Why did the United States expel illegal immigrants?

Let's talk about why so many people know it is illegal, but they still have to work hard to immigrate illegally. First of all, they must live in a country with poor political and economic environment. For example, natural disasters will occur in some parts of Africa, which makes it impossible for many people to live there, so many citizens are forced to leave their own countries and find other places to live in peace. But why do so many people go to America and Europe? The reason is very simple, because their social welfare is very good, and the social welfare in Europe is even better than that in the United States, and the social security system is more perfect, so refugees can live a much better life after coming. However, because the country's acceptance of refugees is limited, no more refugees are allowed to enter their country after the acceptance reaches saturation, which leads to many illegal immigrants.

Take the United States as an example After they smuggled into the United States, all children born in the United States can obtain American citizenship according to law because of the landing nationality law in the US Constitution, thus enjoying various obligations and rights of American citizens.

The United States will definitely send these illegal immigrants back when it catches them, but it will cost you money to send them back. How can it be possible to repatriate so many refugees, and the cost is high, so it is better to leave them in the United States, because the United States still needs labor, and they can just meet this. I think that's why they let go when they caught half of it.

It is not easy for everyone. Today, many refugees are still forced to go to other countries. They may have suffered a lot that we can't imagine, but we can only pray for them and thank our increasingly powerful motherland.
