The number of new international students enrolling at United States universities and colleges went down by almost 7% last year, according to official data published this month.

It’s the second year in a row that the number of new international enrolments in the US has declined, denting a market worth $42bn (£33bn) to the US economy last year.

Prof Simon Marginson, of Oxford University, an expert on trends in international students, says there is “little doubt” this downturn is related to the Trump administration.
