so sorry to hear this.i will advise that you try to raise a CSE together with both birth certificates and plead that the case be reopened.you can write a detailed explanation also stating that both your names were stated in each other's application.were you sent an ADR before the refusal?

@All,i had included my sibling marriage certificate and my birth certificate to show relationship.I had stated on the LOE that sibling marriage certificate was used to show relationship as our father's name was written on both certificates.do you think this will suffice?i had submitted since January.I need your counsel please.

CoCoLav:


Can you post a picture of the refusal letter without any personal identifiers? We can only assume that its because of the NPC issue but seeing the letter will help shed more light.

topeolu1:
Birth certificates or NPC attestation of birth? Depending on your age, the birth certificate may not be an acceptable proof. Attestation of birth is what NPC advised IRCC on for those born prior the decree setting up NPC. I've read about it somewhere on a rejection sent to someone.

This may be one of the snag.

This is a bummer. Birth certificates are the main documents required to prove sibling relationships.

1. When did you get your ITA? And when did your sibling become a PR?
2. Did you submit your sibling's PR card, utility bills or bank statement, bio-data page of sibling's passport?
3. Did your sibling mention you in his/her PR application and vice versa?

Topsmamen:


Wow! So sorry about this. What documents did you submit to prove relationship with your sibling?
