H.R. 178 aims to add the following to the list of grounds that a U.S. citizen can lose his or her U.S. citizenship:
Taking an oath or making a declaration of allegiance to a foreign terrorist organization after their eighteenth birthday;
Entering or serving in the armed forces of a foreign state that harbors a foreign terrorist organization;
Accepting or serving in a position within a foreign terrorist organization after turning 18, where the organization requires an oath or declaration of allegiance;
Accepting or serving in a position within a foreign terrorist organization that involves the conscious participation in hostilities against U.S. military or civilian personnel.
The bill also directs the U.S. State Department and the Department of Homeland Security (DHS) to revoke any previously issued passports from any individual engaging in terrorist activities.
