Citizenship Application: Fines
Unless a traffic incident was alcohol or drug related, you do not need to submit documentation for traffic fines and incidents that did not involve an actual arrest if the only penalty was a fine less than $500 and/or points on your driver’s license.

Passport application
Apply for a U.S. passport soon after your naturalization ceremony! Normally you will receive a passport application package along with your ceremony notice. Fill it out before the ceremony and drop it off at the ceremony center. This will save you a lot of time by doing it later at the post office!

During your citizenship interview
If you do not understand the question, instead of guessing what it is, ask the Officer to repeat the question slowly.

On the citizenship interview day
USCIS officers normally are in uniform. Show your respect for the Officer, wear your best clothes for your interview. This will probably be one of the most important interviews in your life!
