I recently received my ECOPR and am waiting for my PR Card. I haven't seen my mother in 3.5 years, and she is all by herself in her home country. I want her to visit me for a few months. She had a visitor visa before, which had expired, but she had never visited Canada due to health issues. Considering the current visitor visa rejection, I am planning to apply for her supervisa. Can I do it right now, or do I have to wait for the PR card to arrive? What documents should I attach for visa success and also where to buy insurance? Can we buy dummy insurance till the time we get visa decision? Thank you for your advice.
