On the issue of American immigrant visa

I think your second aunt may have applied for immigration for you.

The first step for ordinary immigrants is to get an American green card. After a few years of green card, you can choose whether to apply for American citizenship.

If you get a green card, you can live freely in the United States, but you must stay in the United States for more than half a year, otherwise the immigration office is eligible to cancel your green card.

If the green card is approved, the US Immigration Bureau will give you some proof. In that case, you can go to America with your certificate and passport. If you get a green card, you can go back to China at any time. When you return to China, show your passport to the customs officers in China, and they will usually let you into China. Sometimes when you go to America, they will ask you to provide some legal documents. You can show them your green card. If you go back to the United States, you can also enter the United States Customs without a visa.

Interviews usually only ask some very simple questions, and you can sign back truthfully.
