Have you already taken the Voluntary Departure order from the Immigration Judge? You might be able to extend proceedings while you allow your husband the opportunity to seek naturalization. Does he have the requisite time?
If you decide to take Voluntary Departure, then you will be subject to the 10 year bar. However, you will be eligible to file a waiver for the unlawful presence under 212a9B of the Immigraiton and Nationality Act.
I recommend that you consult with an immigration lawyer to figure out a long term strategy for your case.
Best of luck.

You should have an Immigration Attorney review your possible unlawful presence bars and waiver needs, your I-130 petition, priority date, and visa availability before appearing before the Judge. Voluntary departure might be your best option in proceedings, but it is best to know if you have relief options before your hearing.
