Not one US university in the Times Higher Education World University Rankings 2015-16 has more than 35 per cent international students, contrasting with institutions in Asia, Oceania and Europe.
An analysis of universities in the rankings shows that 16 of the 30 universities with the highest percentage of international students are in the UK, seven are elsewhere in Europe and four are in Australia or New Zealand.
This may well come as a surprise, since the US has long been a popular destination for teenagers looking to study abroad.
