I have a quick question on sibling proof of residence. My wife's blood sister is a PR iving here in canada since 2017 . We have claimed 15 pts for sibling relationship. As per cic requirements we have to provide proof of address for her like utility bill etc. She does not have any utility bill on her name. Its actually on her husband's name. However I can provide her salary slip & bank statement mentioning her address. Can u pls guide if it is acceptable by cic?
