Science in Trumpland
In an extremely large survey of 49 of the largest physics departments in the country, representing 41% of all enrolled physics graduate students in the United States, an overall decrease of almost 12% in the number of international applicants was observed from 2017 to 2018.
This was a tremendous surprise, as no such study was even planned. The impetus for this study was prompted by a small number of American Physical Society members contacting the Office of Government Affairs to report a substantial decrease in the number of applications from international students.
