Angel Island Immigration Station Icon created for the museum for the immigration station on Angel Island.

A timeline of immigration that gives a sense for the number of people who came to the U.S. in different periods, where they were coming from, in some cases why they were coming, and the U.S. response to the influx. This outline is meant to capture basics in a mostly chronological order and highlighting legislation or noteworthy milestones about immigration policy. It is imperfect.
