Answer:
In Port and other coastal cities.
Step-by-step explanation:
Most of the inmingrants arrived to United States looking for better opportinites as Europe, generally speaking, was not having its best time. Most of the inmigration was made via ships, therefore many of the inmigrants remained near ports and coastal areas. Cities with large numbers of immigrants on that time were Boston, Philadelphia, and New York, as well as Pittsburgh, Detroit, Chicago, Cleveland, San Francisco, and Los Angeles.
