question on birth certificate - please help!!

[paccha9999]

Hi Members,
Does my mother have to take only my birth certificate for the visitor visa interview or does she have to also take my brother's and sister's(living in india) birth certificate? Please let me know since her interview is very near and my brother doesnt have birth certificate.

thanks in advance..

Only the sponsor's.

For other siblings, she should take the proof of their legal staus in US, if any of them are in US.
