Need advice for sponser docs for sister's visitor visa

[sid_immi]

My elder sister wants to visit USA with her minor son. My younger sister and her husband are sponsoring them. So, which documents she will need from my younger sister? does she need any docs from me? Her visa agent asked for my, my spouse's and my kid's all immigration docs including copy of social security cards and all other docs which needed only from sponsor. I am confuse beacuse I am not sponsoring her. Pl. advice, does she really need any docs from me and my family if i am not the sponsor.


Thanks for you help and advice.

Those agents don't know what they are talking about.
