I don't know, have you been to the border lately? Things are pretty chaotic down there. The Mexican border towns are filling up with refugees from all over the world, and none of them have any idea of their status vis-a-vis the USA. There was a whole encampment of Ukrainians in TJ a few weeks ago, it suddenly disappeared, no idea where they went. There are loads of Haitians milling around with no money and no resources, in fact some of them are finding jobs and trying to settle down in Mexico. It's obvious that no-one in charge knows what the hell is going on, on either side of la linea. I don't blame "Biden" because the man is obviously senile, but whoever's running the government is doing a seriously terrible job of administering immigration.
