A citizenship interview is part of the naturalization process, and you must already been a permanent resident of the country. A citizenship interview gives the USCIS agent the opportunity to get to know you. The interview also helps confirm that your application and reason for wanting to become a citizen are valid. The USCIS officer may ask how long you have been in the United States, and how you entered the country. They may also ask if you have a job, if you are married, or if you have children. Other citizenship interview question topics include if you have traveled out of the country or if you have committed any crimes. They will also ask questions designed to determine if you are a risk to the safety and security of the United States. The questions are not particularly difficult or complex, and honest and direct answers are best.
