When I immigrated to America, my aunt said it was time. How long does it take to leave China by submitting information to the US Immigration Bureau?

If you start doing this now, it will take 1-2 months to prepare the materials and submit them to the immigration office to get the file number. After getting the file number, you need to wait about two and a half years to get a temporary green card. During the waiting period of two and a half years, you can apply for other visas to travel or study in the United States (under the guidance of professional immigration companies)-overseas Chinese in Jiangsu.
