How likely would that be to lead to a better outcome than both the slaver or the slave being deported? Any solution that grants immigration status to people (who are often, as the woman in OP's story, not even literate) "just" on the basis of them having been enslaved is probably not politically tenable in the US. The most you can hope for is some sizeable amount of damages to be paid, and depending on the legal framework of the source country they subsequently get expelled to, I wouldn't be at all surprised if the slaver could just reclaim the money once they are back.
