From the Document: "On November 1, 2019, President Donald Trump issued a Presidential Determination setting the FY2020 refugee ceiling at 18,000. The refugee ceiling is the maximum number of refugees that can be admitted to the United States in a fiscal year. From the start of FY2020 until the signing of the Presidential Determination, no refugees could be admitted to the United States. The FY2020 refugee ceiling of 18,000 is the lowest in the history of the U.S. refugee admissions program. The Trump Administration has reduced the refugee ceiling each year, setting it at 45,000 for FY2018 and 30,000 for FY2019. These ceilings are much lower than in previous years. Actual refugee admissions in FY2019 totaled 30,000"
