Legal Question in Immigration Law in Ohio

He cannot adjust status in the U.S. based on the information you've provided. He's ineligible due to his entrance without inspection. You can file for a visa petition for him, he can depart the country and attempt to obtain an immigrant visa at his home country's consulate. However, he's accrued more than one year of unlawful presence and therefore is barred from returning for ten years. That ten years can be waived if you are successful in showing it would be an extreme hardship on you if he cannot return. We never indicate the "chances it will work" as we simply don't have enough information on you, your children, or your life which would constitute the basis for the waiver.
