My H4 EAD went to new card is being processed status.After updating my new address, it seems to be in same state and has not gone to next status. But few applications applied in my same time frame has received the EAD card. The only difference is that in my application the address was updated whereas for others its not the case. Is it due to some processing delays due to address change or is it usual to get card delayed? Can any one please help me? WAC is the center.
