I am a postdoctoral researcher specialized in the field of Biochemistry. I heard about Chen Immigration Team from MITBBS and had the pleasure to retain them for helping me to prepare I-140 filing for both an EB2-NIW case and an EB1A case. I appreciate that the attorneys provided me with detailed instructions and guidance in every step of the case preparation, and answered my questions posted in the system with patience. Thanks to their expertise knowledge in how to present a case for their customers, I was able to assemble my petition package efficiently. I am very happy to learn recently that my EB1A I-140 (with premium processing) was approved in 8 days (Texas service center). I highly recommend Chen Immigration Team to anyone who are seeking professionals to represent them on immigration case filing.
