Yes, indeed I did. For those 3 I uploaded my and my sister's birth certificates and also our father's family booklet with further details to prove my relationship with her, and I uploaded her Citizenship and passport in the proof of citizenship slot. For proof of residency, I have her T4 2019 and her credit card last month's statement ( the utility bills are in her husband's name and they own the house, so no lease contract) ..should I ask also for her driving license or this is enough?When I say *other sibling documents* , I dont literally mean your other siblings you have - they are irrelevant for proof of relationship. I was talking other things such as proof of residence and proof of relationship etc. Its just that they ask for 3 types of proof for the sibling so I'm just saying you should ensure you upload it in the correct section on the application
Thank you so much for your support
