How long can I apply for a green card after working in the United States?

If you apply for asylum, you will get a work card in the fourth month after you pass the interview in three months. If you don't pass, you can apply for a work card, and then continue the interview until you pass, and some of them have been delayed for several years. The best case is that if you pass the first interview, you can get a green card in one year, change it into a permanent green card in two years and take the naturalization test in five years. But you can't go back to China until you get the citizenship exam. If you want to go back to China, you will never go back to the United States. The success rate depends on your interview with the immigration officer, which requires a high IQ. If you don't succeed, you will have been in the United States for several years, and you can change your identity through marriage. If you don't change your identity, the interview will still fail, and you will be deported from the United States and will not be allowed to enter the United States for ten years or even life.
