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.

    I recently received my I-140 approval notice under EB1-A. We submitted my petition through premium processing, and I got the approval notice within 8 days. I am very thankful to Chen Immigration Law Associates for their help and guidance at each step in the preparation of my case. I really appreciate their critical thinking and commitment throughout the process. I highly recommend the North America Immigration Law Group for their professionalism and highly experience team.
  • University of Hong Kong
    Research Assistant Professor

    My petition was approved 7 DAYS after the USCIS sent me Premium Processing receipt notice in early Dec, 2017. Thanks to the Chen Immigration Law Associates! I contacted Chen Immigration for EB1-A petition in Aug, 2017. I was so impressed by their high-quality professional work during past 4 months. Their guidance on application procedure and document preparation was very clear so that I followed it very easily. Most importantly, they really spent time and tried their best to understand my research background, which I think is critical for drafting a perfect petition letter. In addition, their online communication platform with clients is friendly to use and efficient, on which their attorney team always replied my questions within 1 working day or follow up required actions within the time they committed in the contract. Therefore, I would highly recommend the Chen Immigration Law Associates if you would like file an EB1-A petition.
  • Postdoctoral Fellow

    Thank you very much for your time and efforts. My I-140 was approved in the early December. Chen Immigration group handled my case properly and professionally, and they spent a great amount of time in understanding my work and making sure we are in the same page. I would highly recommend the North America Immigration Law Group to my friends, if any of them are going to submit their applications to EB-1A or EB2-NIW. Thanks so much.

    Postdoctoral Researcher

    I contacted Chen Immigration Firm around December 2016 and shared my profile for EB1-A petition for I-140. The official process started around January 2017. I started mustering all the required documents and Chen firm was always on top of things and did a great job in drafting recommendation letters and final 25 pages-petition letter. The chen firm certainly worked rigorously on my case. All my queries were answered withing 24-48 hrs. I was really impressed by their promptness. I submitted my final I-140 to USCIS (around first week of June 2017), decide to PP and received approval in 13 days after PP. My I-140 experience was without any hiccups of RFE, etc. My experience with Chen firm has been really awesome and so I decided to retain their services for I-485 as well. I highly recommend Chen Immigration Firm to all the EB1-A petitioner researchers in sciences.

    My EB2-NIW got approved last week, after 10 months from the filing date. I would like to send the huge thank to the Chen immigration law group for their professional service. I was recommended by a friend who also successful obtained Green card through working with Chen Immigration and Attorneys. And it was a valuable recommendation for my application. Victoria Chen and her team have done excellent works in handing my EB2-NIW case. Although I am very confident about my profile, but without their well-written petition letter, drafts of recommendation letters, and well organizing of all documents, I would not get it approved that smoothly. In addition, their writing services have helped me a lot in reducing the workload to prepare for filling. Mostly i only had to proofread and make some small changes for recommendation letters and petition letters. Especially in my case, when we were ready to file the I-140 application, there was the sudden change on the national interest waiver standard, the Matter of Dhanasar. However, Victoria Chen and her team reacted promptly and revised my petition letter in a short time. Definitely, they are full of experience in preparing the documents for the immigrant petition can grant your success. I have been recommending, and will recommend the Chen group to anybody wishing to apply for a permanent resident petition.

    I just received the EB1A I-140 approval notice by mail a few days ago. I am greatly thankful for all the help from North American Immigration Law group. Chen group did a great job in my case, they were perfect in timing and documentation. I signed the contract with Chen group in the last week of July, 2017 and got the I-140 approval in the first week of December, 2017 without any RFE. Within four months they prepared all the documents and gave step-by-step instructions for how to complete the whole petition package. They always responded to my queries within 24 hrs and sometimes even in the mid-night which shows the high sincerity and professionalism.
    I would highly recommend North American Immigration Law group to all my friends who are working or considering green card application.
  • postdoctoral research associate

    I recently got my NIW approved. It was a pleasure to work with Chen immigration law firm. They are professional, relaible and super efficient to complete everything on time. I will definitely recommend your firm to all my friends.
  • I was notified last week that my petition for EB2-NIW has been approved. I sincerely appreciate Victoria Chen and her wonderful law group. Immigration to the United States might be a hard legal journey which can be facilitated by expert lawyers such as those affiliated with North America Immigration Law Group. It was the first time in my life to hire a law group for a legal reason. Although I never met these nice people and everything happened online, they have been the most trustable professionals one could encounter in life. They zealously worked on my case and every single question was responded in a timely manner through their secure communication system in the past months. Moreover, once an RFE requested by the USCIS, they worked again intimately yet professionally to resolve the situation. Based on my experience, the services provided by the NAILG were much more than my expectations. If you wish to get your case approved by this trustable and professional law group and especially if you are an individual with an advanced degree or remarkable ability, just be patient and stay faithful to this team and the results will be amazing. They know what they do. Good luck!

  • Chen Immigration is a highly professional law firm. They worked with me on my EB1A petition. They gave me an initial evaluation before I signed with them for the ‘approve-or-refund’ service. During the entire EB1A petition process, they answered my questions promptly and gave me invaluable advice on preparing the petition. They have always stuck to their promised deadlines during the petition preparation process. I highly recommend their EB1A services.

    I had worked with Chen Immigration group for my O-1A visa first and then retained with them for my I-140 petition under EB1A category. Their services are rapid and prompt with an affordable fee structure. They also have very high success rate of approvals. They have taken utmost care on all the required documentation. They usually respond to my questions in 1 business day. I highly recommend Chen Immigration group for my fellow colleagues for their petitions under various categories.
  • I had Chen group to petition EB2-NIW for me. The petition got approved after 11 months. I am quite pleased with their services. They are very professional and they know how to write an effective petition for the applicants. Don't assume that they have a pre-written draft and they just make few changes for their applicants. They write the petition exclusively for you. They are also very quick in responding all your questions within a business day (sometimes the same day).
    To sum up, I would highly suggest this amazing group for anyone who wants to apply for EB2-NIW.
  • Working with Chen Immigration Group is a very enjoyable process. They are very knowledgeable, professional and ready to help at any time. Their strong expertise and guidance are the keys to have all materials well presented and strongly organized. They've definitely played a critical role in my I-140 (under EB1A) approval. Really appreciate the wonderful work done by Chen Immigration Group! Highly recommend them for the immigration application!
  • Recently, my EB1A was approved and I really appreciate North American Immigration Law Group’s support and excellent service they provided. Considering my case is not very strong for EB1A, they drafted petition letter that highlights my research which eventually got my case approved. I hardly changed my petition letter since I received from my lawyer. They are very strict with time for each process and always respond my question within 24 hours. I would definitely recommend Chen Immigration Law Group for anyone preparing permanent residency application.
