Yes, a parent or legal guardian can apply for a U.S. passport on behalf of their child. The U.S. Passport Agency requires that both parents or legal guardians are involved in the application process if the child is under the age of sixteen. The application must be submitted in person at a designated passport acceptance facility, such as a post office or public library. It is important to provide the appropriate documentation, which includes proof of the child's U.S. citizenship, such as a birth certificate or a previous passport, and evidence of the parent or guardian's identity.
Additionally, both parents should provide consent, which may require signatures during the application process. If one parent is unavailable, a notarized consent form from that parent may be necessary. It is advisable to visit the Passport Services web page for specific guidelines and requirements, as they may vary depending on individual circumstances. Using the official site can help ensure that you gather all necessary materials before your appointment.
