In my opinion you got it all wrong, let me explain you.
Miniter K said we will have 90,000 immigrants in 2009. this mean we are expecting these much application to be processes. Check the statistics esp from labor department in 2008 the number of people became immigrant were higher than mentioned in press. Plus they also assume that 20-30% people will not move in straight away and give them settlement time of 2 years. So, just chill, am from Pakistan doin my PhD in Canada. I have been to lot of country, when I was applying for my first student visa for UK people were telling me that every there is a quota on number of students from Pakistan and it’s already filled, therefore British embassy is delaying case, and from that day am listening rumours. These types of people are time waster speaking without out looking into authenticity of news.
The delay can be higher number of application, and last month may be you have read number of embassies have decrease their staff in Pakistan due to current situation.
