Expert advicr would be most welcomed on this case. I landed in Canada in April 2017 as permanent resident with my wife and 2 children. I have had to return to my home country in October 2010 as my mother was seriously ill. My wife and children stayed in Canada as the children already joined school and we did not want to interupt their education. I stayed mostly with my mother but vidited my family once yearly specially during the festive season. Unfortunately i could not complete the residency obligations at the time my PR Card expired in May 2015. I was about to submit my application for approval of my PR card when i was told that i should be in Canada to apply for renewal. So i arrived in Canada and submitted my application for renewal. Unfortunately i had to rushed back to my home country end July 2015 as my mother was very ill. She eventually passed away in August 2015. After that very sad event I could not return to Canada as my PR Card was no longer valid. I received a notice to appear for an interview in September 2016 and send a letter to CIC stating the reasons why I could not attend. CIC replied and requested that I applied for a PRTD and that my file would be kept open at CIC until April 2017. I applied for the PRTD in December 2016 and by April 2017 did not receive my PRTD. So another letter was sent to CIC requesting to keep my file open. PRTD was received in June 2017 and valid till December 2017. CIC was sent a copy of the PRTD and i requested that a interview be scheduled. So i have my interview next week and would be most grateful for any help, like the type of questions I can expect, hint on the answer that i should give and what coukd be the most probable taking into consideration what i have explained above. I forgot to tell that my wife and children are now Canadian Citizens now. Thanks for your help.
