There is no such thing as the "DREAM" Act - that never passed Congress. What you are referring to is DACA (Deferred Action For Childhood Arrivals) which I understand you finally obtained at the beginning of the year and I assume you are now wondering how to renew it once it expires in early 2016 for you and if to renew your DACA based employment authorization card you'll need to got through the whole process of DACA application again. The answer to that now is that no one knows yet for sure, as the government has not yet announced the renewal/extension procedure. Stay turned.
Kindly be advised that the answer above is only general in nature cannot be construed as legal advice, given that not enough facts are known. It is your responsibility to retain a lawyer to analyze the facts specific to your particular situation in order to give you specific advice. Specific answers will require cognizance of all pertinent facts about your case. Any answers offered on Avvo are of a general nature only, and are not meant to create an attorney-client relationship.
As others have stated, there is no Dream Act but you are very likely referring to DACA (Deferred Action for Childhood Arrivals). The government has not yet announced what the process for renewing DACA status will be, but it is expected that the announcement will come very soon. When the announcement is made the process, requirements, and fees will be known. So keep on the lookout for information regarding renewal of DACA status.
