Complete form DS-11, which is the passport application form. Do not sign the form until you are instructed by an agent at a Passport Acceptance Facility.
Gather the documents required to apply for a passport: photo identification, proof of citizenship and two passport photos. Acceptable forms of photo ID include a driver's license, state, government or military ID card and naturalization certificates. Acceptable proof of citizenship include a certified copy of your birth certificate, naturalization certificate, report of birth abroad or a certificate of citizenship. Passport photos must be of you against a light background wearing regular clothing (hats, nonprescription glasses and uniforms are not permitted in passport photos unless you belong to a religion in which you are required to wear religious garb every day) or just your face in a 2 by 2 inches photo that does not have less 1 inch or more than 1 3/8 of an inch between your chin and forehead.
Visit the nearest Passport Acceptance Facility. Sign your application when instructed, submit your proof of identity and citizenship and pay the passport application fees. As of 2011 the fee is $135. For an additional $60 have your application expedited and receive your passport two to three weeks after your application is received. Otherwise it will take up to eight weeks to receive your new passport.
