To any one out there who can help, I have a question concerning Naturalization and Social Security. Does someone have to be a citizen of the US in order to receive Social Security? My great grandfather came to the US in the 1890s from ????. On the 1920 census he states he is from Germany, the 1900 and 1910 from Austria. Since he is one of my elusive ancestors, I would like to track him down as to exactly from whence he came. I know he applied for Social Security in 1936. If you must be a citizen in order to receive SS, then he must have declared his intentions to become a citizen after 1920 but before 1936. If all of this is so, then all I have to do is search for his citizenship papers between 1920 and 1936. Thanks in advance, Joyce in MI
