It's already been 3 months TPS has been started and the EAD card expiry date is Dec, 2016, which is 18 months from June 24, 2015. Already, 3 months passed and not a sign of TPS info, got EAD, however, it is not valid until TPS is approved.

EAD is provided by USCIS where as TPS approval decision is made by Immigration Judge, hence, two different organizations are involved and they are not coordinating. It's taking too long.
