Our client was a scientist who had to leave the U.S. because he was not selected in the H-1B lottery. He explored the idea of an O-1A with his potential employer, and we went ahead with the case. We worked intensely with this client and his employer to answer a lengthy Request for Further Evidence (RFE):  we educated both parties as to the requirements of the category and drafted good support letters from helpful authorities.  We then submitted a strategic, specific response to the RFE, and the case was approved less than two weeks after we sent it in.
