What's the difference between an American green card and an American citizen?

The difference between a green card and an American citizen is that:

The green card is a permanent residence permit issued by the US government. Green card holders are not American citizens and do not enjoy the rights of American citizens. Naturally, they don't have to bear the obligations of American citizens. Why is there a green card? Apart from people who depend on their relatives, it is mainly because the United States wants to attract world elites to work in its own country. A green card is equivalent to a permit for long-term residence and work, indicating that the United States needs such talents. Therefore, with a green card, you can of course apply to become an American citizen, but it does not mean loyalty to the United States.

Simply put, there is still a clear line between a green card and a citizen. People who have a green card have left the United States for more than a year, and if they return to the United States, they are likely to be taken back, because leaving for too long means that they have no plans to stay for a long time. As for American citizens, they can leave as long as they want, and there is no time limit. In other words, the green card can be taken back by the US government at any time, and the citizenship is different.

Another difference between a green card and a citizen lies in rights and obligations. According to the US immigration law and related laws, people with green cards must pay taxes when they work in the United States, but if they want to maintain their green card status after leaving the United States or returning to their own countries (regions), they must pay taxes to the US government. On the contrary, if you don't pay taxes, you will lose your green card qualification.
