Thanks sis, InshaAllah your husband will join you in Canada soon.
I did not send them any voluntary information and did not involve any MP. Whatever I sent them with the application that was all I sent. Although I did visit my husband twice after four months and every time I stayed there for four months. My husband is a student and so am I. When I recieved the confirmation of my file transfered to ISB, CIC mentioned that do not contact us unless your status changes or you have addition to your family etc if you are under the normal processing time. It was also written that we will contact you if we need additional information from you. That's why I did not involve MP's and did not send them additional information.
I did my application and answered all the questions to the point. One of my friend applied for her husband after two weeks through a lawyer and her husband didn't recieve anything yet not even re-medical. When I sent my application, I said to Allah that I have done my best and now You do whatever is best for both of us.
I don't think the occupation matters, just leave it on Allah and not worry about it all. Have strong faith on Him and InshaAllah you will hear good news soon.
