Why did rise in immigration increased in the 1920s?

The rise in Immigration during the 1920s was driven by a combination of factors, including economic opportunities in the United States, particularly in industrial jobs, and the aftermath of World War I, which led many Europeans to seek better lives. Additionally, the U.S. government had relatively open immigration policies in the early part of the decade, attracting a wave of immigrants from Southern and Eastern Europe. However, this surge led to a backlash, resulting in restrictive immigration laws later in the decade, such as the Immigration Act of 1924.
