I'm a single parent and US citizen and want to apply for my baby's passport. However, the father of my child is not in our lives ever since the baby was born and has not been responsible for any of the baby's needs. The nationality of the baby father's is Mexican with only their visa. I have not filed anything in court since he does not want to have any of the baby's responsibility. I know this does not guarantee to get my baby a passport, but is it possible? I have the hospital bills which my parents took responsibility in paying, would that help too? Forgot to mention my baby is a US Citizen as well.
If you are the only parent taking care of the child, you should apply for a court order granting you sole custody of the child. If you have this, you can apply for the child's passport without needing anything from the father.
If you are unwilling or unable to do this, you will need to submit a Form DS-5525 "Statement of Exigent/Special Family Circumstances" explaining why the father is not reachable. But I would recommend you go for the court order instead, it will simplify many other things as well.
