Why is it so difficult to immigrate to America?

The difficulty of American immigration lies in the restriction of immigration policy, and the American immigration bill is also revised from time to time, which leads to immigrants being at a loss. In fact, to ensure the smooth passage of American immigrants, the most important thing is to pay attention to the relevant policies of the US Immigration Service and pay more attention to the development direction of the United States. From the consideration of the American authorities, I very much hope that more investors will invest in the United States. So for American investment immigrants, the relative difficulty will be relaxed. Most American immigration projects are "regional center" projects (commonly known as EB-5 projects), and there are many areas to choose from, such as South Dakota, Pennsylvania, Philadelphia, Mississippi and other investment immigration projects.
