is it a problem if someone lived in US before?? how come?? one of my friends lived in us (illegally) but he left the us to his home country 3 or 4 years before landing in Canada. Will it be an issue for him??
Goldline,
It should not be a problem, however in recent years if you have a residency somewhere else it might question your residency in Canada and it could be looked at it from a prospective that your residency in Canada is a temporary it nature. Normally, these kind of questioning ends up with an RQ, or so or even an interview with a CJ to proof ties to Canada.
However, this is just my theory which built on what I have heard and seen so far, and each case will be different. For your friend it should not be a problem (if he does not have any criminal or other issues) as this period of time will not show on his Citizenship eligibility period.
