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 would like to thank Victoria Chen and her team at the NAILG for their help in preparing my I-140 and RFE packages. They were in touch during the whole process and also quick in replying to every query. I got my I-140 approval within 23 days of filing the RFE. I will continue working with them to file my I-485 package.

    I would highly recommend the NAILG for EB2-NIW case filing.

    Thank you very much again!

    I appreciate the help and guidance of Chen Immigration & Attorneys in preparing my NIW case.

    I contacted them when I had just heard about NIW. Using the info on their website and with their free evaluation, I reached to a point of confidence to start preparing my supporting material. That was also a convenient and easy-to-follow process thanks to them and their detailed instructions. My case was approved after 90 days with no RFE.

    I would highly recommend them to friends and colleagues for NIW cases.

    I thank Chen immigration Attorneys for their great service in carefully preparing my I-140 application/petition. Today, the 12th day after the I-140 premium petition submission I received the approval notification from USCIS by email. Starting from the preparation of summary of contributions through petition filing, a whole lot of processes in less than 5 months, I was always supported by the Chen immigration Attorneys with timely replies to my queries, impressively with best professional solutions. Thank you Ms Chen and her Team! I will always recommend your service to my friends in the future. I also thank you for providing me with your complementary DIY packet for I-485 application.

    Thanks

    I would like to start by thanking Victoria Chen and her team of absolutely amazing people at the North American Immigration Law Group for their hard work and dedication. It was a pleasure working with them in every stage of my NIW process. Everything was handled extremely professionally and well. Their return time to my specific questions was fast and I always got the answers i needed. I am very happy that I decided to work with this law firm on my NIW application. It was one of the smartest choices I made. I highly recommend that you choose Att. Chen and her team to handle your immigration needs.
  • Control Systems Engineer

    I would like to thank Att. Chen and her team at the North American Immigration Law Group (NAILG) for handling my case for EB1-A green card application. From the beginning, the attorneys were prompt and extremely clear about how they wanted to build my case, and how to best put forward available evidence to build a strong case. I appreciate their attention to detail in preparation of my achievements, which weeded out a few ambiguous points, and retained only those that could be backed by documents. All their responses were always within the times they specified in their agreement.

    Once my documents were in place, they promptly prepared my application packet, and filed it with USCIS. Their hard work paid off with USCIS approving my I-140 application within 10 days of filing (we had requested premium processing).

    Once again, thank you very much for preparing my case for the green card. I would be glad to recommend NAILG to friends and acquaintances for processing of green card applications.

    First of all, this is my sincere apologize about some thoughts. When Dr. Chen or one of his crew were asking about removing a number or inaccurate word or insignificant statement from my application, I was unhappy and I was saying why they care about such details.
    Now, I got it. My I-140 has been approved after two months from its submission. I really need to mention my apologize and let them know that you did a great job better than anybody even the applicant himself.

    Thank you so much and of-course, I recommend you for everybody else applying for NIW or other immigration applications.
    Regards,
  • Optical Engineer

    I want to express my absolute satisfaction with Chen Immigration & Attorneys. Chen handled my I-140-NIW case in a very professional manner and replied to my questions promptly. Throughout the time of the application, USCIS made several changes to the process (Visa retrogression, Dhanasser case, introducing interviews to I-485, etc..) so the process was very stressful and things could have gone wrong very easily. Having experienced firm handling my case was a key for setting things in the right direction from the beginning and avoiding any further delays or RFEs.

    I highly recommend Chen Immigration & Attorneys and I always advised my friends and colleagues to contact Chen for handling their cases.
  • Postdoc

    I would like to highly recommend Wegreened/Chen Immigration Group. They were very professional, and replied to my many emails promptly and really helped me a lot in getting the approval. I am extremely grateful to them for all of their help. I am very happy I chose them because comparing my experience to the experience of some of my friends with other lawyers, i am certain that Wegreened/Chen Immigration Group is the best.
  • Food Scientist

    I had great experience working with Wegreened/Chen Immigration Group, and I am extremely impressed by their efficiency and professionalism. The communication through their web portal was very efficient and my questions were always answered in a timely manner. All of the drafted documents were prepared on time. The whole process was smooth and every single detail of my case and documents was evaluated thoroughly. I strongly recommend Wegreened for anyone's green card application.
  • Researcher

    I would like to highly appreciate Chen Immigration & Attorneys because of their mazing job.

    They were great at every step from the evaluation to drafting the letters and submitting my application.
    They are very professional in NIW green card category with a reasonable attorney fee. They are very quickly responding all my concerns.

  • Assistant professor

    My experience with Chen attorneys has been very pleasant and they performed a marvelous job at presenting my case. They provided timely instructions and above all their response to my queries was perfect.Thank you.
  • Chemistry researcher

    The attorneys @ Chen immigration are extremely professional, dedicated. and detail oriented. They provide free and accurate evaluation of each case before they agree to handle it and petition for it. During the whole process of filing my EB-1A, they provided step-by-step guidance such that the process was never overwhelming at any point. Drafting of recommendation letters and testimonial letters is an added benefit, since very few lawyers provide this service. Moreover, the recommendation letters and the petition are based on the facts and figures you provide and they don't embellish anything. This I guess is the secret for their success. Thanks to the whole team for getting my EB-1A approved!
  • It's been a great experience working with the amazing Chen Immigration team... I would like to thank the whole team for getting my EB1-A approved.. Looking forward to continuing this "team work" for the next steps.

    Thanks,

  • 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.
