Form N-470
December 6, 2022
Form N-470, Application to Preserve Residence for Naturalization Purposes was released by USCIS if you are a lawful permanent resident who must leave the U.S. for a period of one year or longer to engage in qualifying employment and you want to preserve your residence to pursue naturalization. In general, you must have been physically present in the U.S. as an LPR for an uninterrupted period of at least one year prior to working outside the country. If you are eligible for naturalization under section 319(b) of the Immigration and Nationality Act because you are married to a U.S. citizen working for certain organizations overseas, you are exempt from establishing the naturalization residency and physical presence requirements and will not need to file Form N-470.
