question about my parents green card interview

I sponser my parents to get green card. We received the interview notice, it shows we also need to bring my siblings' birth certificates.I do not think we have time to do it. My siblings are all in China and do not want get green card. Do we have to prepare their birth certificates for my parents application?

Thank you very much.
