Somehow i got Catherine's email address, she is Immigration Program Manager in buffalo. She replied me by saying that my file needs to be sent to CPP-Ottawa for additional background check however she doesn't exactly know why my file is sent to Ottawa again [that's what i assume from his email..again]. Its wierd, its been almost 6 months after they have received medical results and still they didn't have sent files to CPP-Ottawa. I don't know how long that will take, anyone has any idea? do they need to do security check from home country? if they do then it will take ages.. I applied for my security clearance two years ago and i'm still waiting, do they want same security clearance for PR as well?? I am living in Canada for almost four years... the process is not driving me crazy its taking longer than usual..
