My hon. Friend mentions an important point. I shall deal with that in some depth in a moment.
Within the regulatory regime, the current problems are focused on the inflexibility of the tier 4 visa for undergraduate education. Over and above that and linked to it are the problems associated with the post-study work visa. There is no doubt that many international students who want an undergraduate education want to carry that on at postgraduate level in order to demonstrate the skills that they have acquired in local universities, the local public sector or sometimes local businesses. The majority deterrent to that within the existing visa structure is the high salary threshold, which precludes much postgraduate working in areas where salaries for graduates are lower or in professions where salaries for graduates are lower.
Credibility interviews are the process that the Home Office is using to interview would-be international students in their home countries to establish the credibility of their claims to want higher education in this country. The feedback that I am getting time and again from universities is that that approach appears to be incoherent and inconsistent. Taken together with the change in regulations, it reinforces the perception abroad that Britain is no longer open to business. The fact that the Prime Minister needs to go to these countries and make these statements is a tacit admission that there is a real problem and a gap between the regulatory regime as stated by the Government and the perception of it abroad.
