顧客見證

I had a great experience working with Chen Immigration Law Group. I applied for EB1A premium processing and the case was approved within 2 weeks without any RFE.
I was impressed with the quality of petition letter and the reference letters drafted by their team. Although my field is highly technical, the attorneys seemed highly knowledgeable and were able to present my research in a manner which was easy to understand, impressive and yet not 'over-selling'.
They went over my research/citations meticulously and were able to catch mistakes which honestly I would have missed if I was preparing my own case. They were also very prompt with replying to any questions I had during the process.
In short, I would strongly recommend them to all who want to get through the green card process without stress.

- P. J., Postdoctoral Researcher

I am thankful to Victoria Chen and her immigration team for making this happen. I got my I-140 approved in EB1A category. This group is highly professional and I am very satisfied with the services. The reply to all of my questions were prompt. The team is extremely meticulous with documentation and drafting of letters, especially the petition. I strongly recommend North American Immigration Law group for US immigration!!!!

- P., Neuroradiologist and Research Scientist

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

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

Thank You Chen Immigration and Attorneys for your tremendous effort on helping me approve my NIW EB-2 petition. They are very professional from start to end.
