My stepdaughter has recently married her undocumented boyfriend. The primary reason for getting married was to help him gain US citizenship. They have a child together and our grandson was just discharged from 4 days in a children’s hospital due to a finger infection. My step-daughter has also been receiving food stamps for some time now. They are asking me to sponsor him by completing an I-864 Affidavit of Support. I have some strong reservations but my wife is pressuring me to comply. Medi-Cal and food stamps are clearly means tested assistance. However; my wife claims I don’t need to worry about being held responsible for our grandchild’s medical bills because the father’s name is not on the Medi-Cal paperwork. But what happens if the government puts 2 and 2 together and discovers his son is a Medi-Cal recipient? The step-daughter concedes she “may” have to give up the food stamps. I love the kids and would help them if I could; but I believe completing the I-864 would make me liable for my grandson’s medical bills as well as being liable for the value of the food stamps my stepdaughter is receiving. We live in the state of California, who is correct; the wife or me?
