I am a member of the US army and a naturalized US citizen. We filed for my spouse I-130/ I-485 concurrently. He had entered the country in 2001 with C1 visa and overstayed. I was not aware that he was ineligible to adjust status in the US. We received the denial for I-485 (I-130 approved). Is there anything we can do at this point? Is there a waiver avilable to apply? We have a 18 months old US citizen daughter. Any information is appreciated.
