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 6,000 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.

    My friends recommended contacting Victoria Chen for the Immigration petition. I contacted her in late November 2016 to enquire regarding my chances for EB1A petition approval and received a reply within couple of hours that they should be able to qualify me under the EB1A category with their "Approval or Refund" service. I signed the retainer agreement on November 30, 2016 and was provided excellent service throughout the case preparation and filing. They are very professional and always ready to help you with any concerns/questions. In a nutshell, they know what they do. Today, on April 20, 2017 my I-140 got approved after two weeks of submission (pp requested). Thanks a lot Victoria Chen and group for your excellent service. Keep it up and stay blessed!

    wegreened simply says it all. They work to get us green card no matter what after they take up our case. I would like to sincerely thank the wegreened team for their valuable guidance in my EB1B petition. I started with free evaluation and they suggested EB1B as my best bet and also provided "approval or refund" option. They were very professional and timely during the entire process and at the same time were very patient and considerate in answering my queries or questions. The best thing about them is that they know how the USCIS people judge or review the case and how to avoid unnecessary harmful language in recommendation letters and petition letter. They drafted recommendation letters completely differently (not even single sentence matched) which is very important and I think that's why they draft all letters together. Also, 95% of my hundreds of questions and queries were answered within a day. I got my I-140 approved within 8 business days (premium processing). Thank you wegreened. igreened because of wegreened. I highly recommend their service for GC. I already referred many of my friends and they started their process with them as well.
  • postdoc in Ohio

    We contacted Chen immigration attorney last August. They promised for “approve or refund”, which made me confident with their firm. After comparing with others, I signed with them around December.
    Their group is very professional, their responds were quick and instructive, all I need to do is to follow their guidance, using their templates. I submitted my I-140 for Eb1A in later March and was approved in less than two weeks with premium processing requested.
    Highly recommend!
    祝大家好运!
  • I would like to sincerely thank Victoria and the Wegreened team for the professional manner in which they handled my I140 case. all questions were answered in time, no deadlines were missed and everything was routine. I have already recommended her to some of my friends at work. Could not have done it without them. Definitely going to go with them for visa as well.

    Thank you

  • Instructor, Department of Medicine

    I contacted Chen immigration attorney in early August, 2016 to enquire regarding my chances for EB1A petition approval.Upon which the attorney replied in less than 24 hours with a approval of money back guarantee upon reviewing my case. I was provided excellent guideline and step by step logistics as to how i would proceed with my application and preparation of material in the following few month. Upon receiving my research summary the attorney drafted extremely high quality documents in support of my application. They emphasized and focused primarily on the highest outcomes and exposure of my work at national and international level providing only the highest quality of my research work summary for review by the USCIS officers. This extraction and presentation of my best work was expertly done by the firm and I believe that this was the reason for the success of my application.

    I would highly recommend this firm for any kind of immigration petition preparation as they are the best in the business, extremely professional and very easy to work with.

    Usually immigration work is extremely stressful , but Chen immigration step by step guidance and immediate response policy helped me endure this process smoothly and successfully.

    I highly recommend Chen Group. I submitted my I-140 with a request for PP under EB1B category. USCIC received my case on 03/28 and after 8 days it was approved with no RFE. I have retained them for I-1485 as well. I would like to thank Victoria Chen and her team. Could not have done it without them. NAILG was recommended to me by a friend who used their services and was successful in obtaining his GC. I have passed on the torch and have already recommended this group to my friends who are in the process of applying for a GC. They are very professional, meticulous and the quality of their recommendation and petition letters is outstanding. I am very satisfied with them and again highly recommend them.

  • Postdoctoral Fellow

    I would like to sincerely thank Victoria and her team for the very professional manner in which she handled my case. From the free evaluation stage till my I 140 approval, all questions were answered in time, no deadlines were missed and drafts were sent to me on or before the day they were due. I have already recommended her to three of my friends at work. Could not have done it without them. Definitely going to go with them for I-485 as well.

With meticulous case preparation and highly professional work by Dr. Chen and his team, my EB-1A got approved within 10 days with premium processing.

    I would like to pass my sincere gratitude to NAILG for handling my case in a very professional and efficient way. Because of the efficient and timely effort on part of NAILG, I never felt the need to work with an immigration law firm not situated within my close proximity. One quality I believe that has made NAILG one of the leading firms for EB1/EB2-NIW petitions is their professionalism and thoroughness while working on a case. They were always prompt to respond to any queries I have had during the course of filing my petition and getting approved eventually. I was pretty confident that if NAILG chose to take my case, it is reasonable to believe that the probability to land an approval for my NIW case would be highest. I also acquired their service for my Adjustment of Status (AOS) application and highly recommend all the potential NIW applicants to get their credentials checked by NAILG and retain their service without any hesitation. I wish more success for NAILG in coming days.

    My EB1A I140 peition filed through NAILG was approved recently. When they offered their best "approval or refund" deal, I was excited because I understood that this deal meant a 99% chance of success. Apart from the outstanding and extremely professional work ethic and high responsiveness (which thousands of people like me, have time and again attested to), I had an educative experience preparing my research summary according to their guidelines. Their guidelines gave me an opportunity to see my own research in new ways. I also studied the papers that cited my work and it opened up my own understanding or the scope and application of my research in novel directions, which I had not been aware of earlier. Their offer of the I485 DIY kit is also a strong testimony to their integrity and concern for their clients. I would wholeheartedly recommend their services to anyone seeking professional help (many of my friends are already working with them). I also sincerely thank Dr. Chen and her team of outstanding attorneys for brining about positive changes in our lives.

    My I-140 for EB-1A was approved in 2.5 months (14 days after Premium Processing). It was a very pleasant experience with the North America Immigration Law Group. They are very professional from drafting high quality recommendation letters to finishing the final petition letter. The whole process was very smooth and efficient. The response to my questions was timely and accurate. I am completely satisfied with their service, and highly recommend Chen immigration to anyone interested in EB-1 or EB-2NIW categories.
  • National lab
    Post Doctorate research associate

    Couple of my colleagues (both were postdocs at that time) at my lab got approved for EB1A through VC and associates. Also, VC already had a good reputation in the immigrant community at my lab. So, when I felt I am ready to apply for EB1A petition, I contacted NAILG. After looking at my CV and citation record, they offered me approval or refund (R) guarantee to which I am pleasantly surprised. I retained them for both I140 and I485 case preparation. Here are few things that impressed me:
    - Secure case management portal where you exchange numerous emails, questions and documents in an organized way.
    - Very high standards of document preparation. Well, EB1A itself has stringent requirements for approval, so high standards in case preparation is much needed. It took me few weekends to prepare research summary according to their template. This is the most important task on applicant side. I felt more information one provides in research summary the best will be his RLs and PL.
    - Excellent recommendation letter drafts. I did edited only technical content of them for more accuracy.
    - I was astounded once I had seen the PL. They interlaced my achievements with most objective and statistical legal information and presented a water tight case. I am very impressed with the quality of the PL.
    - They are very professional. However, sometimes I felt they are stiff with timelines and not accommodating to the changing needs of the client. They impose the retainer agreement very stridently.
    - Lot of information. They have a troves of guides and manuals to prepare i140 and i485 documents. They provided detailed form filling instructions for all the forms we are supposed to fill. They also provide timely information on latest immigration trends, government notifications etc.
    - Very thorough case preparation. When, I am sending i485 documents ( which is a lot of documentation) I checked them 4-5 times felt everything is alright. However, they pointed out numerous minutest mistakes. I was pleasantly surprised.

    My I140 got approved in 8 days and I am waiting for i485 approval. I wholeheartedly thank VC and associates for all the professional help in case preparation.

Success Stories: EB-1A Petition Approved in 11 Days for Senior Research and Development Engineer in New Jersey in the Field of Computational Engineering (PP Requested)

After having an unsatisfactory experience with another law firm wherein no petition was filed, I decided to hire Victoria Chen and associates to file for my self-petitioned EB1A green card, and I could not be happier about that decision! She is extremely meticulous and detail-oriented, and very prompt at responding to questions/concerns. I was very pleased with the management of my whole case. Every statement in the petition letter had evidence to back it up, making the case stronger and stronger with every iteration. Even though the whole case management from start to finish was electronic, I never felt the need to speak to any of her associates on the phone. Although every case may differ, with her assistance, my application was filed within 4 months. She is highly skilled in her field and comes with my strongest recommendation. Thank you so much for your help!
