A London university has been banned from teaching overseas students, leaving more than 2,000 undergraduates potentially facing deportation. London Metropolitan University has had its right to sponsor students from outside the EU revoked, and will no longer be allowed to authorise visas. Ministers have concerns over issues such as whether or not students are working instead of attending courses. A task force has been set up to help students affected by the decision. The UK Border Agency said it had "failed to address serious and systemic failings" identified six months ago. As well as stopping the university, which has 30,000 students in total, from accepting new applications, losing the licence could also affect thousands of existing overseas students at the university. The National Union of Students (NUS) said it could mean more than 2,000 students being deported within 60 days unless they found another sponsor. 'Panic and heartbreak' The university's Highly Trusted Status (HTS) was suspended last month while the UKBA examined alleged failing, preventing it from being allowed to recruit overseas students. Immigration Minister Damian Green said London Metropolitan University had failed in three particular areas: More than a quarter of the students sampled were studying at the university when they had no leave to remain in this country. A "significant proportion" of checked files found "no proper evidence" that the mandatory English levels had been reached. Universities must know that students are turning up for their course and are not using a student visa to enter the country for work, but more than half of the records sampled suggested the university "just didn't know" whether students were turning up for classes or not.More information at BBCNews
