The Chen Immigration Law group was recommended to me by a fellow postdoc at a networking event. He claimed that if they say that my credentials are good enough to file a case for a green card then it is almost certain success. He was absolutely right.- P. F., Post-doctoral Scientist
After evaluating my credentials we decided to apply under the EB2-NIW category. Overall, it was a pleasure working with them. All my questions were answered promptly and to the point. Although the communication was only through emails, it was very effective. They made very clear to me what documents are necessary and how to obtain them and they drafted amazing reference letters and the I-140 petition letter. The price was very reasonable (the best I could find) and they always keep their timeline.
I am really grateful for their service and I highly recommend them. Thank you so much!
