UK Border Agency staff failed to check thousands of tip-offs about overseas students including whether they had actually enrolled on courses, a report said today.
The agency had no targets in place for responding to notifications made using the Sponsor Management System.
As a result, notifications of changes to circumstances of students, details of students failing to enrol or attend classes, or curtailment of sponsorship were not being acted upon.
Over 150,000 notifications had accumulated and were awaiting action, meaning that potentially thousands of students had retained leave to remain when they should not have done so. This was a significant failure.
However, Mr Vine said his findings were "generally positive" and that he was "pleased" that the agency had reviewed the notifications.
I was pleased to note that in May 2012 the agency had reviewed outstanding sponsor notifications and launched an operation to identify and remove people, including students, who had overstayed beyond the term of their visa.
This should be an ongoing priority rather than the subject of a one-off operation by the agency.
