Dual Italian Citizenship Application • Dual Italian Citizenship Application Italian citizenship law is based on the jus sanguinis principle (citizenship by blood), and anyone with an Italian ancestor can claim Italian citizenship. Under the jus sanguinis principle, anyone of Italian descent can claim his or her citizenship. It will be considered citizenship at birth, and no pledge of allegiance will be required. The process consists in claiming the right of Italian citizenship. One crucial step of the process is the documents procurement. Also, when there are discrepancies in the documents, a One and the Same Court Order is often required by Italian Consulates. https://www.simonebertollini.com/immi... If your grandfather was born in Italy and was an Italian citizen when your parent was born, it's possible to apply for Italian citizenship through grandparents. However, you can only qualify in this way if your parent has not since renounced their right to Italian citizenship. https://blog.lawyersinus.com/dual-ita... • Video
