affidavit of support

[trd75sf]

My father in law is sponsoring his daughter (my sister in law), and my wife wants to also file an affidavit of support. So my question is, is my father in law the primary and my wife the secondary support or my wife would be another primary because she's filing a different form?

Your father-in-law will be the sponsor, your wife will be the co-sponsor.
