I am filing an EB1-A petition with a law firm. The law firm says that based on their recent experience, EB1-A cases that have requested Premium Processing (PP) have a lower approval rate and a higher RFE rate.

While the statistic may be true, is there a causation between PP and RFE/denial or is it just that cases created in a rush with PP might simply get more RFE or denial?

Thanks
