Lying to the FBI and participating in a scheme to conceal material facts from the IRS, FBI, and DHS are also crimes involving moral turpitude. See, e.g., Omagah v. Ashcroft, 288 F.3d 254, 262 (5th Cir. 2002) (observing that courts have almost universally held that "intentionally deceiving the government involves moral turpitude"); Zaitona v. INS, 9 F.3d 432, 437 (6th Cir. 1993) (holding that knowingly making material false statement is a crime of moral turpitude); Matter of B, 7 I. & N. Dec. 342, 343-45 (BIA 1956) (same). In addition, an applicant who commits unlawful acts that adversely reflect on his moral character during the statutory period is barred from establishing eligibility for naturalization, even if not convicted of an offense.
