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.

    Director of Technology

    My EB1B petition with Premium Processing was approved within 10 working days.
    My colleague recommends this great law group to me, since he also got his petition approved smoothly and fast with their service.
    No doubt, this law group is professional, careful on every detail, responsible and patient with every question you have.
    When preparing the petition, they are experienced, high quality and quite fast compared with many other law groups.
    Considering the immigration is one of our most important legal affairs, we should choose the best.
    Based on what I have experienced, Chen Immigrations and Attorneys is the best.
  • Postdoctoral Scholar

    My EB1a petition with premium processing was approved in 9 days! Initially, I had reached out to a handful of law firms with my credentials and the possibility of filing for permanent residency. Ms. Victoria Chen was the most upfront about my qualifications and discussed my case objectively. After retaining their firm, I realized that the Chen Immigration Law Associates is professional, superbly organized, and courteous; they did an excellent job of preparing my case, which included writing five excellent recommendation letter drafts and an extremely convincing petition letter. I am particularly impressed by their secure case management system, and how quickly and efficiently they deal with client questions and meet deadlines.
    I strongly recommend the Chen Immigration Law Associates (wegreened.com) for your I-140 immigration petitions.
  • Post-doctoral Scholar

    I would strongly recommend anyone for filing their EB1A I-140 petition through we greened.com. They are timely, thoroughly professional and their service is excellent. Moreover, they are extremely careful in the case preparation and filing the application in time. My EB1A is approved without any RPE which is a welcome news. Definitely, we greened.com has a great track record of success and i strongly recommend for anyone applying through EB1A category.
  • Postdoctoral Fellow

    I am glad to know that my EB1 I-140 is approved. You made my dream come true. I am very thankful to North America Immigration Law Group. In addition to one's extraordinary credential, it is very important to have very good attorney for this success. Chen immigration attorneys are very brilliant and professional. They are very prompt in replying every query.
    My several friends recommended Chen immigration and indeed they are great. I worked with Ms. Chen and Mr. Ingebritson. They have explained and simplified all process. Their wining strategy of selecting most useful credentials and presentation helped me in success of my case. I am completely satisfied with their service and highly recommending to everyone who is interested in employment-based green card application.
    Thank you very much for all your help and advice during entire process of my application.
  • Senior Scientist

    Chen Immigration Services is the best immigration lawyers group in the United States. Why? This is the list:
    1) They will evaluate your CV and will recommend which option is best for you and they back their recommendation by money back guarantee if your case is not accepted by USCIS. I don’t think any other lawyer group will do that.

    2) They are best in replying/answering your questions/concerns at every stage. I personally emailed them almost on a daily basis and got reply to each of the questions on the next business day, as they promised on their website, with no exceptions.

    3) They are always in time in every step of the application process. Be it I-140 draft preparation, recommendation letter preparation, they are always in time. Whatever timeline they have promised in the beginning; they have always kept it. To me, that is exceptional service and probably cannot be matched by any other company.

    4) Their recommendation letters are really well thought out, scientifically correct (good content writer), and above all accurate in terms of describing scientific contents in layman’s language that everybody will be able to understand your research significance.

    5) Even when I disagreed with them, their explanation convinced me that they are doing right thing to get my application approved.

    6) They went above and beyond to accommodate my special need. In the middle of our GC application, we moved from one place to another, and since it was a new construction and USPS did not yet start delivering the mails at our address, they accepted all the mails from USCIS and sent us via FEDEX as we requested.

    I really appreciate their business and I strongly recommend Chen Immigration Service for your immigration need.

I am 100% satisfied with your service and without doubt I definitely would recommend your law firm to anyone I know. Thank you your entire team member for help and guidance.
  • Research Scientist

    So excited to know my EB1A was approved this morning without RFE. My case was received on 2/13/2017 and only took 4 days to be approved. Wonderful job!!
    I am very satisfied with the service of Wegreened. Very professional. I only regret that I did not seek help from them earlier thus wasted a lot of time and money elsewhere.
  • It is the best news to me and my family that my EB1A was approved recently without any RFE. Thank you so very much for all the help you offered on each and every step of my application. It is a great pleasure working with you and your team. I will be more than glad to refer you to my friends.
  • Associate Research Scientist

    Thank you VC associates for helping me file my EB1A petition! Working with Chen associates has been a wonderful experience. I really liked their step by step approach to building the petition and their advice was very clear and to the point. I was pleasantly surprised that they did really good research on my area of study and the reference letter drafts reflected that detail. My approval came without any RFE! Thank you VC and associates for helping me with my petition, and I will most definitely recommend them to my friends and colleagues.
  • Postdoc

    It is very much a surprise and a valuable gift that my EB1A case is approved on the Valentines' Day. I have been working with Chen Immigration since November last year, and the whole process was very smooth and efficient. The team helped to address my questions timely and accurately, all through the procedures of preparing the recommendation letters, petition letter, and various forms, they have also carefully helped to answer my questions in terms of visas and overseas traveling, which were very helpful to me. I didn't change even a single word of the recommendation letters that the law team drafted for me, the letters were excellent and my recommenders also think so, and eventually all my recommenders agreed to sign the letter without any modification. I will definitely recommend Chen Immigrations to my friends and colleagues. Thank you very much!
  • research fellow

    I had a very pleasant experience with Wegreened. I consider my EB1A case a not very strong one because I only had 60 citations from my 8 papers. I sent my evaluation request to three attorneys and only Wegreened agreed to work on my case. The entire process was smooth. I really like that they drafted my six recommendation letters very well, and I almost kept them as they originally were in the final version. I had a lot of questions during processing and Wegreened always replied within 24 hours to address my problem effectively. In the end, I was thrilled that my case got approved in as short as 2 days after I filed premium process request. Here I want to express my gratitude to Wegreened for their help. Also I hope other people who want to file EB1 but do not have a very strong background will consider Wegreened, and hope you can have your immigration dream come true as soon as possible.
  • Visiting researcher/Post Doc

    It is such a pleasure to share my experience working with Chen lawyers. I first contacted Ms. Chen in the end of 2015 and she went through my CV in detail. Although I had a decent number of publications and citations, I had no review experience till then. Ms. Chen advised me ways to improve my profile to apply for EB1A, (need I say the most priceless advice ever). There was no reason for her to do so, she is already well-known and at that time we hadn’t signed our client-attorney contracts. I took her suggestions seriously and worked for a year until I reviewed enough papers for journals before I enrolled with her. The review process also helped me in establishing contacts with some great editors, which was highly beneficial in a sense that some of them later were willing to sign my recommendation letters.
    Working with Chen’s team is so smooth. Her team is highly professional as well as meticulous – they go through every minute details of your case and respond to your queries within 24 h. The RLs and PLs they drafted for me were exceptional I didn’t need to modify them. My EB1A got approved in just 8 days, without any RFE hassles. She has more than enough recommendations and success stories to share, nevertheless let me say this – her team can make it happen for you.

  • I got my EB1b approved in 12 days or so. Very professional staff headed my a great attorney Victoria. Green card strategies are highly streamlined and the attorneys really know what they are doing. Don't make a mistake of not hiring them. They are best in the business and I experienced that first hand.
  • Postdoc

    My EB1a got approved in 13 days. It has been a great experience working with WeGreened. The team is very professional and my questions are answered within 24 hours. The petition letter is well written and I almost made no changes. Overall, I am very satisfied with their work. I highly recommend anyone who wants to apply for green card. I have recommend WeGreened to my close friend to apply for her green card.
  • Postdoc

    I want to express my deepest gratitude to Wegreened to help me successfully apply for the EB1A. It was a long journey and took tremendous effort. I really cannot imagine any step further without the professional help from Wegreened, due to the loads of paperworks and multiple revisions- the requirements are even more critical than a professor, but they try to make every single step perfect and even better. They did a GREAT work.

    Thanks to the extraordinary professionalism of the Wegreened Attorneys, I was able to go along all the procedure, without fear nor headache. At the beginning, I barely had a clue of anything, I don't even know the difference between EB1 and EB2 (I guess I am the kind of the person who only cared about research, and I bet many of the potential clients are like me). Wegreened provides many internal resources to help a person like me to get started, not lengthy, but clear enough to explain the whole procedure. During the application process, I kept asking questions frequently (many silly questions I admit), and they are always there, always patient, always helpful and responsive (they have a very well designed response system, very convenient to use and they can response usually within one day).

    During the application process, there are also tons of paperworks to be prepared. Wegreened also helped revision again, again, and again and again, until it is completely satisfactory. They could find out even tiniest flaw that may hamper the application, even more picky than a reviewer of a high-profile journal, but I am totally convinced since they always have a reasonable point. It is also amazing seeing that as attorneys, they could even followed the logic of my field, writing right letters capturing the real main and shiny points (If you want me to write sth out of my field there is no way I could do that).

    If you never had this kind of application experience, you may find me (and the people downstairs) kind of boasting for them. Believe me or not, I am not exaggerating at all. The application is like hundreds of pages of materials, at the end I don't even believe myself - that's a lot of things!

    Last issue is about fee. I know some people like myself are worried about the cost, since I really don't earn much by giving up company offer and choosing a postdoc life. Now after the whole lengthy procedure, I think the fee is totally worthy, not to mention the refund policy. The EB1A is sth happening only once in a life, so if you take my suggestions, just let the professionals like Wegreened do their job. They save so much trouble, and they are professional among professional, they know what they are doing.

    Overall, I recommend Wegreened with highest enthusiasm.

Success Stories: NIW Petition Approved for California-based Postdoctoral Researcher from Iran in the Field of Biomechanics

I started my NIW process with Chen Attorney on August2015, I submitted my NIW application on Dec 2015, and my case got approved after 8 months. I think Chen Attorney is the most successful attorney in NIW approval and they know what to do, what to write in letters of recommendations, and your application letter, and what documents to submit. It was very convenience working with them in the whole process and when I had a question, it usually took me less than 2 business days to receive a response back from them. The letters of recommendations and the cover letter were very different than what I thought could be, but I trusted the way they wrote it and just spent some time to edit them. Of course they were not expert in my field and some parts required major revision. In general NIW application requires a lot of your time and money. In the end, I am very happy working with them and comparing with my friends' cases working with other attorneys, I really recommend Chen Attorney for NIW application. Also, they usually give you a "do it yourself package" for filing I-485 for free, which is almost all you need to file I-485. We used that package and filed our I-485, and we got approved 4 month after the NIW approval.

I am extremely satisfied with the way Chen Immigration Group has handled my case. At every step, I had lot of questions and they patiently answered everything. They drafted excellent letters of recommendation with lot of technical inputs from me. The top quality letters and highly persuasive response to the RFE was the biggest benefit for me that led to a definite approval. They found the strongest possible evidence from my records. As a matter of fact, these were evidences I may have overlooked due to a lack of understanding of what immigration officers look for. I am happy I chose Chen immigration to represent me. Recently (Jan 10th 2017), I also received my green card after I-485 was approved. I am happy to start my journey as a permanent resident in this country and extremely thankful to Chen Associates for their valuable service.
