The "Stop Citizenship Abuse and Misrepresentation Act," or SCAM Act, aims to significantly expand and clarify the grounds for civil denaturalization proceedings. Its core purpose is to enable the United States to revoke the citizenship of individuals who, through specific actions, demonstrate they lacked the necessary good moral character, attachment to the Constitution, and disposition to good order at the time of their naturalization. The bill establishes three primary categories of actions that would trigger denaturalization if they occur within 10 years of naturalization. These include associating with a foreign terrorist organization , being convicted of or admitting to fraud against federal, state, local, or tribal governments involving at least $10,000, or being convicted of or admitting to an aggravated felony or espionage offense . These actions are deemed prima facie evidence that the individual's citizenship was obtained by concealment or misrepresentation. Upon denaturalization, the order admitting the person to citizenship is revoked and set aside, and their certificate of naturalization is canceled. This revocation is retroactive , meaning the citizenship is treated as void from its original issue date. Furthermore, any person whose citizenship is canceled under these provisions will be removable through expedited proceedings, regardless of their post-denaturalization immigration status or the time elapsed since naturalization. A fallback provision specifies that if the 10-year period is found unconstitutional, it will revert to a 5-year period. The bill also includes a Sense of Congress stating that a prior Supreme Court ruling on denaturalization effects (Costello v. INS) was misconstrued.
