Indian banks will have a tie up with local banks in foreign countries even if they do not have their own branches....e.g.ICICI has with LLOYDS...you can do a swift transfer...But I would suggest to carry 1000 GBP at least.Why to waste more rupees in foreign exchange conversion?
Do you want it for short time or for a longer period? I stay very close to heathrow...10 min.drive....if interseted..PM me your phone number...room is vacant from 1st march.
I have seen many students who never apply for NI.. and work fulltime all the time..the logic being that they will not be traced by HO...stupid but works/worked for thousands in past for visa extension as HMRC and HO records are not integrated yet.
Most of these collges have their licenses suspended for not maintaining attendance records properly and fulfilling the student's quota rapidly....these colleges are meeting to issue a response to UKBA...co-ordinated with BAC/ASIC,UKCISA
