Those countries (Egypt, Saudi Arabia, Turkey, and UAE) have the infrastructure in place to allow them to identify and screen who is getting on their airplanes perhaps?
You're reaching here. And you left Azerbaijan off the list.
Maybe a little as that was my thought on a possible reason before I actually did a little homework on the subject. Trump didn't hand pick those 7 countries. The Executive Order contains this language:
It says that it seeks “Suspension of Issuance of Visas and Other Immigration Benefits to Nationals of Countries of Particular Concern.” It also says“I hereby proclaim that the immigrant and nonimmigrant entry into the United States of aliens from countries referred to in section 217(a)(12) of the INA, 8 U.S.C. 1187(a)(12), would be detrimental to the interests of the United States, and I hereby suspend entry into the United States, as immigrants and nonimmigrants, of such persons for 90 days from the date of this order.”
The Department of Homeland Security targeted these seven countries over the last years as countries of concern. In February 2016 “The Department of Homeland Security today announced that it is continuing its implementation of the Visa Waiver Program Improvement and Terrorist Travel Prevention Act of 2015 with the addition of Libya, Somalia, and Yemen as three countries of concern, limiting Visa Waiver Program travel for certain individuals who have traveled to these countries.” It noted “the three additional countries designated today join Iran, Iraq, Sudan and Syria as countries subject to restrictions for Visa Waiver Program travel for certain individuals.”
