Once a person crosses the U.S. border without proper documents, that person becomes illegal. President Obama violated U.S. immigration law with his DACA orders. But the courts have pretty much negated his E.O. Only President Trump's kindness allows DACA to continue with exceptions. If the exceptions are violated, the protected status is broken, and the DECA violator received a free I.C.E. trip back to their homeland or origin.
