The main purpose of this legislation, known as the "No Passports for Terrorists and Traffickers Act," is to enhance national security by allowing the U.S. government to deny or revoke passports for individuals connected to foreign terrorist organizations. The objective is to prevent those who support terrorism from traveling abroad and potentially engaging in harmful activities. Key provisions of the law include the authority for the Secretary of State to refuse passport issuance to individuals who have been charged with or convicted of specific terrorism-related offenses.
