How did world war i affect legal immigrants to the US?

World War I significantly impacted legal immigrants to the U.S. by intensifying nativist sentiments and leading to increased scrutiny of foreign nationals. Many immigrants, especially those from enemy nations or perceived to have loyalties elsewhere, faced discrimination, deportations, and restrictions on their civil liberties. As a result, Immigration policies tightened in the post-war years, culminating in the restrictive Immigration Act of 1924, which aimed to limit the influx of immigrants from certain countries.
