The University sector is a fantastic industry in the country. It produces exceptional graduates, it's one of our best exports and has led to the regeneration of many towns / cities.
The recent drive to lower net migration (which includes international students) will only shoot ourselves in the foot and weaken an industry which has helped the economy. International students are a vital part of university funding and are essentially a cash cow: they come to the UK, spend a load of money and then leave. They are predominantly young people so their burden on national services (e.g. public education, the NHS) are very minimal.
