Hi all, ive been looking at this forum for a while now found it very useful and thought i should also contribute with my story. 
My wife applied for a settlement visa on june 27th at the Islamabad VAC and im basically in the same situation as all you guys. Its been almost 6 weeks and still same old....
Ive heard that the average time is 6-8 weeks so we should hear something soon inshallah. My wife's friend got her response after 8 weeks, although her visa app was rejected - not sure why. (Didnt want to make anyone nervous  

 ) 
batleykhan - I think the problem is not the waiting, of course we understand that the application will take time because of the sheer volume, its the service - or lack of it - that is the main problem. They never seem to be able to give you a straight answer about when its going to be done. 
Good luck to everyone waiting for a visa, inshallah it all works out for us!
