Your husband can petition for you kids as long as they are under 21 and your marriage took place before the kids turned 18. If the kids entered the USA legally they do not have to leave the country, they can apply for a Green Card here. If they entered illegally, they will have to leave the country and return back with a visa after all the paper work is filed and a date is given to them for a visa interview in their home country. They will not need a waiver if they leave the country before they turn 18.
