9 FAM 40.21(a) N2.1 Evaluating Moral Turpitude Based Upon Statutory Definition of Offense and U.S. Standards - (CT:VISA-753; 06-29-2005)
To render an alien ineligible under INA 212(a)(2)(A)(i)(I), the conviction must be for a statutory offense, which involves moral turpitude. The presence of moral turpitude is determined by the nature of the statutory offense for which the alien was convicted, and not by the acts underlying the conviction. Therefore, evidence relating to the underlying act, including the testimony of the applicant, is not relevant to a determination of whether the conviction involved moral turpitude except when the statute is divisible (see 9 FAM 40.21(a) N5.2) or a political offense (see 9 FAM 40.21(a) N10). The presence of moral turpitude in a statutory offense is determined according to United States law.
