My uncle runs a company in Palau (a small continent controlled by the United States) and intends to take my account there. Then I asked our teacher a few days ago and said it was not very good. Yes

There is no such thing as an account. In America, you only need the address, that is, the registered driver's license. If citizens vote for you according to their constituency, that's it. Why is there such a statement as hukou?

Question 2:

Have you asked your teacher? If he were an American, they would never have this experience in their lives. Ask them? All I know is that if you ask an American this kind of question, they won't answer you directly. They will tell you where to look up relevant information, and enthusiastic people will help you check it. Generally speaking, you have to wait in line when you go to the immigration office to ask questions. Security check is slow. You might as well consult a lawyer. The average lawyer may not meet the lawyer himself for the first time, but most of your questions can be answered simply. Teachers who like to preach are only mainland teachers, and the information they don't know won't easily lead you astray. What on earth did he say to you? A little curious.

Question 3:

How did your uncle help you get a green card? Your uncle's company hired you? This may help you apply for a work green card. Visiting relatives, basically immediate family members, it is difficult for your parents to adopt you to your uncle? The chances of getting a green card are slim, but it is possible. You'd better find a lawyer or call the local immigration hotline directly.

Question 4:

If it's just a work green card, that's fine. In fact, it is not easy to apply, because you have an immigrant tendency. If you tell the immigration officer at the beginning, you may be refused a visa. If you are visiting relatives, getting married will be more troublesome.
