顾客见证

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.

Three of my friends who already got green card in EB1 category with the help of Chen immigration recommended me to contact this firm. They gave me free evaluation and approve and refund policy for my EB1B. I don’t know about other firm but I can say that I had a very good experience with Chen immigration. My attorney guided me on every single step and never got irritated even if asked same question several times. I got the answer of all my questions within 24 hours of time. As they promised, they wrote very strong letter of recommendation and drafted my petition within timeline. I was impressed the way they presented my case in the petition and as a results my case got approved in 7 days. I would strongly recommend Chen immigration to anyone trying to get green card under EB1 category. As I heard from my friends and I also experienced that they are the best with impressive team of attorneys. Thank you so much Chen immigration. It would not have been possible without your help. You are doing really good job. Keep it up !
Highly Recommended !!!!

- Dr. S. R., Assistant Professor

I applied for EB-2 trough North America Immigration Law Group. I got the I-140 approval in one month ! I would like to greatly appreciate for their professional jobs. According to my interaction with them in filling out the I-140 application during several months, I found them very trustful and expert. Therefore it is my pleasure to highly recommend this firm to persons who like to apply for EB-2 green card or related ones. In addition, the application fee is cheaper that other immigration attorneys. Thanks a lot

- R. N., Independent Research Scientist

Chen Immigration is by far the most professional and meticulous group I have come across. The entire process, right from the evaluation by Victoria Chen, to the final submission to USCIS is systematic and diligently planned. Each and every question is answered and at no point does one feel helpless. The letters are expertly drafted. Kudos to the team and Ms. Chen.

- S. P., Scientist

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.
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!

- M, Postpoc

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
