I already contacted the lawyer at this moment to start to process the EAD application. Although I think I can apply it myself, I'm worried that I will make some careless mistakes because I'm still in a shock about this issue.
I guess that I'm not lucky, and my case is very special. To be safe, I will apply a new EAD card. The only concern from my lawyer is that INS might ask why I need a new card while I still have a valid card.
Thank you very much for your quick response.
