This legislation aims to enhance national security by tightening the requirements for individuals seeking U.S. citizenship and the processes for revoking citizenship from those involved in serious criminal activities, particularly terrorism. It introduces a formal declaration that applicants must sign, disavowing any intent to engage in terrorist activities. This attestation must be made under oath, confirming that the applicant has not been convicted of specific terrorism-related offenses and does not intend to commit such offenses in the future.
