This bill amends the Immigration and Nationality Act, specifically Section 212(a)(3)(B)(i), to broaden the definition of individuals considered to be engaged in terrorist activity for immigration purposes. It explicitly includes officers, officials, representatives, spokespersons, and members of designated organizations such as Hamas, Palestine Islamic Jihad, Hezbollah, Al-Qaeda, and ISIS , as well as any successor or affiliate groups. Additionally, individuals who endorse or espouse terrorist activities conducted by these organizations will also be deemed to have engaged in terrorist activity. This amendment aims to strengthen U.S. immigration law by ensuring that such individuals are considered inadmissible to the United States.
