This photo of a Chinese Business was part of the Immigration Service's investigatory case file of Lew Wa Ho, a sales clerk with the store. As a merchant, he could legally enter the United States under the Chinese Exclusion Act, which restricted most Chinese immigration. He returned to China, married, and came back to the U.S. in 1909. He may have submitted this photo as proof of his occupation.
