This was a surprising and interesting move by President Obama.  For years, Deferred Action was a little used idea - offering a temporary opportunity to stay in the US for some kind of extreme humanitarian reason. There was no form or formal procedure.  It was really a request directly to the local USCIS District Director.  Now that discretionary remedy is being expanded and formalized into one of the largest immigration programs around.  This is not a status, or a visa, but a kind of limbo. It is a discretionary decision by the Department of Homeland Security not to try to remove (deport) someone who does not have a legal right to stay. 

DHS stated that "economic necessity" is required to receive a work card through Deferred Action. One of the three forms involved in the DACA application is an I-765 WS worksheet, which is used to determine whether or not there is economic necessity. We expect, but cannot be sure, that DHS will find that most 15-30 year olds who cannot work and have no assets can show economic necessity.
