Sponsor documents ... visa status

[silpau]

Hi,

I have my visa interview on 5th nov.

My brother-in-law is sponsoring my trip.
Both my sister and he are US citizens.

Will my sisters US unexpired passport(ALL pages) and BIL US unexpired passport(just front and back not ALL pages) sufficient as their legal status proof.

I have read https://www.immihelp.com/proof-of-le...a/#citizenship and i wasnt sure if all the items a-e are required .

For US citizen ship proof is a xerox copy of their green card required..
Totally confused..

Thanks

They do not require a copy of the green card for US Citizens, only for residents.
