On September 15, USCIS announced that it is expanding the Direct Mail program to include Form N-400, the Application for Naturalization. Individuals filing non-military N-400 applications should file their application with the applicable Lockbox. USCIS is implementing a 30-day transition period; during this time, Service Centers will forward N-400 forms received at the incorrect Service Center to the appropriate Lockbox location. Please note that military applicants should continue to file their N-400 applications at the Nebraska Service Center.
Starting October 14, 2008, applicants will be required to file Form N-400 and supplemental N-400 files to one of the following two Lockbox locations:
Residents of Alaska, Arizona, California, Colorado, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, North Dakota, Ohio, Oregon, South Dakota, Utah, Washington, Wisconsin, Wyoming, Territory of Guam and the Northern Mariana Islands:
