You can file your N-400 application using your parents' address and explain the situation to the naturalization examiner at the time of interview if asked. But please note that there are jurisdictional lines to immigration field offices. If you are moving to another place which falls within the jurisdiction of another U.S.C.I.S. field office, your case would not be adjudicated and would instead be transferred to the one with jurisdiction over your new location once it becomes known.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
