Please let me know does she have right to enter in Canada.She was considered as if She was living in Canada since she was with me( I am Canadian Citizen) In Pakistan during her stay.
I told you already she has the right to enter Canada. She is a PR with a valid PR card and she does meet the residency requirements because she has been staying with you.
I will go with her for this Visit I may return back while she will stay in Canada to fulfill Canadian Citizenship requirement(Does she have to stay for 3 years for Canadian Citizenship) IF SHE STILL HAS RIGHT OF PERMANENT RESIDENCY.
She does have to stay 3 years to apply for Canadian citizenship. The processing time for citizenship takes anywhere from 8 to 18 months in most cases. If she leaves Canada during the processing time, she should have someone reliable check her mail and messages. If she is called to appear for test and later oath, she will need to know about it as soon as possible because they don't let you know that much in advance. She could postpone those dates if they are not convenient but that can be a problem too because she may have to wait a long time to be re-scheduled. Immigration does not let people schedule those dates at their convenience.
