"Foreign-born militant Islamic terrorists have used almost every conceivable means of entering the country. They have come as students, tourists, and business visitors. They have also been Lawful Permanent Residents (LPRs) and naturalized U.S. citizens. They have snuck across the border illegally, arrived as stowaways on ships, used false passports, and have been granted amnesty. Terrorists have even used America’s humanitarian tradition of welcoming those seeking asylum."
