Beginning October 30, 2011, USCIS will implement a new process for the
filing of naturalization and citizenship (N) forms to streamline and
enhance the filing process. The new process will allow petitioners to
file N-forms at a secure Lockbox location instead of a local USCIS
office. The change in filing location will streamline the ways that
forms are processed, will accelerate the process by which fees are
collected and deposited, and will improve the consistency of the USCIS
intake process.
Beginning October 30, 2011, individuals should begin filing forms
affected by this change to the correct Lockbox location. All forms
received between October 30 and December 2, 2011, will be forwarded to
the appropriate Lockbox facility for processing. Forms received at local
USCIS offices after December 2 will be returned to the individual with
instructions on how to correctly file the form.
Forms N-336 (Request for a Hearing on a Decision in Naturalization
Proceedings), N-600 (Application for Certification of Citizenship), and
N-600K (Application for Citizenship and Issuance of Certificate Under
Section 322) should be filed at the Phoenix Lockbox facility starting
October 30.
Form N-300 (Application to File Declaration of Intention) should be filed at the Dallas Lockbox facility starting October 30.
