I'm glad that the BBC has picked up on this.
As a teacher of English as a foreign language in the Ukraine I know quite a few students who would and will be affected by this if they change the law. In addition it would also impact the TEFL profession in England and cause a reduction in income. It seams so counter intuitive to reduce the number of students who come into the country and benefit our economy just because some may stay beyond their visa's [and they will probably continue to do so anyway].
[I know I said I wouldn't do any political blogs but this crosses over with TEFL so I don't think it counts!]
