I started working with Chen Immigration Law group on summer 2018 for my I-140 NIW application. At first, I was a little bit confused and worried because I did not know how the process works but the super well-organized system that Chen group has made it much more easier for me. I found this group very responsible and accurate in details of each steps in my case prepration. I am so thrilled and happy to work with the Chen Immigration group and strongly encourage others to do the same thing, because I guess applying for a green card is a huge step in everyone's life and I believe working with a professional immigration group with a strong background, who knows exactly what should be done for this process, would lead to a successful result.
