See what documents a child needs to travel to or from the US alone or with a parent or relative. Non-US citizen children traveling to the US.Minor children may be able to travel to another country without either one of their parents. I was preparing documents and someone told me that I might need minor travel consent form since I am not leaving. The intention of this letter is to provide consent for a minor child to travel without the company of both legal parents. There are forms you can download and sign for this. Send them with POAs, insurance cards, and this form. The requesting parent's name must be on the birth certificate.
