No sector in the UK has more enthusiastically embraced globalisation than higher education. Top universities have erected campuses on other continents, expanded their share of students from abroad, and touted their instruction of ¡°global citizens¡±.

The University of Oxford, for example, that its ¡°international profile rivals that of any university in the world¡±. My own institution itself ¡°London¡¯s Global University¡±.

Such branding doubtlessly appeals to a new footloose class of international elites. Yet as over globalisation surges amid Brexit, UK universities now face their own discontents. This is especially true when it comes to educating ¡°foreign¡± students.

A previous poll has found a sizeable majority of the UK public supports a cap on international students. some university administrators: ¡°Foreign students are being deterred from courses at British universities because of ¡®public paranoia¡¯ over immigration.¡±

Cultural xenophobia may explain some antipathy towards international students. Yet my own with Stanford political scientist Carlos X. Lastra Anad¨®n paints a more complex picture. It seems that the public¡¯s perceived self-interest also plays a pivotal role in shaping attitudes.

We discovered that people were about 15 per cent more likely to favour capping the number of international students when primed to think about them ¡°crowding out¡± domestic students in university admissions. The bottom line: people are more likely to reject international students when they are perceived as a threat to themselves or their children.

Within the ivory towers of progressives, nods to the more intangible benefits of international students ¨C such as diversity and multiculturalism ¨C receive well-deserved praise. Our results, however, suggest that convincing sceptics about the merits of international students also requires appealing to self-interest. By showing how international students help finance home students, for example.

by LSE professor Stephen Machin and Richard Murphy at The University of Texas at Austin revealed that by paying higher fees, international students in effect subsidise certain domestic students.

A recent also highlighted the benefits that international students bring to the UK economy. The findings by the Higher Education Policy Institute and Kaplan International Pathways revealed how international students outstrip their costs roughly tenfold.

Educating international students can even help to advance the UK¡¯s national interests. Antonio Spilimbergo, economist at the International Monetary Fund, how international student exchanges with democratic countries facilitate the spread of democracy abroad.

Likewise, my previous research with Daniel Krcmaric of Northwestern University in the US how developing world leaders who are educated in the West are more likely to pursue democratic reforms in their home countries. In the long run, this makes all countries ¨C including the UK ¨C safer and more prosperous.

If international students do have a downside, it¡¯s that too often they leave after graduation. This deprives the economy of valuable skills. Yet this is a problem with , not talented international students.

As Jasmine Whitbread, CEO of London First, a not for profit advocacy group : ¡°With firms struggling to fill skills gaps and vacancies outstripping the people available to fill them, it is economic madness to send these talented youngsters packing as soon as their studies are over.¡±

As someone who teaches at one of the world¡¯s most international universities, I know at first hand the unique benefits of international students. Balancing a global student body with a commitment to the nation isn¡¯t a zero-sum game. UK universities know this, but they need to do better at explaining why.

If, as my research shows, self-interest drives public support for international students, then it¡¯s essential that Britons know the facts. International students offer myriad advantages for the UK ¨C and they should be welcomed with open arms.
