請各路俠客及過來人幫忙回答麵試信同來的I-864表。

麵試定在6月11日。我是EB1B, 　帶丈夫同時申請４８５。８６４表隨信寄來，讓我糊塗。以下幾個問題請幫忙。１　Part1-1, a, or b, or d, 我覺得哪個都不適合我。２Part3-8, Yes or No. 3 Part 4-19, I know I am not a citizen, not a permanent resident, what does U.S. national mean? Part 21, My daughter was born here, should I count on her?
最關鍵的問題，Am I consider to be a sponser, both for me and my hu*****and?
My hu*****and holds H4 visa, can not work. But we joint file taxes. How much is his total income?
Thank you very much.
