Thank you for your message. Your husband has a complicated case. When he failed to appear in Immigration Court, he was likely ordered to be removed in his absence. This means that he will be removed/deported if he is caught by ICE inside the U.S. As the spouse of a US citizen, he is eligible for a permanent visa, but generally the process would require him to return to El Salvador to get the visa. When he leaves the U.S., he will have "self-deported" and will need a waiver of the deportation to return to the U.S. legally.
Depending on his age when he entered, and other factors, he might be able to get his Immigration Court case reopened, but the government would have to agree to it.
I suggest that you contact an experienced immigration attorney to discuss your options.
Good luck,
Mark
