WeGreened has been a pleasure to work with. They were so thorough with everything. With their very knowledgeable and able support and timely help in every respect I could finally get my I-140 approved in EB-1A category.- R. C., Senior Development Scientist
I would therefore highly recommend them to all who wants to file a permanent residency.
I would like to thank the Chen Immigration team for getting my I-140 (EB-1B) approved with no RFE. I choose premium processing and the case was approved in 13 days. The team is very professional and helpful in every step on your way to the approval. I had many questions from time to time during the preparation process and they were answered in a timely manner. I have also retained them for I-485 and hope that it will also be approved in a timely manner.- A. K.
I'm very happy with all the work and advice Chen Immigration Team have put into my NIW application. The responses were always timely, the letters drafted were polite, well-structured and timely. When I got my RFE, I was worried, but with the help of the attorneys working with me, the answer to the RFE lead to approval.- M, Postpoc
Not only do the members of the team work extremely hard and with highest professionalism, they also show that they believe in their clients, are able to emphasize all the achievements better than I ever could, and they genuinely care.
Thank you so very much!
I cannot be happier with everything you've done for me!
It was a privilege to work with Chen immigration attorneys during my NIW I-140 application. They were really professional and kept the deadlines depicted by the client-attorney agreement. They will answer your questions within a day with the maximum clarity. I would definitely recommend them to anyone looking to apply for a NIW green card. Thanks once again and keep up the good work.- I. S., Research Scientist
I'd like to thank Chen Immigration and attorneys for the great job they did on my I-140 application for NIW. They put together a compelling petition letter with appropriate exhibitions which resulted in my I-140 approval only in 72 days at Nebraska Service Center (the average wait time at this center is more than 10 months now). The team at this firm are experts and experienced. They meticulously prepare all the required documents and effectively communicate with the client. They deliver on time & with the highest quality. I have recommended them to my friends who would like to apply for NIW or EB1A. Chen group knows what they are doing and they are the best, go with them!- H. C., Postdoctoral Scholar
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.- S. A., Postdoctoral Researcher
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.
