Withholding, misrepresenting, or falsifying information may also negatively affect your employment prospects and job status, and the potential consequences include, but are not limited to, removal, debarment from Federal service, loss of eligibility for access to classified information, or prosecution.
Section 1001, which falls under Chapter 47 of the Code, “Fraud and False Statements,” is particularly interesting and worth a quick look.
Section 1001 states that “whoever, in any matter within the jurisdiction of the executive, legislative, or judicial branch of the Government of the United States, knowingly and willfully—(1) falsifies, conceals, or covers up by any trick, scheme, or device a material fact; (2) makes any materially false, fictitious, or fraudulent statement or representation; or (3) makes or uses any false writing or document knowing the same to contain any materially false, fictitious, or fraudulent statement or entry; shall be fined under this title, imprisoned not more than 5 years . . . .”
