Starting with some background, my mother has three children, my brother (in New Zealand), I (in Canada: post-graduate work permit) and my sister (she got her study permit approved and planning to come to Canada). My mother does not have a husband and as she doesn't want to be alone, she wants to come to Canada along with her daughter. So far I can read on the website that she can apply for a visitor visa to reunite with an immediate family member for a non-discretionary purpose. I am that immediate family member of her as I am her dependent child, 21 years old. The one thing that I'm not so sure about is that if this qualifies as non-discretionary travel. Please share your advice on this and also if you think she can be eligible for any other program.
