C.   Issuance of Certificate of Citizenship 

In general, USCIS issues a Certificate of Citizenship after an officer approves the person’s application and the person has taken the Oath of Allegiance, if applicable, before a designated USCIS officer. USCIS will not issue a Certificate of Citizenship to a person who has not surrendered his or her Permanent Resident Card (PRC) or Alien Registration Card (ARC) evidencing the person’s lawful permanent residence. If the person established that his or her card was lost or destroyed, USCIS may waive the requirement of surrendering the card.[5] See 8 CFR 341.4. The requirement to surrender the PRC or ARC does not apply to applicants naturalizing under INA 322. 

If USCIS waives the oath requirement for a person, USCIS issues the certificate after approval of his or her application for the certificate. In such cases, USCIS issues the certificate in person or by certified mail to the parent or guardian in cases involving children under 18 years of age, or to the person (or guardian if applicable) in cases involving persons 18 years of age or older.[6] See 8 CFR 341.5. See Part J, Oath of Allegiance, Chapter 3, Oath of Allegiance Modifications and Waivers.
