My boyfriend is being detained by immigration. He is illegal and I'm a us citizaen. We have a 4 month old baby and want to get married. What can we do to keep him from being deported? He was entered into the US when he was a child and has lived here ever since. His mother is the principal beneficiary of an I-130 filed by her brother in the year 1996 and the priority of the petition became current September 2011. Can this help him stay in the US or getting married to him will he is being detained?
