According to the following passage, The Chinese Exclusion Act of 1882 is significant in American History because of this: In 1882 Congress passed the Chinese Exclusion Act. The act was designed to stop nearly all immigration from China. Although a few lawmakers spoke out against the bill, it was passed overwhelmingly. The Chinese Exclusion Act was the first law ever passed in the United States that excluded immigrants from a specific ethnic group. The Chinese Exclusion Act did allow some Chinese to immigrate – such as teachers, students, merchants, and those related to American citizens. Chinese who sought admission to the United States after 1882 had to go through a rigorous screening process to prove that they qualified for admission. Not until 1943, when the Chinese Exclusion Act was lifted, were Chinese from all backgrounds allowed to immigrate to the United States.
What is that it was the first time the United States did not allow immigrants into the country based on their race?
