PATRIOT Act § 411 expands deportability to include endorsement of terrorism, raising First Amendment concerns

President George W. Bush signed the USA PATRIOT Act on October 26, 2001, with Section 411 dramatically expanding immigration grounds for excluding and deporting noncitizens linked to terrorism. The provision made deportable any noncitizen who used a position of prominence to endorse or espouse terrorist activity, or who was a representative of a group whose political endorsement of terrorism undermined U.S. antiterrorism efforts — even if the speech consisted of advocacy for nonviolent political ends. Civil liberties organizations warned that the new grounds effectively imposed guilt by association and punished First Amendment-protected speech by noncitizens. Section 411 amended INA § 212(a)(3) and § 237(a)(4) and was immediately used by DHS to deny visas to foreign scholars, journalists, and activists whose political views were deemed threatening.
