Since 1975, the U.S. has admitted more than 3.3 million refugees, an average of 80,000 per year. From 2012 to 2015, the U.S. admitted 70,000 refugees per year, and in 2016, in response to the global refugee crisis, the U.S. admitted 85,000 refugees. President Obama raised the ceiling to 110,000 in FY17 because he wanted the U.S. to play a leadership role in a humanitarian crisis that has driven the number of refugees to 22.5 million worldwide, the most since the end of World War II. President Trump, however, suspended the program for four months in FY17 and reduced the number of refugees admitted to the U.S.  In FY17 (October 1, 2016 through September 30, 2017), the United States admitted 53,716 refugees and 19,233 Special Interest Visa holders.  President Trump determined that the United States would admit a maximum of 45,000 refugees in FY18 along with 10,000 Special Interest Visa holders.  The 2018 ceiling on refugees is the lowest since the program began in 1980.
