Chapter 9 - Good Moral Character
One of the requirements for naturalization is good moral character (GMC). An applicant for naturalization must show that he or she has been, and continues to be, a person of good moral character. In general, the applicant must show GMC during the five-year period immediately preceding his or her application for naturalization and up to the time of the Oath of Allegiance. Conduct prior to the five-year period may also impact whether the applicant meets the requirement.
