If you lose your passport or naturalization/citizenship certificate, it is important to report the documents as lost and have them replaced. These documents are essential for travel, employment and identification purposes. The U.S. Department of State is responsible for issuing you a new passport and the U.S. Citizenship and Immigration Service (USCIS) will issue you a replacement citizenship certificate. If you report your passport as lost, it immediately will be invalidated and no longer good to use for travel purposes.
Complete Form DS-64, Statement for Reporting a Lost or Stolen Passport. This form is available from the U.S. Department of State website, passport acceptance facilities, passport agencies, and a blank form is listed below under Resources. Sign and date the form at the bottom of page one.
Submit the DS-64 form to:
U.S. Department of State Passport Services Consular Lost/Stolen Passport Section 1111 19th Street, NW Suite 500 Washington, DC 20036
This will report your passport as lost but will not cause a new passport to be issued to you.

Bring your DS-11 form, DS-64 form, birth certificate, valid photo identification, front and back copy of your photo identification, two 2-inch by 2-inch passport-style photos of yourself, and the $120 passport fee.
