Significant Transnational Criminal Organization Designation Act

This bill establishes a new process for the Attorney General to designate foreign organizations as "significant transnational criminal organizations" based on their criminal activity affecting U.S. commerce or threatening U.S. security. Members of these designated organizations, as well as their spouses and children who knew about the membership, are barred from entering the United States. The designation process requires congressional notification, allows for review after 2 years, and permits asset freezes of the organization's U.S. assets. Organizations can seek judicial review of their designation, and Congress can revoke designations through a special procedure.
