What impact did new waves of immigration have in US during the late Th?

New waves of Immigration in the late 19th and early 20th centuries significantly transformed the United States socially, economically, and culturally. Immigrants from Southern and Eastern Europe, as well as Asia, contributed to the labor force, fueling industrial growth and urbanization. They introduced diverse cultural practices and languages, which enriched American society but also sparked nativist sentiments and tensions over cultural assimilation. Additionally, this influx led to changes in immigration policies, as the government sought to regulate and restrict immigration in response to growing concerns about national identity and social cohesion.
