I was immigrated to Canada on basis Spousal (family class immigration) in 2004. I stayed in Canada for complete three years and then I applied for Citizenship but respected Judge issued me questionnaire which I was not able to answer. Then my second PR Card was issued in 2010 and with that card I came back to Pakistan. With the renewed PR Card, I went to Canada for few days only and after that I have been staying in my home country. My Second PR card expired in 2015 as I was not able to go back due to unavoidable circumstances. I also want to inform you that my 4 children are adults and living in Canada and my wife died in 2009. Please let me know if there's any possibility that I could secure my permanent residency back? What could be the possible procedure to have my pr back?
