回複：我的一點意見。。。

Thanks a lot, 假博士.

But My father is my sponsor for my permanent residence, and I am not a permanent resident. Of course he needs to file I-864 for me. Since I have income, so I should file I-864A showing that I have enough income to support myself. That I can confirm.

假博士 is right at no 3. But no 1 and no 2, I am not sure how to do, can anyone else point a correct way to do that?

Thanks a lot.
