thanks for prompt reply , there is another scenario which is why I was bit confused, a friend of mine his mom was a landed immigration in 60's and she left Canada within a year. Now her son sponsored her on a visit visa . Which was granted she came in and her torn half page of landing paper was there she went to service Canada and they issued her SIN and after that she applied for status and got it after almost 55 years. So what do you comment on this scenario
