I was born, raised and live in Canada and currently hold a dual Citizenship with Italy and Canada. My parents are both Italian, born in Italy and immgrated to Canada. Before this, My Grandfarther Immigrated to the U.S in 1918 and served in world war I and was legionar and worked in the use for 10 years, and collected a u.s penssion. Non of his siblings ever tried to apply for U.S citenship. Me being a grand son to my late Grandfarther who was a u.s citenship, does this grant me the option to become a u.s citenship ??? Just like to know what are my options. Any suggestions be greatly appreciated.. thank you.
