Foreign officials and transportation companies are vigilant concerning documentation for children crossing international borders.
Remember, those customs officers as well as other authorities both inside and outside the United States are looking for missing children and may ask questions.
Make sure you carry the proper identification for yourself and any children traveling with you, including any documents that might be required by the authorities of the country you intend to visit and by US authorities on your return to the US with the child.
Generally, persons younger than 18 years of age could be considered children.
Proper identification includes, but is not limited to, a valid passport for the child when traveling outside United States
We strongly recommend that children travelling abroad carry a consent letter proving they have permission to travel from every person with the legal right to make major decisions on their behalf, if that person is not accompanying the children on the trip. For example, children travelling alone, with groups or with only one custodial parent should travel with a consent letter.
In addition, we recommend:
It is advisable to have all documents, including a consent letter, legalized for other countries (Apostille or consulate legalization) and have certified translation so that the validity of these documents will not be questioned.
