Open your passport to the signature page. The signature page is the second page in your passport right next to the page with your picture and personal information. The signature page has a statement from the Secretary of State that requests a foreign government to allow you to enter their country. The statement is in English and repeated in French. At the bottom of the page is the line for you to sign your name.
Use a blue or black ink felt-tip, roller ball or calligraphy pen, according to New Citizen.us. Do not use a ballpoint pen.
Sign your full name name in the same way that you signed your passport application, and how you would sign any check or credit card. For instance if you normally sign important documents with your middle initial and not the full name spelled out, sign your passport in the same way. In case of any fraud, it is important that your signature matches up with other documents you have signed. If you have a child that is to small to write his name, sign his name for him and put mother or father in parenthesis next to it.
