N-400 Naturalization - Continue to File with USCIS Service Center Having Jurisdiction over Your Place of Residence
On June 5, 2008, the USCIS announced that it has centralized the initial processing of all Form N-400 (Application for Naturalization) at its National Benefits Center in Missouri.
However, this change will not change where an applicant files his or her N-400 application.
Applicants will continue to file their N-400 along with all supporting documents and fees with the USCIS Service Center having jurisdiction over their place of residence
Also, applicants will also continue to report to a local field office for the naturalization interview and naturalization test.
So, don’t send an N-400 to the National Benefits Center because if you do, the USCIS will simply return it to you.
Residents of Pennsylvania, New Jersey and Delaware will continue to send N-400 applications to the Vermont Service Center.
