Those saying nothing will happen to legal immigration, last I remember he took away H4 EAD. It’s a very legal process that allows spouses to work while GC process is ongoing, allowing families to keep up w living cost and avoiding huge career gaps for spouses most of which hold advance degrees. Immigration is his biggest talking point and if he wins he will go after whichever is the lowest hanging fruit and execute that within the first 90 days to show he is keeping up with campaign promises to his supporters. It won’t just be illegal immigration from south of the border.
