The Immigration Quota Acts of 1924 were a radical departure from previous US immigration policies. These laws were designed to severely limit immigration from Southern and Eastern Europe, especially from Italy, Poland, and Russia.
The most important effect of the quota system was to drastically reduce immigration from Southern and Eastern Europe. In the decade before the national origins quota system was enacted in 1924, an average of 757,645 people per year immigrated to the US. In the decade following the enactment of the national-origins quota system, the average number of legal immigrants per year dropped by 82 percent to 138,450.
Indian Citizenship Act
The Indian Citizenship Act of 1924 granted US citizenship to Native Americans. This act overturned a 1887 Supreme Court ruling that had declared Native Americans living on reservations as "domestic dependents" but not US citizens.
Soldier Bonus
Congress approved the World War Adjusted Compensation Act in 1924, which provided a bonus to approximately 4 million World War I veterans that could be collected immediately as cash, or 20 years later with 25% interest.
