Those are the sections of the immigration and nationality act that are applied when someone is being deported for being in the us illegally. Practically speaking, this means that your husband is going to have to overcome these bars if he wants to return to the us legally before they expire (10 years after he leaves the us).
At this point, I highly suggest that you consult with an attorney experienced in waivers. My firm focuses heavily on them and I'm in Houston. Of course it's your choice. The reason is that your husband is going to have to ask for a waiver and waivers are extremely complicated. He's going to have to show how his departure causes you extreme hardship. Sounds simple, but it's far from it. I invite you to visit my site: www.tunitskylaw.com and go to the I-601 page where I have lots of free information. It'll give you an idea of what's ahead.
