Among them, there are still many Chinese. Some people come for the education. Some come here to avoid political persecution. Besides, from 1990 to 1996, about 85 percents of the immigrants from Hong Kong came to the United States because of the uncertainty after the return of Hong Kong to China. These are the main reasons why Chinese come to this country in the modern days.
Some Chinese immigrants come to the United States to be with their family members.
Because the United States is generally a better place to live than China. People usually choose to come to the United States instead of going back to China. There are opportunities everywhere in the United States. In the United States, if you are willing to work, you usually have enough to live on a good life. Therefore, people with knowledge want to come to the United States because there is no opportunity for them in China.
