8 CFR § 335.10 - Withdrawal of application.
An applicant may request, in writing, that his or her application, filed with USCIS, be withdrawn. If USCIS consents to the withdrawal, the application will be denied without further notice to the applicant and without prejudice to any future application. The withdrawal by the applicant will constitute a waiver of any review pursuant to part 336 of this chapter. If USCIS does not consent to the withdrawal, the application for naturalization shall be adjudicated on its merits.
