Three of my friends who already got green card in EB1 category with the help of Chen immigration recommended me to contact this firm. They gave me free evaluation and approve and refund policy for my EB1B. I don’t know about other firm but I can say that I had a very good experience with Chen immigration. My attorney guided me on every single step and never got irritated even if asked same question several times. I got the answer of all my questions within 24 hours of time. As they promised, they wrote very strong letter of recommendation and drafted my petition within timeline. I was impressed the way they presented my case in the petition and as a results my case got approved in 7 days. I would strongly recommend Chen immigration to anyone trying to get green card under EB1 category. As I heard from my friends and I also experienced that they are the best with impressive team of attorneys. Thank you so much Chen immigration. It would not have been possible without your help. You are doing really good job. Keep it up !

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.”
