In 1882, Congress passed the Chinese Exclusion Act, which, per the terms of the Angell Treaty, suspended the immigration of Chinese laborers (skilled or unskilled) for a period of 10 years. The Act also required every Chinese person traveling in or out of the country to carry a certificate identifying his or her status as a laborer, scholar, diplomat, or merchant. The 1882 Act was the first in American history to place broad restrictions on immigration.
