I've already applied for DACA and currently playing the waiting game but I have a couple of questions regarding the SS# and driver's license. 
  
a.)  I already have a SS card that says "Valid for work only with DHS authorization", if I do get approved for DACA, do I still have to apply for a new SS# or can I continue to use the one I have?  It's not a fake, it is an official one given to me back when I still had legal status. 
  
b.)  I live in AZ, which all of u know does not give out driver's license to people who have been granted DACA.  I have an official AZ driver's license also given to me when I was still in legal status.  It's expiration date is 2046.  If I'm approved for DACA, what will happen to my DL?  Will I be able to continue using it or will AZDOT somehow, if at all, invalidate it? 
  
c.)  How do I add a signature below my posts?  I also want to show the dates of importance regarding my DACA status.
