We had our IR1 interview a week ago and we brought our joint sponsor's 1-864 with us incase my husband's US job offer letter wasn't sufficient financial proof. Because our joint sponsor filed taxes with his wife, we also brought an 1-864a with us that she filled out. The lady looking through our documents didn't see the I-864a and said that we needed our joint sponsors W2's or the I-864a.
I think it's better to be over prepared for whatever they might look for, rather than risk delaying getting the visa.
viol8tor, my husband's Irish job is also continuing here, but he also went from a full time employee to a consultant role with a set retainer fee. We didn't include that financial info in our own Affidavit of Support as he hadn't the details of it finalised, but if we had we would most certainly have brought it with it - and the joint sponsor info too, then just let the CO decide.
Mand got a reaction from sumitlesia in Is I-864A required if 864 co-sponsor filed taxes jointly?
