What was the major goal of the U.S. immigration laws of 1920?

The major goal of the U.S. Immigration laws of the 1920s, particularly the Immigration Act of 1924, was to severely restrict immigration, especially from Southern and Eastern Europe, as well as from Asia. This legislation aimed to preserve the racial and ethnic composition of the United States by implementing quotas based on national origins. The laws reflected the nativist sentiments of the time, promoting the idea of American homogeneity and limiting the influx of immigrants deemed "undesirable." Ultimately, these laws sought to control the demographic landscape of the country in alignment with the interests of the prevailing social and political ideologies.
