Who needs to be present at family based green card interview?

[shakti]

I am sponsoring my mother's green card. My husband is a joint sponsor (filed i-864A).

Do we both need to be present along with my mother at the permanent residence interview? Or, is it enough if only I go with my mother to the interview.

Who all need to be present at the interview?

[PraetorianXI]

Petitioner and Alien. You and your mom, but you will need the sponsor's financial documents, employment letter, etc.

[yadith]

The petitioner doesn't have to be present; only the applicant; however; if you go, it would help with providing papers that the counsel may ask and your mother may not know. I went with my mother, and I spoke for most of the part; and asnwered all the questions for her and provided all the extra papers; the counsel seemed to like it because I speak English, and it went fast; and my mother got the visa the same day in the afternoon; but now the some embassies are not given the visas right away; sometimes they mail it to you.
