Why did the Red Scare lead Americans to demand limits on immigration?

The Red Scare intensified fears of communism and radical political movements in the United States, leading many Americans to associate Immigration with potential subversive influences. As immigrants were often perceived as outsiders who might bring radical ideas, there was a growing demand for restrictions to protect national security and preserve American values. This climate of suspicion also fueled xenophobia, prompting calls for policies that would limit the influx of immigrants from countries seen as politically unstable or ideologically threatening. Consequently, the Red Scare contributed to a broader push for restrictive immigration laws during the early 20th century.
