please Help on I-864

[ydsaad]

My wife a US citizen wants to apply for he mom GC (I-130). My wife does not work and we file tax jointly.

With I-864 (Affidavit of Support Under Section 213A of the Act) does she need to file I-864A(Contract Between Sponsor and Household Member) between me and her. Or I-864 is enough by itself

Thanks
