So you're taking the family on a trip to Canada and wonder whether children need a passport. The short answer is yes. All citizens, including children, in the United States, Canada and Bermuda must have a passport to enter or re-enter the United States.
Minors Under 16 Years Old
Children under 16 must apply in person for a passport. Both parents or guardians must be present at the time of application to sign parental consent.
Minors Ages 16 to 17
Children ages 16 to 17 must apply in person for a passport. Parental consent must be provided on the application or by notarized statement. A parent or guardian is not required to be present unless the minor does not have a photo ID.
All minors must submit a certified copy of their birth certificate or naturalization documents that prove citizenship and parental relationship. A photo ID of the minor or the parent or guardian must be presented.
Minor applicants must submit two identical, color 2-by-2-inch passport photos. In the case of newborns and infants, supportive devices are prohibited in the photos.
Cost and Processing
A child's passport costs $60, as of October 2009, plus a $25 processing fee. The time to process is three to four weeks. Separate checks are payable to the U.S. Department of State and the processing facility.
