Afridi, I can feel your pain... Update from my side on my brother's case... It will be 2 months on April 6 since he sent his student visa application to CHC-Islamabad. With some source, I had to contact my local MP and she made an inquiry @ CHC-Islamabad... At first, they said that we dont have you in the system, but today she called again and got a response that, those lazy f*cks create a file and put everything in the system after 3 months...
So basically, whatever correspondence you sent to those lazy f*cks, they just sit in their mail room and after 3 months they put it in the system...
