This bill seeks to amend the Immigration and Nationality Act to broaden the definition of individuals considered to be engaged in terrorist activity. The primary goal is to explicitly include certain individuals associated with designated terrorist organizations within the scope of inadmissibility for immigration purposes. Specifically, the legislation targets officers, officials, representatives, spokespersons, and members of Hamas, Hezbollah, Al-Qaeda, Palestine Islamic Jihad, and ISIS , as well as any successor or affiliate groups. It also extends to individuals who endorse or espouse terrorist activities conducted by these organizations, ensuring they are deemed engaged in terrorist activity under U.S. immigration law.
