Witch statement is true about immagration

During the late 1800's many Americans feared immigration because they thought that immigrants would take jobs from hard working Americans. During this time, you saw the nativist American party pop up (although it quickly dissolved), you have the Chinese Exclusion act (which, as the name implies excludes all Chinese immigration), but you also have people like Jane Addams, who wanted to promote immigration and set up the Hull House, a community centre to help immigrants first arriving.
