I have an unusual situation, I hope I can get some useful advice here. My girlfriend just adopted her sister from Senegal due to family financial difficulty. She would like to bring her sister/daughter to Canada to study. Sponsoring her for permanent residence would take 2 years, which is a long time for a child (she is 15). We would like her to come to Canada as soon as possible so she can adapt to Canada more easily. She is a permanent resident, and I hear that the dependent of a PR can attend school here for free even on a visitor visa. We are concerned however about having to renew a visitor visa every 6 months. We would like to apply for permanent residence for her sister in the long term, but the top priority is to bring her here as quickly as possible. Would we be able to apply for an open study permit?
