Another naturalization question

[Anonymous]

Hi there,

So my grandmother (nona) was naturalized but my grandfather (nono) said he didnt become naturalized because his father was a US citizen, plus my grandfather fought in WWII for the US military, so that automatically made him a citizen as well.

I am eligible because my mother was still an Italian citizen when she was born (even though she was born in this country - my grandmom had her "fresh off the boat"). So what naturalization papers do I need for this situation. I THINK I need my grandmother naturalization papers and some documentation of when my grandfather became an American citizen.

Does anyone know what docs I need in this situation?

Thanks in advance =)
