I'm trying to learn more about Argentina's naturalization laws from 1910 to 1914. (The years cover the time my GGF Leonardo RUSSO TIESI and his family lived in Rosario before returning to Chicago.)
Specifically, I'm trying to find out if he would have been there a sufficient amount of time to gain citizenship, had he wanted to do so (an article I read suggested that only about 5% of Italian immigrants became citizens at the time).
If anybody could share some information on this topic with me or point me in the right direction, I'd appreciate the help. (My wife is fluent in Spanish, so sources in that language are helpful as well.)
