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. degree 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 petition. 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 5,000 EB-1A, EB-1B and EB-2 NIW approval notices. In 2014 and 2015, the approval rate is 98.22% for cases using our Approval or Refund® (money back guarantee) service and 96.95% for all kinds of services.

For NIW cases, the approval rate is 99.18% for cases using our "Approval or Refund®" (money back guarantee) service and the overall approval rate for all NIW cases is 98.47%.

For EB1A cases, the approval rate is 97.25% for "Approval or Refund®" (money back guarantee) service and the overall approval rate for all EB1A cases is 95.27%.

We are one of the leading U.S. immigration law firms providing the most comprehensive services for EB-1/NIW petition with a large volume of approval cases and high approval rate.

*The number of approval notice for EB1B cases is under-estimated of the total EB1B cases we successfully petitioned because many EB1B employer petitioners did not submit G-28 and we are not the attorney on the record.

*Our approval rate is 98.47% for all NIW cases and 99.18% for "Approval or Refund®" (money back guarantee) NIW cases.

*Our approval rate for all EB-1 cases is 95.36% and 97.21% for our "Approval or Refund®" (money back guarantee) EB-1 cases.

*The approval rate statistics only include cases that were originally filed by our law firm and exclude RFE (Request for Evidence)/NOID (Notice of Intent to Deny) cases that were taken over in the middle from other law firms or DIY clients.

*In 2015, all our EB1B denials and many of our EB1A denials were issued by the same immigration officer working in Nebraska Service Center. This officer holds a significantly different adjudication standard from the rest of the officers. Without exception, the officer firstly issued a generic template NOID (Notice Intent to Deny) or RFE (Request for Evidence ) without addressing specific evidence submitted or raised specific challenges. After our response, the officer issued another template denial, without addressing any information in our RFE/NOID response.

*Most of the denied NIW cases are from the same immigration officer working in Texas Service Center, who, similarly, always issued template RFEs (Request for Evidence) and denials without addressing evidence submitted. Clients with similar credentials as those in the denials were able to get approvals from other officers.

Client Testimonial

  • Sr. Engineer at Medical Devices company

    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!
  • Oil and Gas Industry
    Electrical Engineer

    I came to know V.Chen from my friends. At first, I thought that my profile was not strong enough to go through the process of NIW. However, I took advantage of the free evaluation facility of V.Chen which instigated confidence in me that I would be eligible for the process.

    Chen associates has been extremely diligent and thorough in their process of validating my documents. Their process includes multiple checks of the documents to ensure that all the mandatory documents are included in the package.

    Their recommendation letters were very strong, and as a result of their efforts, my EB-2 NIW petition was approved in 12 BUSINESS DAYS!!!!

    Nominal approval time for NIW applications are anywhere between 4 months to 10 months. I have seen lot of people struggling with their applications, but it was great to see that my process went through so quickly.

    I have recommended V.Chen to my friends and will continue to do so.
  • Semiconductor industry
    Senior Engineer

    I came to know about V. Chen from my friends. I am very glad that I made the right decision to choose them for EB2 NIW. They were very thorough during each step of the applications process. The reference and petition letter drafted by them were of very high quality. I would be very happy to recommend them for I140 petition. Thanks a lot.

    I was glad that I had recommendation from my friend regarding choosing V.Chen and her team for my EB2-NIW. Their professional evaluation and high approval rates gave me confidence in my case. They were very responsive to every inquiry I had and provided efficient strategy for my RFE. When I got the approval notice, V. Chen and her team were the first people that I can think of to thank to. It was wonderful working with Victoria Chen and her team.I will highly recommend their team for preparing green card petition. Thank you!
  • Mount Sinai Hospitals

    I scan through many of my seniors before finalizing my lawyer. and 9/10 of mentors/seniors recommended.. One and only "Chen Immigration". They helped me through each and every step down the road. I would recommend potential candidate for any category of green card should go to "Chen Immigration"
  • University of California
    PhD Student

    When I decided to apply for EB2-NIW, I attempted to first do it on my own. I spent six months reading free advice forums on the web and they only made me more confused. I lost six months to learn that I cannot be a master of everything. A friend of mine introduced V. Chen to me and I decided to hire them. I was lucky enough to get the "Approve or Refund" option and it was such a peace of mind to see their amazing approval rates. V. Chen is a group of truly professional lawyers. They handled my case very efficiently and assisted me in each and every step of my case preparation. I had my case approved without any RFE which would have been impossible if I decided to do it on my own.

    Similar to many other Chen clients, I hired Chen associates for filing my I-140 in EB1A category based on my friend's recommendations. From petition and recommendation letters to the last piece of evidence, Chen associates were sound, punctual, efficient, and extremely professional. My I-140 was approved in just 6 days.

    I strongly recommend their services.
  • UCSD
    Postdoctoral scholar

    Based on the very positive feedback that a couple of my friends had, I retained and worked with North America Immigration Law Group for my I-140 immigration petition under the category of EB2-NIW. They have a user-friendly online system, wherein I can leave messages any time I want. Their response to my questions is always prompt, in most cases within a day. The petition and reference letters that they drafted are professional and accurately reflect my previous accomplishments. They also have a clear timeframe for the whole preparation process (e.g. time required to draft the petition letter, etc), so that I knew where we were at. It has been a great pleasure working with them for my case, and everything went very smoothly.

    I will highly recommend this firm to my friends who plan to apply for I-140 related immigration petitions in the future.
  • It was wonderful working with Victoria Chen and her team. I just came to know about the approval of my I-140 in EB-1A category. They are always responsive to all my queries and I will highly recommend their farm for preparing green card petition. Thank you!

    I was referred to WeGreened.com by a friend who complimented their service. I did not expect that they would be that good.
    The first thing that distinguishes them form other immigration attorneys is that they held themselves accountable for unsuccessful petition and they would return the attorney’s fee. Most lawyers do not offer that option. That was what eventually convinced me to go with them.
    Relatively they are not expensive. I checked few attorney firms and they were usually 1000$ more expensive. As it turned out their service is worth all the money.
    They are true specialists in immigrant VISA under classification EB-1A, EB-1B and EB-2. I am a Polish national and I applied under EB-1A.
    They start with the assessment of the case and they advise under which classification to apply.
    Then we sign the contract and then they walk you step by step with how to prepare documentations, fill out forms. Their templates and filling instructions are superb. If there is any confusion they are more than willing to help. They know exactly which exhibits to gather to make a case stronger. Also they beautifully craft all the testimony letters. I heard from the professors I asked for recommendation that these letters were of very high quality. They have seen many of those and they even asked which lawyers I used as my letters were the best they have seen.
    With WeGreened.com everything is done timely. There is plenty of transparency to understand at which step in the petition preparation we are. There is clarity as what needs to get done and when.
    Finally their secure online system where all the files are stored and exchanged is very easy to use and is a fantastic way of communicating. Although we use the internal messages system every time a message is posted the alert is sent to the usual email account as well. There is really no everyday checking. I am really impressed with how smoothly the work of few people can progress thanks to the good online system.
    They are very methodic and true professionals, from my experience the best there are out there. They are also kind, helpful and very willing to assist. I do not have much experience working with lawyers and I am impressed with my experience I have working with the WeGreened.com.
    As to timeline as that was my main concern when we started. We signed the contract for preparation of the I-140 on the 16th of August 2016. We filed on the 14th of November 2016. That took 3 months to gather all the documentation, craft the letters, the petition etc. With a premium processing fee I got the approval decision on the 23rd Of November.
    If you hesitate as how to approach the green card application I so strongly encourage you to go with WeGreened.com. They are amazing!

    I rarely write reviews, however the exceptional quality of legal advice and service that I received from NAmILG has prompted me to write this. Victoria Chen and her entire team are truly amazing in terms of immigration law acumen, competence and above all their commitment. My EB1A I-140 petition prepared by their firm was approved in 11 days. Based on my wonderful experience working with them, I have also retained them for I-485 applications for me and my wife. I will list a few objective criteria that in my opinion make their firm truly outstanding:

    1. Success rate - This speaks for itself. Based on my research online and from publicly available USCIS documents, EB1A approval rates over the last few years has been hovering between ~60-85%. Having an approval rate close to 100% for EB1A/EB1B petitions, especially in a post-Kazarian world is incredible.

    2. Setting excellent contractual obligations and honoring them to the letter - They responded to most queries within 24 hours and all queries within 48 hours. All other contractual obligations of drafting documents in 10 business days were also honored. This is especially great given how many clients they have. It also suggests that they have a highly efficient system in place of routing/handling client queries - kudos to all the attorneys, paralegals and support staff!

    3. Understanding of science - This is perhaps the most important one. Our (my wife & I) previous experience of working with lawyers with regard to scientific documents (e.g. my wife's patent application) left a lot to be desired. However, the lawyers at NAmILG have an amazing grasp of scientific language across a wide range of disciplines. Thus, the recommendation & petition letters they draft are excellent and come across as written by a scientific professional. Some of my senior recommenders were also pleasantly surprised by this fact.

    I would like to thank Victoria Chen Immigration & Attorney Team for preparing my petition together with an excellent advice and support to collect the documents. Without them, it was not possible for me to get my case approval. Thank very much for helping me on my petition.
  • University of California Santa Barbara
    Postdoctoral Scholar

    It was a great experience working with Victoria Chen and her team at NAmILG. They had drafted an excellent petition letter and recommendation letters for me that was instrumental in my petition getting approved smoothly. All interactions with the team was very professional and my queries were answered within a 24 h time frame. I would highly recommend everyone to apply for their green cards through the Chen Associates. Given their expertise in this field, I decided to hire their service for my I-485 application as well. Thank you everybody at Chen Associates for your excellent work and support!
  • I am very glad for working with Chen Associates on my I-140 immigrant petition. The attorneys are so professional in their field of expertise. During the case preparation process, I had many questions about each step of the process and they patiently answered all of them ASAP. They were very responsible for accomplishing my case and they completed each step in the timelines and deadlines mentioned in their website. Due to their guides and expertise in case preparation, I have recently received approval of my I-140 petition. I strongly suggest working with Chen Associates (WeGreened.com).
  • It's been my great pleasure working with North America Immigration Law Group for my I-140 NIW, as well as my and my spouses's I-485 cases. They are very professional and diligent, so my green card preparation and filing went smoothly. Also, I feel like their system is very well organized and prepared. That's why I think our cases were approved without receiving RFE. I will definitely refer my friends to North America Immigration Law Group for their green card applications. Thanks!
  • Post Doctoral Research Associate

    Chen Associates worked on my I-140 NIW case. They were very fast. We submitted the case on August 19, 2016 and it was approved 1 month after. Even after approval, they found a typo on my approval notice and immediately applied for a "service request" and I got the corrected notice in 3 weeks. I absolutely recommend them for your NIW application.
  • University of Nevada Reno
    Postdoctoral Researcher

    Working with Chen Associates (wegreened.com) on my I-140 immigrant petition was a pleasure. Everything was so smooth, clear, rigorous and professional. But let me start from the beginning. Even before committing to retain their service they helpfully answered many questions that I had. When I was ready to start working with them, they provided me with the client packet, which is tremendously complete, clear and helpful. It guided me step-by-step in the process. Nonetheless, I had several doubts and questions, which were answered in an extremely timely manner and very professionally. On many occasions they answered my messages just a few hours after I had submitted them. There is no limit to the number and type of inquiries and they will always respond with clarity and timeliness. It took me about one month to have the first set of documents ready, and subsequent turnarounds were extremely quick. All the timelines and deadlines described in their website are accurate and were completely respected in my case. Perhaps most importantly, I always felt I was in great hands with Chen Associates. They are incredibly knowledgeable and made me feel comfortable at all times. I was sometimes stressed as going through the process of the permanent resident application can be stressful at times, but they were able to manage every aspect with an exceptional attention to details and this was stress-relieving and made me confident. They helped me to build a very strong case and indeed my immigrant petition in the category EB-2 NIW was approved in 40 days. Then, I decided to use their DIY kit for filing the I-485 and all I can say is that the kit is really complete and helpful just as the documentation for the I-140 is. The I-485 kit guided me throughout the process flawlessly. The honorary for their services is also very competitive, their success rate is impressive, and the "approval or refund" guarantee is a nice perk. I made my research before retaining them, I talked to a lot of friends and contacted at least 10 different attorneys. I am so glad that I chose Chen Associates.
