I thought they were technically required to have submitted their final decisions by March 1st? If that's not the case, then my mistake! That's partly why I was wondering. I know I'm probably grasping for straws here, and the USC office will probably confirm that. I'm really just asking!
The reason why I'm looking into it is because it could have a really big impact on my life I wasn't willing to defer a two-year commitment to my job for a year for anything except a Fulbright, and the firm couldn't wait for another 3-4 weeks, so I told them I would start working this June. That being said, if I called them back on Monday and said I had received the award, then they would probably still be able to defer the position. Hope that clarifies my position!
