Executive Order 13769
The order said that no more than 50,000 refugees could be let into the United States in fiscal year 2017 until it was deemed to be in the national interest by President Trump. It stopped the U.S. Refugee Admissions Program (USRAP) for 120 days (about four months). After that 120 days, the program would start again for individual countries. The order also stopped the entry of refugees from Syria. The order tells some Cabinet secretaries to stop entry of nationals from countries that do not meet adjudication standards under the Immigration and Nationality Act. The United States Department of Homeland Security lists these countries as Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen.
