How to qualify for immigration to the United States?

American permanent resident card American permanent resident card (green card) American permanent resident card, also known as green card, is an identity card used to prove that foreigners have permanent resident status in the United States of America. "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. Green cards were once issued by the US Immigration and Naturalization Service (INS). Later, the bureau was merged into the Citizenship and Immigration Service (BCIS) under the Department of Homeland Security (DHS), and its functions were also replaced by this bureau. Shortly after the merger, BCIS changed its name to Immigration Bureau. Foreigners applying for a green card can apply for two important permits. One is the authorized employment card, a temporary work permit that allows foreigners to find jobs in the United States. The second is the early entry permit, which is a temporary travel document that allows foreigners to return to the United States. The rights granted by these two licenses are independent of any existing status granted to foreigners. For example, a foreigner with an H- 1B visa may have obtained permission to work in the United States. [Edit this paragraph] The official name of the green card is "permanent resident card" (form I-55 1). The name of the "green card" comes from its predecessor, the "alien registration and receiving card" introduced at the end of World War II (form I- 15 1). Form I-55 1 is adopted by 1977, and is printed on various colors of paper except green; But despite this, the name "green card" has been used. June 5438+October 2008 10, the main color of the card was yellow and white, and only the color used for the back text was green. A green card contains the holder's name, photo and other information. In recent decades, with the development of technology, many anti-counterfeiting features have been added to green cards. According to the American Citizenship and Immigration Law, green card holders belong to 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. I-327 you leave the United States for more than one year, you must apply for a re-entry permit before you leave the country. As a valid immigrant visa, the re-entry permit is valid for a maximum of 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. [Edit this paragraph] Legal permanent residents who have lived in the United States as permanent residents for five years (or have been married to American citizens for three years) and meet all the conditions listed by the Immigration Bureau can apply for becoming American citizens. Citizens will have more rights (and obligations) than permanent residents (still regarded as foreigners in this respect). These rights include: the right to vote; The right to stand for election in federal and state elections; Eligibility to bring family members into the United States; And federal government positions. Other citizen benefits include visa-free facilities in some countries in the world. Certain circumstances that lead to the expulsion of permanent residents do not apply to American citizens.
