with civics questions, tax records, and N-400 dates. But there is one simple detail that is easy to forget until the night before: What should I wear?
It might seem like a minor thing, but your appearance makes an immediate impression. The USCIS officer evaluating you is assessing your overall eligibility and your respect for the naturalization process. Dressing professionally shows the officer that you take the step of becoming an American citizen seriously.
Here is a practical, down-to-earth guide on how to choose your outfit for both the interview and the Oath Ceremony.
You do not need to buy a three-piece suit or a designer gown. Think of the dress code as "business casual"—the kind of outfit you would wear to a professional job interview or a formal meeting. Here are some simple, reliable options:
You want the officer to focus on your answers, not your clothing. Avoid items that might be seen as too casual or distracting for a formal government proceeding:
If you pass your interview, your next step is the Oath of Allegiance ceremony. While the interview is a one-on-one conversation, the Oath Ceremony is a formal, public court proceeding. Because of this, USCIS has a stricter, official policy for this event.
Your appointment notice (Form N-445) will explicitly request that you dress in proper attire to respect the dignity of the event. USCIS explicitly prohibits jeans, t-shirts, shorts, and flip-flops at the ceremony. Many applicants choose to wear their Sunday best—suits, ties, and formal dresses—to celebrate this major milestone with their families and take photos.
