North America Immigration Law Group - WeGreened.com: The Leader in NIW & EB-1 Petitions, Backed by Data-Driven Strategies and 64,000+ Approvals
North America Immigration Law Group (Chen Immigration Law Associates – WeGreened®) is a U.S. immigration law firm dedicated to representing individuals, research institutions, and corporations across all 50 states in employment-based immigration matters, with a focus on I-140 immigrant petitions. We specialize exclusively in talent-based immigration categories and have a long-standing record of success in:
Choosing the Right Immigration Law Firm Matters More Than Ever
In the current immigration landscape, approval outcomes for NIW, EB-1, and O-1 petitions are increasingly shaped by shifting adjudication standards, heightened scrutiny, and evolving policy interpretations. Under these conditions, the law firm you work with is not simply a service provider. Rather, it becomes a critical strategic partner in assessing risk, framing evidence, and positioning your case effectively.
Many immigration law firms continue to rely on rigid internal policies, standardized support-letter requirements, or fixed drafting templates. While such approaches may simplify internal workflows, they often fail to account for how USCIS officers actually evaluate cases in practice, particularly in borderline, interdisciplinary, or non-traditional profiles.
At North America Immigration Law Group (Chen Immigration Law Associates), we take a fundamentally different, data-driven approach. Our strategy is informed by analysis of 64,000+ approved cases across NIW, EB-1, and O-1 categories, allowing us to identify adjudication patterns, evidentiary gaps, and effective framing strategies as standards evolve.
Rather than fitting cases into pre-set templates, we apply a customized drafting methodology that integrates historical approval data, current adjudication trends, and each client’s unique professional trajectory. This approach enables us to craft petitions that are not only well-written, but strategically aligned with how USCIS evaluates national interest, extraordinary ability, and sustained impact today.
64,000+ Approvals: Data-Informed Insight into USCIS Adjudication Trends
With 64,000+ approved cases across the EB-1A, EB-1B, EB-2 NIW, and O-1 categories, our work provides a unique, data-informed perspective on how USCIS evaluates employment-based immigration petitions in practice.
As adjudication standards continue to evolve, historical approval outcomes offer critical insight into how evidentiary thresholds, framing expectations, and discretionary analysis shift over time. By systematically analyzing patterns across thousands of successful cases, we are able to identify emerging trends and anticipate areas of heightened scrutiny.
At North America Immigration Law Group (Chen Immigration Law Associates), this depth of case data informs not only how petitions are drafted, but how strategies are adjusted in real time. This ensures that each case is positioned in alignment with current USCIS adjudication rather than static assumptions.

The "Anti-Template" Philosophy
We Draft for Today's USCIS, Not Yesterday's
U.S. immigration adjudication is inherently dynamic. Standards, evidentiary expectations, and areas of scrutiny evolve continuously, and arguments that were persuasive months ago may no longer be sufficient under current review practices. Because we file a high volume of employment-based petitions each year, we are able to identify shifts in USCIS adjudication at an early stage. These shifts may include increased scrutiny of specific fields, changes in how national importance is interpreted, or higher expectations for evidentiary specificity.
At North America Immigration Law Group (Chen Immigration Law Associates), our drafting process begins with an assessment of how cases are being adjudicated today, not how they were approved in the past. Rather than relying on static language or pre-set formats, each petition letter is developed through case-specific legal analysis to ensure that the client’s background is framed in alignment with current adjudication trends.
Why Customization Matters for "National Importance"
One of the most common grounds for NIW denial is a failure to clearly establish national importance. Broad or generalized assertions of importance, without precise linkage to U.S. priorities, are increasingly insufficient. Therefore, effective petitions must go beyond generic descriptions. Each case is framed to connect the client’s specific research, technical expertise, or business activities to concrete national needs, such as artificial intelligence leadership, public health advancement, or supply chain resilience.
Drawing on insights from recent approvals, we construct arguments that reflect how USCIS officers are currently evaluating national impact. These arguments rely on specific and technical examples rather than abstract or conclusory statements.
Tailored Argument Construction
Each case is evaluated as an integrated legal record, not simply as a collection of credentials. A dedicated attorney reviews the client’s publication record, funding history, professional trajectory, and real-world impact to develop a cohesive legal narrative tailored to the case. This from-scratch analytical approach allows us, in appropriate cases, to rely on the strength of the legal argument itself. By grounding the petition in detailed analysis and current adjudication standards, the case is positioned to stand on its own legal merits.
Proven Results in a Heightened Adjudication Climate
In the current immigration adjudication climate, where USCIS scrutiny has increased across employment-based categories, measurable outcomes matter. While many firms reference "high success rates" in general terms, few provide verifiable, case-volume–backed data that allows prospective clients to understand performance in context.
At North America Immigration Law Group (Chen Immigration Law Associates), we take a transparent, data-driven approach to evaluating outcomes. Under our Approval or Refund® service, between January 2012 and December 2025, the firm achieved an overall success rate of 98% across 52,753 cases.
This performance spans multiple employment-based immigrant visa categories:
- EB-2 NIW: 99% approval rate, based on 42,047 approvals
- EB-1A: 91% approval rate, based on 9,218 approvals
- EB-1B: 98% approval rate, based on 1,488 approvals
These results are particularly notable given the increasingly rigorous review standards applied by USCIS during this period, especially for industry-based NIW petitions where national importance and independent impact are closely examined.
Rather than relying on generalized claims, we publish detailed, verifiable approval data to provide clients with a clear understanding of what has been achieved in practice. This commitment to transparency reflects how we approach case strategy more broadly: with evidence, accountability, and a focus on outcomes that withstand heightened adjudication scrutiny.

Client Testimonials
I have to say the team at Chen Immigration Law Associates are very professional and responsive. My I-140 NIW EB-2 was approved recently and I truly appreciate all the patience and efforts that their team did for my case. As a result of this satisfactory experience, I am planning to continue working with Chen Immigration group for my I-485 case. Before applying for NIW, I searched many other lawyers and this firm was the best among them. Good luck everyone!- A. S., Teaching/Research Assistant
The Chen Immigration Law group was recommended to me by a fellow postdoc at a networking event. He claimed that if they say that my credentials are good enough to file a case for a green card then it is almost certain success. He was absolutely right.- P. F., Post-doctoral Scientist
After evaluating my credentials we decided to apply under the EB2-NIW category. Overall, it was a pleasure working with them. All my questions were answered promptly and to the point. Although the communication was only through emails, it was very effective. They made very clear to me what documents are necessary and how to obtain them and they drafted amazing reference letters and the I-140 petition letter. The price was very reasonable (the best I could find) and they always keep their timeline.
I am really grateful for their service and I highly recommend them. Thank you so much!
Chen Immigration is by far the most professional and meticulous group I have come across. The entire process, right from the evaluation by Victoria Chen, to the final submission to USCIS is systematic and diligently planned. Each and every question is answered and at no point does one feel helpless. The letters are expertly drafted. Kudos to the team and Ms. Chen.- S. P., Scientist
Thank You Chen Immigration and Attorneys for your tremendous effort on helping me approve my NIW EB-2 petition. They are very professional from start to end. All the questions asked were answered in a professional manner in timely basis. I really appreciate all your work and suggestion during the process. If anyone of you plan to file your NIWS, Chen Immigration and Attorneys are probably the best options out there.- M. K., Geophysicist
My EB1A was approved four days after USCIS received my documents. I'm very impressed by the professionalism and enthusiasm of NAmILG during preparation and filing of my case. The prompt approval of my case wouldn't be possible without the expertise and hard working of the attorneys of NAmILG.- T. W., Postdoc
One of the advantages of NAmILG I want to point out is they drafted all of the required letters, which saved huge amount of time for me. I'll definitely recommend to my friends who are looking for immigration attorneys.
