Thank you for the reply. Her husband is already studying there in Canada on student Visa. and my sister, who is in working in Bangladesh, has a Candian visitor visa for next two years (she visited once already). Now provided she applies as principal applicant, and are asked to send passports, will her hubby's student visa be cancelled and converted ot PR visa? We would like to imagine what would happen to current student visa at that time, to avoid any unpleasant circumstances.
Would you recommend, it would be better if her hubby applies after one years of completion of his study there and that would be easier? (he also has past experince in Bangladesh, in public service).
thank you for your advice.
1. No the study permit would not be canceled, the COPR would be inserted in the passport and your b/law would either "land' at a POE or an Inland CIC (by appt.) after your sister "lands"
2. Their choice.
