Can Chinese mainland nationality also have permanent residency in the United States?

Chinese mainland nationality can also have permanent residency in the United States, as long as you get a green card in the United States.

The official title of green card in the United States is "permanent resident card", also called I-55 1, which records the cardholder's photo, fingerprint, name and other information and can be obtained through application. Applicants usually need to have a permanent job in the United States or their spouses and children settle in the United States. If the application is successful, the green card will be issued to the applicant, and the cardholder needs to update the card on schedule.

With the American green card, you don't need to apply for a visa at the American embassy or consulate. You only need to show your passport and green card to enter and leave the United States freely. In addition to voting rights, you can enjoy the same benefits and treatment as your own citizens in the United States. Green card holders usually need to stay in the United States for a certain period of time each year, and cardholders who have not entered the country for more than two years may have their green cards revoked.
