My 67 year old mother received permanent residence status last year and she needs to meet the 730 day requirement in order to keep her PR status within the next 5 years. However, I am unable to bring her to live with me because I am caring for my mother in law who is diagnosed with Alzheimers disease stage 5 and deteriorating fast. My mother is not ill or anything but I dont have the resources to bring her to live with me as I am already taking care of a my mother in law who needs round the clock care and will probably be this way for a few more years. My mother could come and visit me but for max three months a year which will make it 450 days and not 730. Do you think if I present this as a reason, the immigration authorities will renew her PR card when it is time for renewal after 5 years. In this case, it is me who is preventing her entry and not her.
