You have to fill out an IM2A for the child, but not an IM2B. Also, when you write your "letter of intent" as far as your support of Jolene, you MUST include the child - they re-read Phil's letter to make sure he mentioned my two sons in it. As well, the letter from his parents saying we could stay with them until we found our own place mentioned both boys by name, and a letter his best friend wrote to kind of help substantiate the relationship mentioned my boys, as he had met them himself.
Is Jolene receiving child support - is there an order for it? Have blood tests been done? I know that in Florida the father's name is only on the birth certificate in the case of unmarried parents if he (1) appears and signs it himself or (2) a blood test is done to determine paternity by the State in order to get child support payments enforced. In the second instance, the State of Florida sends the DNA results to Vital Statistics and they place the father's name on the certificate. In the case of my oldest - no blood test, no name. In the case of my youngest - blood test done, but not until almost a year later and I had purchased about 10 copies of his birth certificate WITHOUT his father's name on it prior to that. So any birth certificate I request now has it on there, but I used the "original" one to get his passport and his visa.
You're in luck if he's not listed. Otherwise - I wish you luck!!
