UK's foreign students concerns

The UK's Immigration Minister, Damian Green, is raising concern about the number of foreign students being allowed into Britain.



He says the practice is unsustainable.



Green has warned that new rules are needed to ensure that every student arriving in the country is what he calls a legitimate student doing a legitimate course.



His comments follow government research suggesting that one in five migrants from outside the European Union who came to Britain to study are still in the country five years after they arrived.
