DHS Sec. Kirstjen Nielson announced new risk-based measures to enhance national security in the U.S. Refugee Admissions Program (USRAP) through intensified screening of foreign nationals from 11 high-risk countries. The 90-day review came in response to Section 3 of Pres. Trump's executive order last January, which required that the DHS Secretary, the Secretary of State, and the Director of National Intelligence work together to determine whether or not any actions taken to address refugee admissions security risks should be terminated or modified.
