My story in brief:
1) I was adopted at age 15 and knew who my birth parents were before the adopton.
2) My birth mother was born in the US to Italian parents and, as she was born before her father's naturalization and I was born after 1948, I am eligible to claim Italian citizenship via jure sanguinis. There is not question about this.
3) The Italian government requires that I produce certified copies of all birth, marriage, and death certificates, where applicable: mine, my mother's, my maternal grandfather.
4) I have obtained certified copies of all such certificates -- all but my own original birth record, because that was sealed by the state at the time of my adoption.
5) Needing my own original birth certificate, I just recently managed to get a NJ judge to issue a Court Order unsealing all my birth and adoption records.
6) This Court Order was sent to the State Registrar of NJ and I subsequently ordered a certified copy of my original birth certificate.
7) The State Registrar has now informed me that they cannot give me a certified copy of my original birth certificate, only a copy for informational purposes. Apparently my legal birth certificate is the amended with my adoptive parents' names, which prohibits the state from issuing a certified copy of the original.

Question:
So, given that I cannot get certified copy of my own original birth certificate from NJ without resorting to drastic measures, does anybody know if the Italian authorities would accept, for the purposes of jure sanguinis, the informational copy of my original birth certificate along with the certified copy of amended birth certificate, if I can also supply a copy of my judgment of adoption?
My hope is that all the Italian government really cares about is my true blood line. After all, at the time of adoption I didn't undergo a bone marrow transplant or blood transfusion.
Any other thoughts are much appreciated!
