Will there really be fewer and fewer immigrants to the United States in the future? Why?

In fact, there are many people who want to immigrate to the United States. However, because of the current policy, the application time is prolonged, and many people can't afford to wait, because many people immigrate to the United States for the education of their children. Unless the children start applying at a very young age, they will easily be over-aged. I hope the next president can give a better solution to the scheduling problem. The risk factor of American investment immigrants is really high. Many people were driven back to China after their investment failed. It is easy to get a green card in the early stage, but it is difficult to ask for conditions in the end. Many people have taken green cards to live in the United States in the early stage, but they can't offer conditions. Therefore, they hope to return to China with their children after marriage. EB5 immigrants have a deep investment, and only need to invest 500,000 US dollars. There are not many threshold conditions in the early stage, and you will be cheated if you are not careful. So immigration must not be simple and expensive. The most important thing is to choose the right one.
