Which of the following was a provision of the Chinese Exclusion Act that affected Chinese immigrants who were already in the United States?

The Chinese Exclusion Act barred Chinese immigrants from becoming U.S. citizens through naturalization. It also restricted the entry of many Chinese immigrants, but it did not require those already in the United States to return to China or prohibit them from forming Chinatowns. So the provision affecting Chinese immigrants already in the country was the citizenship ban.
