顾客见证

I'm so excited that my I-140 got approved within such a short time! I do think the North America Immigration Law Group did a great job. They are so patient to answer lots of my questions. The recommendation letters and petition letter are well prepared. That saved lots of my time! I will definitely recommend to my friends, as well as other people who prepare to apply for green card!

- X. L., Postdoctoral Fellow

A real pleasure to work with Chen Immigration. I'm very satisfied with the process and, of course, with the result!
It was a persistent, systematic everyday job of their team for several months, tons of e-mails, all replied professionally. No need for a single phone call! No nerves, no hash, no mess, just persistent professional work that resulted in my approval.
Yes they ask for many supporting documents and evidence but the result is a very strong case approved without any RFE. That's extremely important to save time and nerves.

I highly appreciate the support and professionalism of Chen Immigration Law firm. Although it took me a long time to gather all my documents but attorneys from WeGreened.com were never late in replying to any of my concerns. They were extremely meticulous in analyzing my documents and made sure all my supporting exhibits were appropriate. In only 30-days my EB2/NIW was approved and I'm sure it was due to their experience handling of my case. I'll certainly recommend others to consider hiring Chen Immigration Law Assoc. for any kind of immigration purposes. One of my friends is already in touch with them after hearing my success story. I sincerely appreciate their time and effort in preparing my case.

- A. R., Postdoctoral Scholar

We just wanted to thank Chen Immigration for their help during this process. They were absolutely amazing. They responded to all our questions with such detail and were thorough in their examination of all our supporting documentation. They were quick with their responses and always stuck to the timeline. They provided us amazing templates for all out letters of recommendation and overall were exceptional. Highly competent and would strongly recommend to anybody looking for immigration assistance.

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

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
