According to the American Citizenship and Immigration Law, green card holders are foreigners who have neither American citizenship nor American citizenship. However, it basically enjoys the same treatment as its own nationals in the United States, but it has no right to vote and stand for election.

according to the immigration law of the United States, permanent residents must use a valid immigration visa and a valid passport of their home country when entering the United States, otherwise they are not allowed to enter the country. After having an American green card, as long as you leave the United States for less than one year, the green card itself can be regarded as a valid entry immigrant visa, and you don't need to apply for another visa at the American embassy or consulate. ?

if you leave the United States for more than one year, you must apply for a reentry visa (I-327) before you leave the country. As a valid immigrant visa, the reentry visa is valid for up to two years. Cardholders who have not entered the United States for more than a period of time are likely to be sentenced to lose their permanent residency when they enter the country, because the immigration law requires green card holders to leave the United States only temporarily.

The definition of "permanent residency" in American immigration law is: "The privilege of' permanently residing in the United States as an immigrant' granted by the immigration law, and this status has not changed." ?

It means that if the green card owner changes his identity, his right to permanent residence will be eliminated at random. Therefore, if a permanent resident uses an inconsistent identity (for example, filing tax returns as a non-resident) unintentionally, his permanent resident status will be terminated at the same time.

In addition, according to the case law of the U.S. Court of Appeals for the Federal Circuit, permanent resident status can be automatically lost through abandonment (such as settling in another country), without having to fill out a form or pass the judgment of the immigration court first.
