I want to ask the third type of immigrants to the United States to give their passports to the United States. What will be the next step and how long will it take?

Wait for the next step, hehe! Did you immigrate with your family? It may depend on your mother's family's income and work, but also on your own working ability and bank deposit. The American government doesn't want to raise people for nothing. But I heard that foreign countries are easy to handle, and it should be easier to have your mother to provide you with a guarantee. Relax and wait. If you have any questions, you can go to the website of the American Embassy. The embassies in Guangdong and Beijing have written in great detail.
