I have asylum case pending in NY with finger print done and waiting for interview letter. In meanwhile after 150 time period applied for work permit and got approved. I got approval letter in which it specify the time period of work authorized i.e. one year . But however I was expecting to get actual card with picture on it. I need to apply SSN now I am wondering do I need to wait actual card to arrive before applying SSN or that approval letter is my EAD and I will not get any actual card picture on it.
