Do I qualify through my Italian GM?

Appreciate any info on whether I may still qualify for Italian citizenship and what the process may look like for me now with the new rules.

Here are some details:

• GF born 1892 Messina

• Came to U.S. 1911

• Listed as “Alien” on 1917 military registration

• Naturalized in 1919 (listed as “unmarried”)

• GM born 1900 Messina

• Came to U.S. 1912

• Married GF 1920

• My father born 1935/Died 1973

My parents/GP never returned to live in Italy.

My mother told me my GM never went through any formal naturalization. So she was automatically naturalized when she married my GF? So is this a “1948” case?

I am also an “adoptee.” My mother (non-Italian) remarried (a non-Italian) when I was a child. I was formally adopted by my stepfather and my surname was changed.

I have obtained my original birth certificate (non certified - stamped “not valid for ID”) with my Italian birth name, as well as current certified birth certificate.

I also have a certified copy of my Adoption Decree which lists my Italian birth name, biological and stepfather’s names, and biological father’s birth/death date.

So with my GM being born in Italy and marrying a U.S. citizen in 1920, and my adoption background, do you think I will qualify with the new Decree rules?

I think I have a “1948” case with an adoption issue? So I still have to pursue with a judicial case, or is this now an administrative/consular case?

And if I am able to eventually obtain citizenship, would my children (early 20’s) then be able to apply for the 2 year expedited residency requirement for citizenship?

Thanks for any guidance!
