On March 17, Secretary of State Rex Tillerson issued a cable to all diplomatic and consular posts worldwide calling for the immediate implementation of heightened screening of visa applications.  Through the cable, Secretary Tillerson instructed consular posts to undertake additional screening measures based on the conclusions of the interagency working groups mandated by the President’s Executive Order.  Visa processing screens at U.S. consular posts will be more invasive and time-consuming for certain individuals, particularly those from the countries listed in the President’s most recent Executive Order and those from Iraq.
