父母綠卡填寫864表和864a表的問題

我和我姐姐都各自有單獨家庭，我是主申請人，我姐姐作為聯合申請人，現在填寫864表和864a表遇到幾個問題，還請老師解答，謝謝！

1. 我填寫的864表中的house hold member和sponsor都應該是誰？

2.我姐姐填寫的864a表中的house hold member 和 sponsor都應該是誰？

3. 864a表中 Part 5項, Intending Immigrant Number 1 和 Intending Immigrant Number 2 分別填寫了我父親和母親的信息。那麽在

I, THE SPONSOR,in consideration of the household member's promise to support the following intending immigrant(s) and to be jointly and severally liable for any obligations I incur under the affidavit of support, promise to complete and file an affidavit of support on behalf of the following named intending immigrant(s). (Indicate Number)這一項中，Indicate Number應該填2對嗎？

 

謝謝解答！
