Enhancing Vetting Capabilities and Processes for Detecting Attempted Entry Into U.S by Terrorists-U.S. Presidential Document-09/27/2017

In Executive Order 13780 of March 6, 2017 (Protecting the Nation from Foreign Terrorist Entry into the United States), on the recommendations of the Secretary of Homeland Security and the Attorney General, I ordered a worldwide review of whether, and if so what, additional information would be needed from each foreign country to assess adequately whether their nationals seeking to enter the United States pose a security or safety threat. This was the first such review of its kind in United States history.
