I-864a household member relationship to the sponsor

[A.M.E 1]

Hi guys,

I have a simple question, kind of a ridiculous one

My USC husband's stepfather is going to be our joint sponsor, but he's going to combine his income with his wife's, so she's filling out the I-864A

On form I-864A question 8(relationship to the sponsor), she needs to check one of the boxes.

Of course in this case it means relationship to the joint sponsor, that is, her spouse, and NOT relationship to the petitioner(my husband). Right? Just to make sure.

Thanks in advance

Anyone?
