NEED HELP STARTING SEARCH

[tomatopie2012]

Hello everyone,
I would like to see if I qualify, as a US citizen, to get an italian passport. I know my grandfather or my father needed to have been an italian citizen. My grandfather came from Italy. I don't know if he became a US citizen. From Ellis Island records, I know the ship he came over on, the year, etc. My father's birth records are not showing up in the town in the US I thought he was born in. He could even have been born in Italy. I don't know. How do get started on finding naturalization forms, etc.?
Thank you!
