Although there are no options attached, we can say the following.
The effects of immigration on the American culture's economic life were that it caused the introduction of new elements that were brought by immigrants from different parts of the world such as Europe, Asia, México, Central America, South America.
These new groups of immigrants who arrived in the United States through Ellis Island, New York, or Angel Island, California, brought with them the many customs, traditions, values, belief systems that were an integral part of their communities. Some of these intermingled with the White American culture, and this was not well accepted by true Americans
Nationalist ideas started to circulate throughout America, ideas that fostered and supported the American culture, customs, and traditions, and demanded the government to take action against immigrants.
