My father already has a green card in Australia. I want to immigrate to Australia. What should I do? Can we not go through an intermediary?

I agree to the first floor, but I tell you that your father is applying for you now. He only has a green card, so it will be relatively difficult to pass the exam. If your father has nationality, he can also apply for it for you! Australia is different from the United States. When you are over age and your father has nationality, you can also apply. I'm not sure about the specific approval and waiting time. Your father had better ask an Australian immigration lawyer or a local immigration official, which is more accurate. After all, the immigration law has been revised!
