The problem is they assess all applications very strictly for Pakistani applicants throughout the year it only become lenient for certain time in year, another major issue is that our applications are processed in Abudhabi who hired majority of their staff from another neighbouring countries who assess our applications more precisely in a fear that if they made any mistake they will lose their job so they do reject Pakistani applicants even on a punctuation mistake and when they are lenient which is very rare they even ignore a big time mistake or misrepresentation but that's only a miracle. If you see and compare the ratio the other neighbouring countries have a very good ratios of approvals the primary reason is that their applications are processed in their own country they don't outsource. So there is a big impact on the out come of your visa applications. Secondly our country people also misuse the visa and violate the immigration rules in return the genuine applicants have to pay the penalty in the shape of high refusals. I wish you all the best for your future applications. Don't lose hope but keep this one thing in your mind that whenever you make another application provide as much documents and evidence as possible, just assume this that your application will be processed someone who doesn't know anything about you and he have very negative thoughts about you and your country, it's your responsibility to give that confidence to that stranger that he should believe you and grant you the visa and make this easier and understandable as much as possible for the visa officer.
