My grandfather received his naturalization papers from the military camp that he was stationed. I did not have to look for it since my grandmother gave me the papers. However I did have to look up his father's paper you can write to the Immigration and Naturalization Service for records. I am sorry I tried to find where the address was on my paper and did not see it. You will need the place of birth, date of birth,name and location of naturalization which would be the place he was stationed at. I hope this helped you.
