Immigration to Italy, distinguish the difference between green card, permanent residence and naturalization.

Hello, for example, if you apply for immigration to the United States, you have all the conditions and have been approved by the US Immigration Service. At this time, you will have permanent residency in the United States, or permanent residency in the United States. With this identity, you can live, work and enjoy local social welfare in the United States. But you are still from China, not from the United States, and your nationality is still China. So you have no right to vote and stand for election in America.

You can apply for an American green card if you have permanent residency in the United States. A green card is actually a card that proves that you have permanent residency in the United States. Because it is green, it is commonly known as green card.

With permanent residency in the United States and a green card, you can apply for American citizenship if you want after a few years, when you meet the requirements of American citizenship. Once you become an American citizen, you are no longer from China, because China does not recognize dual citizenship. Moreover, your green card will be revoked because you already have American citizenship, not permanent residency. Italy is the same.
