Angel Island is an island on the San Francisco Bay ... For the thousands of immigrants from Asia, especially Chinese and Japanese who came in the 1800s, Angle Island was their first contact with mainland United States.

These immigrants went on to work in the emerging west of the United States, mostly working as laborers, cooks and laundry people.
