Which site served as the main immigration station in New York for millions of immigrants entering the United States in the late 1800s to early 1900s?

• A. Angel Island
• B. Ellis Island
• C. Castle Garden
• D. New York Harbor

Answer: (B)

Ellis Island became the main federal immigration inspection station in the United States starting in 1892, located in New York Harbor near Liberty Island. It was designed to process and medically inspect millions of European immigrants arriving in New York during the late 19th and early 20th centuries, serving as the principal gateway for entry. Castle Garden in New York had served as an earlier processing site, but it was eventually replaced by Ellis Island as the dominant station. Angel Island was the main entry point on the West Coast, primarily handling Asian immigrants, so it doesn’t fit the New York focus. New York Harbor is the location, not the processing station itself.
