On Friday, December 13th, USCIS updated and expanded its policy guidance (PDF) regarding unlawful acts that may prevent an applicant for naturalization to meet the Good Moral Character (GMC) requirements.
Note*: The commission of, or conviction or imprisonment for, an unlawful act, during the statutory period for naturalization, may render an applicant ineligible for naturalization should the act be found to adversely reflect on moral character.
For further details please review the USCIS News Article, “USCIS Expands Guidance Related to Naturalization Requirement of Good Moral Character”.
