Data from the Association of International Educators shows a growing dip in enrollment of international students in postgraduate programs at U.S. universities and colleges. Visa revocations under President Trump’s administration of students who are not U.S. citizens are apparently a cause of the decline. Many of these students in science, technology and engineering fields have been hired for jobs or had interviews with tech companies, notes Trevor Thornton, a professor in the School of Electrical, Computer and Energy Engineering, part of the Fulton Schools. The situation is especially disturbing to foreign students who are in the early years of their college education in the U.S., he says.
