He has to stop USCIS from taking any more applications from illegal aliens for DACA.
Every day that goes by with no action 40-50 more illegal aliens are being given work papers and permission to stay.
Even if they don’t rescind the papers already given out they have to stop issuing new ones right away.
It is my understanding that the issuing of papers stopped when Obama lost (again) in court. I hope this is not going on.
