USCIS Centralizes Initial Naturalization Application Processing

Change to Increase Efficiency and Improve Customer Service

WASHINGTON – U.S. Citizenship and Immigration Services (USCIS) announced today it has centralized initial processing of all applications for naturalization (Form-400) at its National Benefits Center in Missouri. This change is part of the USCIS initiative to increase the efficiency of case management and improve customer service.

This internal administrative change will not change where applicants file their naturalization applications. Applicants will continue to file their naturalization applications (N-400), including all supporting documents and fees with the USCIS Service Center having jurisdiction over their place of residence (see list below). Applicants will also continue to report to a local field office for the interview and naturalization test.

USCIS will send applicants a notice when the Service Center transfers their application to the National Benefits Center for initial processing. USCIS will also inform the applicant how to contact the National Benefits Center and how to check their local USCIS field office processing times. USCIS will return to the sender any application mailed directly from the applicant to the National Benefits Center.

Applicants should continue to send their N-400 application and supporting documents to the Service Center having jurisdiction over their place of residence, as follows:

California Service Center

Laguna Niguel, CA 92607-1040
