One of the challenges faced by Chinese immigrants who arrived at Angel Island was that Immigration Officials assumed that Chinese travelers would misrepresent themselves to get into America.

From 1910 to the end of 1940, almost 170,000 Chinese immigrants were processed at Angel Island, California, close to the San Francisco Bay. Chinese people faced racial issues when they arrived in America. They were rejected by the people because they were considered strange people by the way they speak and behave. But the real situation is that American people considered then a threat to their work stability because Chinese people offered very cheap labor for the railroad and mining industry.
