Hello,
I am now beginning this process and believe I am eligible. I'd really like to hear someone else's opinion also.
Situation: My great Grandparents came to the US from Calabria, Rocca Imperiale in 1907. My grandfather was born in 1917. My GGF naturalized in 1955.
I believe I am eligible as my GF was Italian by his father and US by birth. My GGF naturalized after my GF was born, and even after my mother was born.
My path is GGF>GF>mother>me.
