Final answer:
The restrictions on immigration in the late 1800s included quota systems that limited the number of immigrants from certain regions and countries.

Step-by-step explanation:
The restrictions that were placed on immigration during the late 1800s were aimed at limiting the number of immigrants from certain regions and countries, particularly those from Southern and Eastern Europe and Asia. The Immigration Laws of 1921 and 1924 established quota systems that limited the number of immigrants from each country to a percentage of the number already living in the US. The laws favored immigrants from Western Europe, such as Britain, France, and Germany, while restricting immigrants from Southern and Eastern Europe. Additionally, laws like the Chinese Exclusion Act of 1882 specifically targeted Chinese laborers.
