I examined the list of Ali Haider for NOC 0213 and noted that only those applicants got ‘acceptance/wait6-12 months' letter whose full docs reached to London VO after June 2010.Whereas all NOC 0213 applicants who received medical request are those whose full docs arrived at VO till June 2010.
I observed the same.... In fact was pretty confused, initially, that why I am being asked for the medicals, whereas rest of my fellow NOC 0213 applicants are either getting refusal letters and waiting letters....
Then realized that my complete docs were received by CHC in end of April 2010.
I strongly recommend that go ahead with your idea, it will defiantly, help to understand the working of LVO.
