North America Immigration Law Group (Chen Immigration Law Associates) is a U.S. immigration law firm dedicated to representing corporations, research institutions, and individuals from all 50 U.S. states regarding I-140 immigration petitions. We specialize in employment-based immigration petition and have a proven record of high success rate for the categories of:

We keep close track of the latest immigration trends and regulations of USCIS (U.S. Citizenship and Immigration Services), decisions of AAO (Administrative Appeal Office) and judicial review opinions. The massive collected material contributes to the winning strategies for our clients' cases.

Approval of each case is the goal of our law firm. The key to our success is how we present supporting evidence and the high-quality petition letters based on systematic knowledge and comprehensive database developed by our firm. To provide the best immigration service, North America Immigration Law Group only hires attorneys with J.D. degrees from top law schools.

We have one hundred percent confidence in our capability to successfully represent our clients, and we are the only U.S. immigration law firm with refund policy on I-140 petitions. This is not an empty guarantee but specifically laid out in the attorney-client contract and is binding on our law firm.

We are pleased to announce that North America Immigration Law Group has so far received over 7,500 EB-1A, EB-1B and EB-2 NIW I-140 approval notices. In 2015 and 2016, the approval rate is 97.9% for cases using our Approval or Refund® (money back guarantee) service and 96.9% for all cases.

Our approval rate is 99.6% for NIW petitions using our "Approval or Refund®" (money back guarantee) service and the overall approval rate for all NIW cases is 99.2%.

In terms of EB1A petitions, the approval rate is 96% for cases entitled to our "Approval or Refund®" (money back guarantee) service and the overall approval rate for all EB1A cases is 94.3%.

As one of the leading U.S. immigration law firms providing the most comprehensive services focusing on EB-1/NIW petitions, we are proud to maintain our high approval rates with a large volume of approved cases.

* The number of EB1B approvals is under-estimated because we calculated our approval rates based on the approval notices we received. Some EB-1B petitioning employers did not submit a G-28 so only the employers received the approval notices.

** One denied case was not originally filed by our firm. We took the case after an RFE (Request for Evidence) was issued and the case was denied after the RFE response.

*** Among 125 EB-1A denials, 71 were processed in NSC (Nebraska Service Center) and 54 were processed in TSC (Texas Service Center). The majority of the EB-1A denials processed in NSC were issued by officers who requested thousands of citations for EB-1A approval.

In 2015-2016, our approval rate for O1A I-129 cases is 100%.

Note: These statistics are based on the final adjudication received in the specified year. Some of the cases were approved after appeal, motions, or re-filing.

  • Process Engineer

    First I would like to thank Chen group for successfully petitioning my I-140 NIW case. I came to know and choose Chen group (WeGreened.com) through recommendations from some of my friends who got their I-140 NIW working with them. Overall my I-140 NIW petition is a good but long experience. It took me 14 and half months due to Matter of Dhanasa and its consequence of my stressful RFE. Chen group has worked meticulously and strategically to push it through and finally convinced the USCIS officer. They are experienced, professional, and greatly committed to timelines. I notice more than one time Ms Chen and Mr Holmes spent after-office hours and even weekends working on my RFE to make sure we met the tight deadline. I also like their approve-or-refund policy for certain cases which I hardly find with other immigration law firms. This speaks for itself of their expertise and confidence in what they are doing. Without hesitate, I highly recommend Chen group to anyone who would like to obtain their I-140 NIW.
  • Postdocoral

    I never forget those frustrating days of choosing a law firm for presenting my I-140 EB2-NIW case. Through a friend referral I came to know about Chen Immigration law group. He got his green card with the help of Chen group. He never had an in person interview or even phone conversation with them throughout his case filing process which that made me skeptical of choosing Chen group. Long story short, I made my mind and chose Chen group for my case. I admit that their money refund policy offered to me was also effective! Going through the process of I-140 case preparation, I found this firm very precise and meticulous where they provided me every answers and comments in a timely manner and in accord to their given timelines. I loved their cover letter written for my case, it seemed a person who was very familiar with my research drafted the letter. My case finally got approved without any RFE after over 10 months. Now I reiterate my friend experience that, working with Chen group helps you to go smoothly through this overwhelming process without even a phone call or in person visit with them. I appreciate Chen Immigration law group which helps people like me to get away from all visa headaches.
  • Postdoctoral research associate

    I would like to thank Chen Immigration law group for a superb work on my case. Few days ago I got my I-140 EB2-NIW approval after 4 months. During that time I was issued RFE and with an outstanding help of the Chen group the RFE was effectively addressed and submitted in a timely fashion. Therefore, I would highly recommend the Chen Immigration law group for anyone considering permanent residency application.
  • PhD Candidate

    I received the approval notice of I-140 a few days ago after close to 3 months processing. It was great to work with Chen group. They make everything easy and all the time they are supportive. I really appreciate them and definitely recommend them to my friends.
  • Postdoctoral Research Associate

    I just received the I-140 approval notice by mail a few days ago. I really appreciate all the help from North American Immigration Law group. Chen group has detailed instructions for the case preparation that make all the thing easier. Not only that, people in Chen group are very nice, expert, and efficient on everything. They always provide the detailed answer for every question that I asked, no matter how small the questions were. During this application time, I also received an RFE. That was frustrating. But Chen group help me so much for the REF response and we finally summited the REF response before deadline. I sincerely recommend North American Immigration Law group to all my friends who are working or considering green card application.

    Post-doctoral Researcher

    I wanted to sincerely thank the team at North American Immigration Law group for all their help. They are an outstanding group of people and it was a pleasure working with them. I worked with them for both my I140 and I1485 in the EB1A category. Prior to starting the process I had talked to several lawyers. While everyone was ready to take my case, Ms. Chen and her team were the most critical and identified one potential area (number of reviews) that I could improve on to make it stronger. Thus I spent quite a bit of time on it and as a result my I-140 went quite smoothly. They were extremely meticulous while preparing the application package. I was very impressed by their understanding of the research statement that I had provided, which reflected very well in the letters (both application and reference).

    Personally for me the process of I485 was long and stressful. Being an Indian the adjudication for EB1 was closed for several months both in 2016 and 2017. Additionally due to this I had received a medical RFE as well. They were always very helpful providing valuable advice, followed up with USCIS when required and applying for my EAD/AP renewal in a timely manner.

    Throughout the whole process they were extremely helpful, very professional and responded in a timely manner. I have recommended all of my friends who are planning to apply for their green card to contact the Chen group and I would unreservedly recommend everyone to do so.
  • Assistant Professor

    I received the e-notification of my I-140 approval yesterday. I have really enjoyed working with the Chen group. The case preparation process took about 4 months. Before contacting Chen's group, I had no idea what was involved in the green card petition process. But Chen's group was very patient in answering all my questions, but was also very fast and responded to most of my questions within 24 hours. I also liked that they would provide a free evaluation of your case and provide approval-or-refund service if you met certain criteria.

    The Chen group is definitely a lot faster and more reliable and helpful than other law firms that I have personally worked with or heard about from friends. I really appreciate their work on my case, and I would definitely recommend this firm to other people.
  • It was a very good experience to work with the Chen group to get my I-140 approved. I was impressed with their great attention to details, timely response, quality of service, and sense of responsibility for their clients. I'm actively encouraging all who think they have the minimum requirements to contact Chen immigration group and see if they can start a filing process. Once again, I appreciate the firm for their work on my case.
  • I am really happy that I filed my I-140 with the Chen group. They are very responsive, they know all of the details of their job and I had a very good experience with them applying my I-140. I highly recommend them and advised all of my friends who want to apply for NIW to use their help.
  • I would like to thank Ms. Victoria Chen and the Team from North American Immigration Law Group for their excellent service for my case. I retained Chen Firm for my NIW case. During the process, I found their service professional and timely. Attorneys answered my questions with accuracy and in a timely manner. The Team was digging into the research summary and materials I provided, and the petition letter and the whole package were prepared in a perfect way that I am very surprised and appreciated. The case were submitted and we got RFE. The Team responded quickly with a RFE strategy. The response to RFE package was mailed back in time and within two week after RFE response received, my case was approved!

    I would highly recommend Ms. Victoria Chen and her team for their professionalism and excellence service.It was really good to have such good attorney for my NIW petition. I am very fortunate to have the NIW journey with North American Immigration Law Group. Thank you very much!
  • I got my I-140 (NIW) approval notification last week. I would like to thank Ms. Victoria Chen and all her legal team @ North America Immigration Law Group for their excellent, professional and very efficient work. My case was approved in less than 90 days without RFE. Without their help, it would not be possible. I will continue to work with Chen Immigration Law associates for my I-485 application.
    I already recommended their service to my friends and will continue to do so in future.
    Thank you very much; I am so glad that I chose Chen Immigration team.
  • Assistant Professor

    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.

  • Postdoctoral Associate

    I would like to thank The North America Immigration Law Group for their great work on preparing my I-140 petition, which has been approved recently. I appreciate all their work from the beginning including carefully evaluating my case and answering my questions to choosing the recommenders, writing and filing the petition. During this process, there were a couple of times that I was fascinated by their expertise and experience in preparing NIW petitions. As an example, I realized that they checked the number of citations every time that the petition was revised and updated it on the petition by the time of filing the petition. They are also punctual and have a deadline to prepare the recommendation letters, petition and answering questions.

    In general, they are very professional and everyone can simply trust them.

    I am so grateful to The North America Immigration Law Group and I highly recommend them for filing NIW cases.
