Final answer:
The Chinese Exclusion Act of 1882 barred Chinese immigrants from entering the United States.
Step-by-step explanation:
The Chinese Exclusion Act of 1882 resulted in Chinese immigrants being barred from entering the United States. This was the first significant law in the United States to restrict immigration based on nationality. The act halted Chinese immigration for ten years and prohibited Chinese immigrants who left the United States from re-entering. It wasn't until the act was repealed in 1943 that Chinese immigration to the United States was once again permitted.
