Can I get an American green card if I stay in the United States for three years and don't return home?

I graduated from the United States, and now I work in the United States and return to work at the end of the year.

International students in the United States can work in the United States and need to apply for OPT, which is equivalent to an internship period with a term of one year. One year, etc. must not work for more than three months.

If you have no job for three months, you need to go back to China.

The student visa is F- 1 and the work visa is H1B. If the company is willing to fund your work visa, then you can work in the United States for 6 years. H 1B begins to accept applications in April and issues visas in June 10. Draw lots according to a certain proportion to decide whether you can get a visa.

It is difficult to find a job, especially for international students, when the American economy is in recession.

The United States adopts a policy of non-expulsion and will not investigate you, but it is not good for you to live in the United States without proper status. If you really want to stay, of course, you can fake your marriage, volunteer and so on. Once your I20 form expires, it is a black account, and you can continue to stay. Once it is checked, you have to return it, unless you change your identity after looking for a job or continue to apply for further study.

Only you know if this is what you really want.
