Visit the U.S. Department of State website. Print out Form DS-11 and complete it in black ink. You may, alternately, fill out DS-11 online before printing it or obtain a form at a passport acceptance facility. Do not sign the form -- you have to do so while in the presence of an acceptance agent.
Gather the materials required for a passport application. This includes evidence of U.S. citizenship, a valid ID, photocopies of your ID, two identical photographs and Form DS-11.
Visit a passport agency. The U.S. Department of State website includes an acceptance facility search page that you can use to find a location.
Present your DS-11 form and supporting materials to an acceptance agent. Pay the application and execution fees. As of 2011, the application fee is $140; the execution fee is $25.
Sign the DS-11 form when the acceptance agent prompts you. Give the agent your passport photos. Within roughly four to six weeks, you will receive a passport.
