USCIS Update: Change of Filing Location for Form N-400
WASHINGTON - U.S. Citizenship and Immigration Services (USCIS) today announced revised addresses for applicants filing an Application for Naturalization (Form N-400) at USCIS Lockbox facilities in Phoenix and Dallas. This filing address change takes effect immediately.
Applicants who previously filed their applications at the Lewisville Post Office (P.O.) box will now file their applications at a P.O. Box in Dallas. See address below. In addition, the table below includes a change to the USCIS Phoenix Lockbox address. Starting immediately, applicants filing Form N-400 at the USCIS Dallas or Phoenix Lockbox must submit the application and all supporting documents and fees to the following addresses, based on where they live:
The U.S. Postal Service will immediately forward mail from the Lewisville Post Office to the new post office in Dallas until December 31, 2009. After that date, the Postal Service will forward the mail through normal channels, which will likely delay receipt at the Dallas Lockbox facility.
Applicants filing a Form N-400 under military provisions (Section 328 or 329), should file their application at the Nebraska Service Center, PO Box 87426, Lincoln, NE 68501-7426, regardless of where the applicant lives. This includes current military spouses regardless of geographic location or jurisdiction.
If you are filing a Form N-400 at USCIS Lockbox facilities, you may elect to receive an email and/or text message notifying you that your application has been accepted. You must complete an E-Notification of Application/Petition Acceptance (Form G-1145), and attach it to the first page of your application.
The N-400 form instructions have been updated to reflect the new filing locations.
