Married after filing AOS for brother and sister on behalf of parents

[Frooty]

My mother (PR) filed for my sibling in 2010 May. I (USC) filed Affidavit of support on behalf of her in 2010 itself. During then and interview on 9th october 2012, I have gotten married so I assume my household number has changed?

Do i need to refile I-864 since it has been more than a year?
Do i need to inform change in number of household? This is tricky because if i add my husband, i will go over the poverty limit.

I am really confused!

NVC has not asked for any more stuff with the interview checklist.

Thanks.

You don't need to submit new I-864 unless they ask for it.
