It's an executive order which is not a Law. Bambam knew he had NO chance of getting the "Dream Act" through congress and didn't even try. Just wrote an executive order and acted like it was a law; which it is not and never will be. Can be rescinded with the stroke of a pen the same way it was "passed". I wouldn't put 2 cents on any of his executive orders be in place a year from now.

They can and have been reversed by succeeding presidents.
