Please note that U.S. passports cannot be amended to change information that appears on the biodata page of your passport. If you have legally changed your name, you will need to apply for a new passport under your new name.
If your passport was issued less than a year ago, please make a passport appointment. Bring your current U.S. passport, a completed but unsigned passport application form DS-5504, an original marriage certificate or court order showing the legal change of name, and one new photo meeting the specified requirements. There is no fee for this service.
