Form DS-3053
Form DS-3053 is a U.S. Department of State statement of consent used when a legal parent or guardian whose consent is required cannot appear with a child for a U.S. passport application.
It is a passport-consent form. It is not a general permission letter for an airline, cruise, school trip, or border crossing. If Passport Services asks for DS-3053, a travel-consent letter does not substitute for that form.
Current State Department instructions, including whether an electronically notarized consent may be submitted as a printed copy, control the execution path. Notarization, if used, does not decide whether a passport is issued.
