The US outperforms other countries in the international student market, the Economist reports, with a share of 22% of international students. But foreign students are just 3.5% of total students on US campuses although the absolute numbers are large. There is scope for raising the latter number. Apparently, it has not happened because US universities are averse to soliciting custom by appointing agents. Universities in other countries have no such qualms, so agents lead students to non-US universities.
The story does not mention this but US universities are also not disposed towards going overseas. The top b-schools do not have many overseas locations. Resistance to foreign entry may be one factor but a more important reason could be that US universities think the best students will come to them anyway, helped by generous scholarships. Another reason could be that faculty and education quality may be difficult to maintain over dispersed locations.
