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 heard about this law firm from one of my friends who had high recommendation. Before approaching Chen Immigration Law Associates, I had personally talked to an immigration lawyer whose fee was expensive and the lawyer did not seem much positive regarding my EB2-NIW case. When I first contacted Chen Immigration Law Associates for free EB2-NIW evaluation and heard that my case is eligible for approval or refund, it energized me and made me believe that my case is strong enough too. Though communication was only through email, it was easy and reliable. The timeline set in the contract is always fulfilled. I am really happy that I chose this law firm and I highly recommend it to anyone seeking immigration advice and services. Once again, I am very thankful to the team of Chen Immigration Law Associates for all their effort in making my petition a success.- O. P.
My I-140 (NIW) was approved this week!- M. R., Physician
I was fortunate to come across Chen immigration when I started looking into my options for green card. I quickly realized they are extremely professional and would handle my case at a personal level. Indeed, over the last 1 year they have performed beyond my expectations.
Chen immigration team gave me a free evaluation after assessing my portfolio. Their timing for my case has been impeccable at every step. The lawyers have worked with me as a team. Communication with the whole firm has just been outstanding. I would recommend Chen Immigration extremely highly to all my friends and anyone who is in my shoes and looking into the process for Green card.
I highly appreciate the support and professionalism of Chen Immigration Law firm. Although it took me a long time to gather all my documents but attorneys from WeGreened.com were never late in replying to any of my concerns. They were extremely meticulous in analyzing my documents and made sure all my supporting exhibits were appropriate. In only 30-days my EB2/NIW was approved and I'm sure it was due to their experience handling of my case. I'll certainly recommend others to consider hiring Chen Immigration Law Assoc. for any kind of immigration purposes. One of my friends is already in touch with them after hearing my success story. I sincerely appreciate their time and effort in preparing my case.- A. R., Postdoctoral Scholar
I'm very happy with all the work and advice Chen Immigration Team have put into my NIW application. The responses were always timely, the letters drafted were polite, well-structured and timely. When I got my RFE, I was worried, but with the help of the attorneys working with me, the answer to the RFE lead to approval.- M, Postpoc
Not only do the members of the team work extremely hard and with highest professionalism, they also show that they believe in their clients, are able to emphasize all the achievements better than I ever could, and they genuinely care.
Thank you so very much!
I cannot be happier with everything you've done for me!
I had a great experience working with Chen Immigration Law Group. I applied for EB1A premium processing and the case was approved within 2 weeks without any RFE.- P. J., Postdoctoral Researcher
I was impressed with the quality of petition letter and the reference letters drafted by their team. Although my field is highly technical, the attorneys seemed highly knowledgeable and were able to present my research in a manner which was easy to understand, impressive and yet not 'over-selling'.
They went over my research/citations meticulously and were able to catch mistakes which honestly I would have missed if I was preparing my own case. They were also very prompt with replying to any questions I had during the process.
In short, I would strongly recommend them to all who want to get through the green card process without stress.
