BS, you have the situation convoluted. The U.S. Attorney General and legal scholars say DACA is unconstitutional because it made law, which only Congress can do.  You should know that laws can be made and changed by Congress only and that the President is responsible for ensuring that the laws are faithfully executed.  The law says illegal immigrants should be deported, Obama’s DACA says they can stay.  The law says non-residents cannot work in the U.S.  DACA says they can.  Do you see the difference?  The President has wide discretion in allocating resources to implement laws, but he cannot issue Executive Orders that make or change them.  Civics 101.
