Hi,
First of all i would like to ask you some questions:- if this greencard interview thru family relative or employment based.
IF its thru Family then you'll need the following:-
1. petioner fill out I-864. where his income must be 125% over poverty line. If your petitioner is not over 125%, then he/she can use assets to prove his income status. or you can have a joint sponsor.
If its thru employment, then your employer will fill it out... you don't have to worry about it.
Let me know if you have any other question
