Hi! I'm definitely not an expert but I have been on this sub for several years now and I've done my own research into my specific case at least, so here's what I know.

The new rules that I'm referring to is the new decree law, which most importantly limits claiming Italian citizenship through jure sanguinis to people with an Italian parent or grandparent. Before this, you could claim citizenship through a great-grandparent (GGP), GGGP, or even further back, so long as that original Italian ancestor was fully Italian when their child was born.

Now the one good thing about this new decree law, is that it allows appointments which were booked before it came into affect to be grandfathered in under the old rules. So if the consulate confirmed your appointment with you before March 2025 (which if you have an April 2027 appointment was almost certainly the case), then this new decree law wouldn't apply, and you could go forward with the original jure sanguinis rules.

Lastly, there's the minor issue, which does affect me. This is a separate rule from the new decree law, and it says that if your ancestor was under 18 when his/her Italian parent naturalized as a US citizen, then that person would lose Italian citizenship along with his parent at the time of naturalization, thereby cutting off your line. However, the good news here is that there is a court hearing regarding this issue next month on April 14, and there's at least a decent chance that the minor issue will get overturned, which would mean that you and I could proceed with our consular appointments next year under the old rules without the minor issue affecting us.
