Chapter 5 - Motion to Reopen
An officer must execute a motion to reopen a previously approved naturalization application if:
USCIS receives or identifies disqualifying derogatory information about the applicant after approval of his or her application prior to the administration of the Oath of Allegiance;  or
An applicant fails to appear for at least two ceremonies to take the Oath of Allegiance without good cause. 
USCIS notifies the applicant in writing about the receipt of derogatory information or multiple failures to appear through the motion to reopen. The applicant has 15 days to respond to the motion to reopen and overcome the derogatory information or provide good cause for failing to appear at the Oath ceremony. 
If the applicant overcomes the derogatory information and qualifies for naturalization, the officer denies the motion to reopen and schedules the applicant for the Oath of Allegiance. If the applicant is unable to overcome the derogatory information, the officer grants the motion to reopen and denies the application on its merits. 
USCIS must not schedule an applicant for the administration of the Oath of Allegiance if USCIS receives or identifies disqualifying derogatory information. USCIS must not administer the Oath of Allegiance to the applicant until the matter is resolved favorably.
An applicant who fails to appear for at least two ceremonies to administer the Oath of Allegiance without good cause abandons his or her intent to be naturalized. USCIS considers multiple failures to appear to be equivalent to receipt of derogatory information after the approval of a naturalization application. 
An applicant may request to reopen an administratively closed naturalization application with USCIS by submitting a written request to USCIS within one year of the date his or her application was administratively closed.  The applicant is not required to pay any additional fees. USCIS considers the date of the applicant’s request to reopen an application as the filing date of the naturalization application for purposes of determining eligibility for naturalization.  USCIS sends the applicant a notice approving or denying the motion to reopen.
6. [^] Generally, military applicants may file a motion to reopen at any time. See Part I, Military Members and their Families, Chapter 6, Required Background Checks, Section C, Ways Service Members may Meet Fingerprint Requirement [12 USCIS-PM I.6(C)].

Technical Update - Moving the Adjudicator’s Field Manual Content into the USCIS Policy ManualMay 21, 2020
U.S. Citizenship and Immigration Services (USCIS) is updating and incorporating relevant Adjudicator’s Field Manual (AFM) content into the USCIS Policy Manual. As that process is ongoing, USCIS has moved any remaining AFM content to its corresponding USCIS Policy Manual Part, in PDF format, until relevant AFM content has been properly incorporated into the USCIS Policy Manual. To the extent that a provision in the USCIS Policy Manual conflicts with remaining AFM content or Policy Memoranda, the updated information in the USCIS Policy Manual prevails. To find remaining AFM content, see the crosswalk between the AFM and the Policy Manual.
