I am GC holder ready to apply for citizenship. I have my permanent residence in Pittsburgh, PA, I own a house there, I receive my mail there and I pay taxes there too. My son and my nephew live in our home, they are students at an university in Pittsburgh, and I'm visiting them on monthly basis. Couple of months ago I got a job in Memphis, TN, and I'm working there now, living in a rented apartment. All my current employment records show my address being in Memphis TN, and I needed to do so because of benefits, such as medical coverage for me and my family. However, my pay check is deposited in my old bank in Pittsburgh. I still have my PA driving license, I did not apply for TN driving license, and I did not register my car in TN-I still have PA license plates on it. I did not notify BCIS of any change of address. Where should I send my N-400 Application for naturalization? To Vermont Service Center(as a resident of Pittsburgh, PA) or to Texas Service Center (as a resident of Memphis, TN)? What kind of documents do I need to show to BCIS to prove my residency? Do I need to notify BCIS of my change of address? Best Regards, JD85767
