Please can I get some clarity, I applied for the express entry with my husband who indicated that the has a sibling in Canada, he actually does have a sibling but this sibling has refused to provide the necessary documents at the last possible moment, what can be done?
Try to convince the sibling .. As posted above you will need several documents proving existence of this sibling plus the fact that this sibling actually LIVES in Canada... I doubt trying to convince IRCC with anything different will be much use since it adds 15 points which can make alot of difference
