On February 11, 2013, USCIS published a revised Form N-470, Application to Preserve Residence for Naturalization Purposes, with an edition date of 1/03/2013. USCIS will accept older editions for 60 days. Beginning April 12, 2013, USCIS will only accept the 1/03/2013 edition.
There is now a single filing address for this form. Customers filing Form N-470 must now mail them to the Dallas Lockbox facility. The new centralized filing location will streamline intake functions, enhancing customer service and improving operational efficiency.
