Hello All
I am in process of filling out an I-864 form for my mother-in-law (Beneficiary)
Here is my situration:
My wife filed a petition for her mother (my mother-in law). My wife currently does not work and do not have any income. I will be the sole/primary sponspor
My wife is filling our for I-864 and I will fill out form I-864a as soon as we 're done with wife's form
I have a quesiton regarding my wife's i-864 form
Q#8 on the form states :
(checkbox) I am sponsoring the principal immigrant named in Part 2 above.
(checkbox) Yes or (checkbox) NO (Applicable only in cases with two joint sponsors)
Does she need to say YES or NO.. Again, she is not the sponspor and does not have any income at all. I am so lost. Please help

ALSO does she need to answer question#25 regarding federal tax return. I (husband) filed tax return jointly but she did not have any income
