dedworth maybe they've found a few people doing 'unskilled' work becuase they can't find any other work at the mo, but to get a tier 1 visa, you have to be young, and i think you still need a masters degree and have had a good paid job back in your own country or you will not get the points needed to get the visa.
also if they are doing 'unskilled' work, they probably will not get an extension on the visa because you have to have earned £25k a year.
as for labours tier 1 , what have the tories done b4 labour or in the last 6 months
