Why did new immagration stir opposition from the americans?

New Immigration stirred opposition among Americans due to fears of cultural and economic threats. Many native-born citizens believed that immigrants would take jobs, drive down wages, and strain public resources. Additionally, there were concerns about cultural differences and the perceived inability of new immigrants to assimilate into American society. This led to a rise in nativism and anti-immigrant sentiments during various periods in U.S. history.
