I am a Brazilian Citizen, but I am in the process of obtaining my American Citizenship.

My great-grandmother & great-grandfather were from Italy and they migrated to Brazil around 1900's.

My grandmother was born in Brazil, but he (my geat grandpa) and his wife (my great-grandma) were Italian Citizens at the time of my grandmother's birthday.

My mother was born in 1955 in Brazil.

Am I eligible for the passport/citizenship?

Any help is greatly apreaciated! Also if anyone can help me obtain birth/death/marriage records or point me to the right direction would be awesome!!

Thanks for all your help!!
