Why were immigrants deported in the early 1900?

In the early 1900s, immigrants were often deported due to concerns about public health, economic competition, and national security. Many were labeled as "undesirable" based on their country of origin, political beliefs, or perceived inability to assimilate into American society. The Immigration Act of 1924 further restricted immigration and intensified deportation efforts, reflecting nativist sentiments and fears of radicalism during that era. Economic downturns, such as the Great Depression, also contributed to increased deportations as jobs became scarce.
