Timeline of American immigration history

The US is a nation of immigrants. So they must have been welcoming all immigrants. But it is not the case. Probably through out its history, people who had to fight with labor markets with these immigrants hated them all the time, while employers who could benefit from eager immigrants welcomed them.
