I would like to share my experience. I have been studying and following forums since 2012, when the first time I decided to immigrate. later on due to different problems and circumstances I wasn't able to apply until 2013. I got late with my HOT noc and file was sent back, then in 2014 Alhamdulillah I got through.
what I noticed is, those all applicants who have applied on their own are facing these difficulties.
those who applied through good reputed immigration consultants they don't face these difficulties. yes there can be some % of them which is less than 5% I believe. not that case which u mentioned. now I don't know what it has to do with applying through consultant as CIC website says there is no need to apply through consultants. but the fact remains same at least for Pakistani applicants, those who applied through consultants got visa sooner and smoothly than those who applied on their own.
THERE ARE ONLY FIVE 5 authorized immigration consultants in Pakistan which are recognized by CIC, ICCRC, CAPIC, CBSA, HRSDC, IRPA, CSIC and RCIC.
so people applying through these FIVE 5 only get their cases easily and quickly than those who apply on their own or other remaining fraud and crook consultants.
