I don't think that there is a generation problem with you claiming your Italian citizenship. It depends on the information that you have and the information that you will have to supply to the Italian Consulate General in New York. You will need to contact the Italian Consulate General in New York (Manhattan) and also I recommend that you visit their website and read up on what they are requiring at this time for citizenship.
You will have to have all the pertinent records )orignals with seals and appostiles from the governing offices in the state where your ancestors lived in the U.S.
for all parties involved...
parents and yourself.
proving that you are the decendant of the person or persons who were Italian citizens.
Where in Italy were they born? I can help with telling you where to write for copies of the birth records from the Comune in the town of their birth.
I obtained my dual citizenship two years ago and am so glad I did... I now live in Italy.
Thats very generous of you Mr.,Raffa Can I refer everybody to you who is seeking italian citizenship for assistance. I am assuming you are a voilunteer and are not charging anyone for this assistance. Please let me know. Please furnish your e-mail address. Peter
