maybe this will help you feel better
my noc is 4121, take a look at my timeline. and, we had a request for additional docs in november 2010, right after receiving our 2nd aor, sent them in december and still we were not really significantly held up by this. we hope we'll have the visa in our passports this year - it's great to know we've reached the medicals stage
i haven't noticed that people have a negative attitude towards uni profs on this forum, why would they? except mbe people who had a less-than-pleasant experience at uni? as with all occupations, there are people who do their job well and those who don't do it so well. still, i'm surprised...
don't worry, they are processing pre-june applicants, just try to be patient, i know it's hard, but that's all you can do really.
all the best
