OPT 刚批下来。正在等SSN. 如果有offer, 可不可以先工作，同时等SSN?

My situation is kind of different. I got my EAD in October because my hu*****and and I applied for I-485 in July. My status is F-1, and I just graudated last month, so I applied for OPT. Fortunately, USCIS didn't know I applied 485, and approved my OPT application and gave me another EAD.

Now I'm waiting for my SSN. My question is that can I work under OPT status before my SSN card is issued? Thanks.
