1. Your husbands birth certificate and your sister-in-laws birth certificate (to prove the relationship)
2. Sister-in-laws Canadian address proof (recent utility bill or bank / credit card statement) confirming that the person lives in Canada and
3. PR card copy
4. COPR signed by the immigration officer upon landing
are sufficient to claim the 15 points.
Don’t need to wait for Medical Card / SIN etc. as these are secondary documents that are not required and would just waste your time if it’s taking longer to get these. It’s also additional and unwanted documents for the VO to go through.
I hope this information helps.
Thanks
