There are no official guidelines for the content and format of a consent letter, but they usually include: the name of the child the names and contact information of parents or guardians the name and relationship of the person who is accompanying the child information on where the child is travelling and the duration of the trip

If the child is traveling with only one of their custodial parents, they must have a letter of consent, preferably in English and notarized, from the other parent or signed by both parents. The letter should say "I acknowledge that my son/daughter is traveling outside the country with [the name of the adult] with my permission."
