The paper focuses on what is old and what is new in transnationalism by analyzing extraterritorial attempts of the Italian and Mexican governments. During the large southern/ eastern European immigration to the US from 1890 to the 1920s, Italian immigrants reached 24 percent of the immigrant wave. Mexican documented and undocumented immigrants from the 1980s until 2010s made up 30 percent of the immigrant wave almost a century later. Transnational immigrants live in a country in which they do not claim citizenship rights and claim citizenship rights in a country they do not live in. Therefore migration and immigrant policies challenge both sending and receiving states. Foreign governments are limited in the policies and practices that they can enforce. A comparison of state policies from Italy and Mexico challenges the fact that transnationalism is significantly different and new.
