The K-1 Visa did not ask for information about the fathers. It asks if the children live with the beneficiary to which I replied yes. I submitted everything required by the instructions and birth certificates were not listed as a requirement and I only recently found out this information about the fake fathers and it has me very concerned. Last year she told me she didn't list the fathers, so I assumed the father section was left blank because my own daughter here did this on her child's birth certificate. My granddaughter has no father listed on hers, so I assumed this was a possibility. Then a few days ago when I tell her to collect certain information, including birth certificates, in preparation for the interview, she tells me she listed fake names and assures me that she has researched this herself and it will not affect anything because "she has full custody of her children." I told her I am skeptical of that because I'm afraid immigration will not accept that.
