I had very pleasant experince working with them and I am highly satisfied with their work.They are very professional and have many experiences on preparing the documents for the immigrant petition. They know about the strength of your case and I receive the I-140 approval notice (NIW) just after 3 months. I also retained them for the I-485 service. I highly recommend your firm to scientists and research scholars. This is one of the best choices in my life.

Words can not describe my level of satisfaction working with folks at WeGreened. They have a rigid systematic approach to submit cases to USCIS (i.e. EB2-NIW in my case).
No hitting around the bush during working with you. Straight forward and logical folks. They throw it into your face when you are wrong, accept it with big heart if they fail. Turn-back time to your questions is within 24 business hours with no doubt at every single step of the progress. Do not doubt for even a single second to choosing them, regardless of your geographical point.

- T. J., Affiliate Faculty

The fact I like most about the Chen Immigration and Attorneys is their communication systems and responses. Throughout the whole application process until approval, I had lots of questions in different phases regarding case file preparation, EAD cards, travel with AP, service request etc. What I needed to do was to leave a message in the case management system and got detailed and satisfactory responses in a timely manner.
Their services ranging from the free evaluation at the first day to case preparation and drafting recommendation and petition letters have exhibited high professionalism and standard. I would suggest anyone to retain them for his/her I140 and I485 case preparation.

- S. A., Postdoctoral Researcher

Thank you to the North American Immigration Law Group/Chen Immigration and Attorneys for their unwavering support and help in helping my secure my I-140 approval under EB1A and also under NIW. Their service was professional and timely. They answered my million and one questions with patience and worked with me on every stage of the process. They helped draft the letters and were open to edits and comments from me. What I also liked was that they were open to receiving suggestions from me to help strengthen my case especially when we were responding to our RFE.
Thank you to this team for working diligently and patiently with me to help build my case and get the EB1A petition approved.
I highly recommend them.
