N-400 Naturalization Applications and New Direct Filings
On December 23, 2008, the USCIS announced that it is revising the Direct Mail Program for the N-400 Application for Naturalization.
Effective January 22, 2009, all non-military N-400s must be filed with the appropriate Lockbox facilities—although there will be a 30-day transition period during which USCIS Service Centers will continue to forward N-400 applications received at their facilities to the appropriate Lockbox location.
Applicants should continue to file military N-400 cases with the Nebraska Service Center (NSC). In order to assist military spouses, NSC will also accept and process N-400s filed by spouses of military members.
As of January 22, 2009, applicants must submit Form N-400 and related supplements to one of two new USCIS Lockbox facilities for initial processing, depending on where the applicant lives.
