this message is not for future EAD. Who knows what will happen in the future, we may not be live. It is for the current EAD.
I mean by current, not the one in your hand now which is C08 category, it is the A05 category that it is in production now based on the asylum grant.
Just to explain more:
When an asylum applicant applies for asylum, the government issues for him an EAD category C08 spending asylum" to enable him to work and a restricted SSN. But when he get an approval, the asylum office applies for new EAD category A05 'granted asylum' on behalf of him because this is his status now. This new EAD will enable this applicant applies for unrestricted SSN.
So, based in your status now, you will receive an approval letter and your stamped I-94 within 1 week.
After that you will receive a new EAD category A05.
Take your new EAD, approval letter, stamped I-94, your old SSN and your ID and go to nearest Social security office to apply for the unrestricted SSN.
