Immigration Changes in the USA refers to the significant shifts in the patterns, policies, and demographics of immigration throughout American history, particularly from the mid-19th century to the early 20th century. These changes were influenced by various factors, including economic opportunities, political unrest in other countries, and evolving attitudes towards immigrants within the United States. Such shifts contributed to sectional conflicts as different regions experienced varying impacts from immigration, leading to tensions between northern and southern states over labor, culture, and social values.
