It's always wise to have plenty of documentation when traveling with children in today's world. For changing details on entry requirements for children traveling abroad, keep up to date by going to the U.S. Department of State website: http://travel.state.gov. To prevent international child abduction, E.U. governments have initiated procedures at entry and exit points. These often (but not always) include requiring documentary evidence of relationship and permission for the child's travel from the parent or legal guardian not present. Having such documentation on hand, even if not required, facilitates entries and exits. All children must have their own passport. To obtain a passport, the child must be present -- that is, in person -- at the center issuing the passport. Both parents must be present as well. If not, then a notarized statement from the parents is required. Any questions parents or guardians might have can be answered by calling the National Passport Information Center at tel. 877/487-2778 Monday to Friday 8am to 8pm Eastern Standard Time.
