What are the provisions of American law on immigration? thank you

Judging from the history of a country, no country's immigration law was born earlier than the United States, and no country realized that its country needed excellent immigrants earlier than the United States. Almost since the founding of 1776, relevant laws and regulations on immigration have been promulgated one after another. The three main law enforcement agencies in the United States are the State Council, and the State Council enforces immigration laws through its embassies and consulates around the world. As far as immigration affairs are concerned, its biggest role is visa. According to the regulations, any foreigner who wants to enter the United States, whether immigrant or non-immigrant, must obtain an American visa from a foreign embassy or consulate.

Immigration and Naturalization Service (INS).

The US Immigration and Naturalization Service is the core law enforcement agency of immigration law, which is responsible for handling immigration law and non-immigrant applications, foreigners' entry and exit, border patrol, arrest and expulsion of illegal foreigners, refugee review, and punishment of illegal employment. And the United States Department of Labor.

The purpose of American immigration law is not only to recruit talents from all countries, but also to protect the domestic labor market. Therefore, anyone who wants to apply for permanent residence as a professional immigrant must first prove that he has obtained permanent job opportunities in the United States, thus depriving American workers of job opportunities. The institution that examines this standard is the labor department, and its means of providing proof is the labor certificate. In dealing with immigration affairs, the three institutions restrict, influence and are independent of each other. In a sense, it is the easiest and most difficult to immigrate or enter the United States among all countries in the world. It is easy to say that the United States accepted the first batch of foreign immigrants in the world. This is the hardest thing to say. Rejected by the United States, foreigners waiting outside the door are also the most. Foreigners who are qualified or beneficial to American society may not be able to come to the United States, but foreigners who are not qualified or unfavorable to American society may not be able to settle in the United States. What determines all this is the complicated immigration law, coupled with law enforcement agencies with great discretion.
