What were chinese immigrants occupations between the years 1871 and 1913 and where were they?

After the Civil War, immigrants again began to stream to the United States. Between 1870 and 1900, nearly 12 million immigrants arrived--more foreign-born people than had come to the country in the preceding 70 years. During the 1870s and 1880s, the majority came from Germany, Ireland, and England--the principal source of immigration before the Civil War. Even so, a relatively large group of Chinese immigrated to the United States between the start of the California gold rush in 1849 and 1882, when federal law stopped their immigration.
