Can I keep my green card?

Since you obtained the green card as your wife's beneficiary, your legal status depends upon her having had legal status at the time that she filed for you. Unfortunately your reporting your wife could involve your green card. If your daughter is born in the US, she is a citizen by birth and is allowed to remain even if you and your wife ultimately have to leave the US.
