The USCIS examiner will do three things at the naturalization examination:

Go over the application in detail with the applicant, checking for accuracy and completeness;

Test the applicant’s ability to use English; and

Test the applicant’s knowledge of U.S. government and history.

If no decision is made within 120 days of the completion of the interview, the applicant may file a case in the U.S. District Court, which may either decide the issue itself or instruct the agency to do so.

If the application is denied, the applicant may request an administrative hearing before a different USCIS officer, who will be designated by the district director. The request for a hearing must be made within 30 days of denial. If a hearing results in a final administrative denial, the applicant may seek review by a federal district court.
