Do I need some extra documents to avoid any problems/questions in naturalization process? I had 2 separate trips to Japan in past 5 years. Each of trip was 179 days and 180 days (less than 6 months, but very close). For each time, I moved out my apartment for saving rent, and used my friend's address as my mailing address while I was out of US. I kept my bank accounts, but changed their addresses to the one in Japan to receive some financial reports. I kept my driver's license and filed tax returns with my friend's address of San Frnacisco. I had my re-entry permit for making sure that I can come back to US during both trips. I think I did not break any rules, but still not sure if I am safe about these long trips. Do I need to parepare any supporting documents?
Any advice is appreciated.
