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.
