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. Use our Child Travel Consent form to prove that a child can travel without their parents or guardians. I was preparing documents and someone told me that I might need minor travel consent form since I am not leaving. Each parent can travel with each child, just like you could domestically. No special permission or documentation is required.
