In fiscal 2022,
2.1 million encounters by border patrol, with 1.3 million of the 2.1 million, turned away and sent back to their home countries.
800,000 were allowed in to pursue asylum with court dates pending, and about half of those going through the immigration court process for asylum seekers, get denied and deported/returned to their homeland.
So a good estimate would be about 1.7 million of the 2.1 encountered by border patrol in 2022, were rejected.....an estimated 400k, were kept or will be kept once all immigration judges make their rulings as asylum seekers.
It's bad, but more for all the money it is costing to defend the border, and send these asylum seekers back home, and all the non profit resources and time on them spent etc, many of whom will not be allowed to stay in the end....
We really do need immigration reform, where both sides can offer amendments and debate..... It's been avoided for too long!
