If she is there and so are the kids, you probably have some kind of path to citizenship or at least residency, even if it is not immediate. Being the parent / guardian of a citizen is something to start with in most places, at least. But only if they are actually there.
If there are no kids involved and you are no longer married, I would guess that you have nothing to work with.
