Neogeofl, I'm not immigration expert but since you're ethnic Italian, I guess you can get Italian citizenship, check with immigration there. But I'd advise against going there, sure many people fancy the life style but the bottom line is, can you make a living there? When I lived in Canada there're many Italian immigrants, they had to come to North America since jobs, resources are scarce and competition for those are fierce.
There're many things we have here people take for granted, ie: cheap food, housing, and jobs (even if some aren't ideal). In Europe (worse in many other parts of worlds), those are well protected for their own citizens and people compete for those fiercely, you wonder why so many people try to risk their lives to come to US. This reminds me of a few years ago in Argentina during the economic fallouts, many Argentines of Italian decents lined up at Italian Embassy wanting to move to Italy, do you know what they ended up doing? Either washing dishes or doing other menial jobs.
Another factor, although it may seem minor, is the cost of living, even if you do secure a job there, check how much your take home income can buy in Italy, you'll be shocked. Ultimately, if you don't speak perfect Italian, you'll always be treated like second class citizen, this is a concrete fact. If you really like the lifestyle there, why not work in US only for 9 months, and spend the rest of the year living in Italy, it might change your mind very shortly about moving there.
