Well, knock me over with a feather
SSstb21 came over today to get his Christmas present - he actually brought one for DH! And he said he got his Driver's license 3 weeks ago, and is enrolled in courses at BM's college (free tuition) for the spring. No Green Card yet, so he can't work, but he hopes to soon. BM gave him her old car, though he didn't drive over tonight because she was using it - apparently she got in an accident with her new one. Someone else's fault, of course.
DH made his final CS payment last weekend - guess once the money stops flowing in, BM decides to make him be independent. Better than dumping him on our doorstep, I suppose. And overall, good to hear - let's see if he can actually pull off real college.
