This about the 7 countries
*Bonus: Obama’s “seven countries” taken out of context: Trump’s claim that the seven countries listed in the executive order came from the Obama administration is conveniently left unexplained. A bit of background: soon after the December 2015 terror attack in San Bernadino, President Obama signed an amendment to the Visa Waiver Program, a law that allows citizens of 38 countries to travel to the United States without obtaining visas (and gives Americans reciprocal privileges in those countries). The amendment removed from the Visa Waiver Program dual nationals who were citizens of four countries (Iraq, Iran, Sudan, and Syria), or anyone who had recently traveled to those countries. The Obama administration added three more to the list (Libya, Somalia, and Yemen), bringing the total to seven. But this law did not bar anyone from coming to the United States ( my emphasis ). It only required a relatively small percentage of people to obtain a visa first. And to avoid punishing people who clearly had good reasons to travel to the relevant countries, the Obama administration used a waiver provided by Congress for certain travelers, including journalists, aid workers, and officials from international organizations like the United Nations.
