I'm just here to let you know that is POSSIBLE, I got the protected person status in Canada last year and last september I applied for my mom's visitor visa to Canada. Every forum, every page, any kind of opinion will say is impossible. Well, I'm here to tell you that today my mom was approved to visit me in Canada and spend time together. I'm so happy for this, it has been 4 years since the last time I hug her and the best part is that she can come to visit me any time she wants. Keep it up guys, worst battles are the ones we don't fight. Try try try.
