2. Helpful to the illegal aliens involved – not really — since they still face deportation for cause, and face deporation anyways in two years since an administrative order doesn’t bind future presidents (and can be revoked at any time). In fact, it puts them in a bind since by working “officially” they are giving the government a list of candidates for deportation.
