What impact did the first American immigration have on the United States?

If Columbus hadn't discovered the new continent, America, and broken the long-term relative isolation between America and other continents, the culture and lifestyle of America wouldn't have changed so much, which promoted the birth of the United States to some extent.

Under the British colonial oppression, immigrants from all over the world began to unite, the American nation began to form, and the national consciousness of early immigrants gradually awakened, which promoted the enhancement of American independence consciousness, further accelerated the rapid development of capitalist economy after the War of Independence, and provided favorable conditions for American economic development.

In addition, early immigrants brought a lot of labor, advanced science and technology, production experience, advanced capitalist production technology, civilized lifestyle, modern institutional norms and so on to the United States, which promoted the development of American economy and culture. Without early immigrants to explore the American continent, the United States would still live a primitive life under the control of Indians. The arrival of early immigrants provided a human and theoretical basis for the establishment and development of the United States. So early immigrants can be said to be the founders of America. They brought democracy and freedom to the United States, and their contribution to the United States is immeasurable.
