You only keep the number,the Social Security card will be taken away and a new one issued w/ the same number via mail but 'Valid with DHS authorization'.

I also think it is a good idea that Dreamers approved with an EAD should carry a certified Birth certificate to SSA when applying for their SSN.This is just in case there is an issue with someone having the exact same First AND Last name when first applying and it is likely with a population over 300 million.It also would allow you to have your entire name in the system if you have more than 1 middle name!

The biggest benefit now to all Dreamers who have an ITIN is that they will now have the payments they have made onto their Social Security card and have not worked in vain.
