The number of international students enrolling in U.S. colleges and universities has tumbled for the second year in a row, a nonprofit group that tracks admissions said Tuesday. Foreign students, who represent an important income stream for U.S. education institutions, are being deterred by a range of factors, including visa and immigration policy changes by the Trump administration, a strong U.S. dollar, Canadian and European competitors, and widespread mass shootings, the Institute of International Education said. The body reported a 6.6 percent slump in 2017-2018 compared with the previous year, which was itself down 3.3 percent from the 2015-2016 academic year.
