I am a physician/researcher and hired Chen immigration team for my EB1A case at the suggestion of a colleague.. With impeccable professionalism, they were very very thorough with each step of the application process, paying attention to minutest details... In the end, I was very impressed with the way they presented my petition.. I have never had to have a conversation ever with any one in the firm throughout the process as they were always prompt in responding through the portal, quite a wonderful feat! I have no reservations in recommending Chen immigration team to anyone working on their EB1 case.. Thank you very much Chen team, y'all have been fabulous!
