My husband is from el salvador and has been in the u.s. illegally for 10 years and married 3 yrs legally.?

my husband has been here 10 yrs illegally, weve been married 3 yrs legally and have 3 children together. He is our family's sole supporter. He is from el salavdor. We would pay for the papers to get him legal, but unfortunatlry we do not have money. Is their anything wee can do fast without him having to go back to his country? anything will help. thank you and god bless you
