They must appear in person at a post office or passport office, preferably with both parents. If only one parent is available, he or she must bring a notarized parental consent form signed by the other parent. In addition to the child’s proof of citizenship, parents must bring proof of their own identity and proof of their relationship to the child.
After you appear in person, the application can be sent directly to the Department of State or to an expediting company for faster processing.
