How long can relatives get a green card after immigrating to the United States?

After the visa is completed, you must enter the country within 6 months; The green card will be sent to your residence in the United States within 1-3 months after entry; After getting it, there are no rules. You can go back to China at any time. When you return to China, you can use your China passport.

I got a green card in the middle and late of the second month after I arrived in the United States.

I hope my answer can help you. If you have any questions, you can keep asking. This is my own experience.
