My family (Me, my wife, my son aged 5 and daughter 9 at that time) got PR status in 2005, we stayed there for six months (received our SIN cards), my father in mean time was diagnosed of prostate cancer in Pakistan, I had to come back immediately although I was well settled there in short time, my father couldn't make it and passed away, my mother was left alone and there was no one to take care of her. I had no option but to stay. Now my children aged 20 and 24 insists to go back to Canada, my daughter is a Certified Montessori Teacher, she will be finishing her graduation by fall of 2020, My son is in 3rd semester of bachelors and is a Certified Graphic designer. They under no circumstances want to leave their parents behind, me and my spouse have nothing more precious then better future of our children. Kindly suggest /advice how should I put up my case so that I stand better chances of approval.
