Why did the US want to limit the entrance of Europeans and Asians?

Answer 1

The U.S. sought to limit the entrance of Europeans and Asians primarily due to concerns about economic competition, social integration, and national security. The fear of job competition and the belief that immigrants could dilute American culture fueled nativist sentiments. Additionally, specific laws, such as the Chinese Exclusion Act of 1882, reflected racial prejudices and aimed to restrict entry from certain Asian countries. These factors combined to create a legislative environment that sought to manage and limit Immigration from these groups.
