The immigration debate is becoming increasingly technical, with universities arguing for different OECD measures and inevitably, the need for more and better data. But this isn’t a technical or even an economic debate. Like many other issues it is about politics and the concerns of voters – informed and uninformed. We find ourselves in a corner because the Conservatives (and not their coalition partners the Lib Dems) pledged to bring down immigration from the hundreds to the tens of thousands in their last election manifesto.

UKBA’s student immigration proposals have no intellectual coherence
by Debbie McVitty February 2, 2011The immigration minister Damian Green gave a speech yesterday to the think tank Reform explaining the proposals set out by the UK Border Agency in its consultation on student visas.
The legal firm Pennington’s, who are experts in immigration law, suggested this week that the consultation itself could be illegal.
The Conservatives pledged to lower net migration to the ‘tens of thousands’ in their General Election manifesto. Since taking office they have realized that through a quirk of data processing that counts student in net migration figures even though very few international students take up permanent residence in the UK, enacting this pledge would require drastic cuts to international student numbers.
