What is the main difference between a green card in the United States and a suspended deportation?

The American permanent resident card, also known as the green card, is an identity document used to prove that foreigners have the status of permanent residents in the United States. "Getting a green card" refers to the immigration process of becoming a permanent resident. The legal permanent residency of green card holders is an official immigration benefit, including conditional permission to stay in the United States and get a job. The holder must maintain his permanent resident status, and if he no longer meets certain conditions required by the status, the holder may lose his status.

According to American citizenship and immigration law, green card holders are foreigners who have neither American citizenship nor American citizenship. However, in the United States, they basically enjoy the same treatment as their nationals, but they have 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 home country passport to enter 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 a visa at the American embassy or consulate. If you leave the United States for more than one year, you must apply for a re-entry visa (I-327) before leaving the country. Re-entry visa, as an effective immigrant 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 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: "According to the immigration law, the privilege of" permanently residing in the United States as an immigrant "has been granted, and this status has not changed." In other words, if the green card owner changes his identity, his permanent residency will be immediately eliminated. Therefore, if a permanent resident inadvertently uses an inconsistent identity (for example, filing tax returns as a non-resident), his permanent resident status will be terminated at the same time. In addition, according to the case law of the United States Court of Appeals for the Federal Circuit, giving up (such as settling in another country) can automatically lose permanent resident status without first filling out the form or passing the judgment of the immigration court.
