Success Story: EB1A Approved Despite RFE! Dual NIW + EB1A Victory for Indian Medical Director via Premium Processing

“It has been a pleasure working with Chen on my EB1A NIW journey. I heard about Chen years ago and hence had the confidence to go with them. I liked their meticulous attitude in preparing the case draft and collecting evidence. Chen has a ton of experience with EB1 and NIW categories. Chen has also been prompt in responding to my queries. I was told the officer who had issued my RFE had only a 30% approval rate. I was nervous due to the recent significant drop in the EB1A approval rate. However, Chen was a great help throughout the process, and I am satisfied with her service. I wish them all the best and endorse her for physicians willing to file an EB1A NIW petition.”
