Strategy To Oppose Predatory Organ Trafficking Act or the STOP Organ Trafficking Act This bill authorizes the Department of State to deny issuing a passport to, or to revoke an already-issued passport belonging to, an individual who has been convicted of certain offenses related to acquiring, receiving, receiving, or transferring human organs. The bill expands protections against severe forms of trafficking in persons to include trafficking for the purpose of removing a person's organs. The bill defines such trafficking to include the use of coercion, abduction, or fraud to recruit, transport, or harbor a person for the purpose of removing that person's organs. The State Department shall annually report to Congress on human trafficking conducted for organ tracking purposes, including descriptions of the sources and methods associated with such trafficking, State Department activities to address such trafficking, and activities by other countries to address such trafficking.
