Final answer:
During the late 19th century, European immigrants to the United States were processed at Ellis Island in New York Harbor, while Asian immigrants were mainly processed at Angel Island in San Francisco Bay.
Step-by-step explanation:
During the late 19th century, immigrants coming from Europe would have been processed at Ellis Island. This small island located in the New York harbor served as the main port of entry for millions of individuals seeking a new life in America. The processing station was operational from 1892 to 1954, with its peak immigration years between 1900 and 1910 when over nine million people arrived.
Ellis Island is well-known for having welcomed European immigrants, who were subjected to health inspections and legal interrogations before they could enter the United States; only about 2 percent were turned away.
Conversely, Angel Island in San Francisco Bay was the counterpart for Asian immigration, mainly Chinese immigrants, from 1910 to 1940. Upon arrival, immigrants endured long detentions and strict interrogations, especially following the Chinese Exclusion Act of 1882. Immigrant life for the Europeans in New York often began among multicultural neighborhoods which provided a comforting slice of their home countries, amidst the vast melting pot of America.
