Success Stories After RFE: 9 Approvals on April 13, 2026

wegreened — Tue, 14 Apr 2026 06:40:32 GMT

A Request for Evidence, or RFE, is not a final adjudication outcome. In the employment-based visa context, it typically reflects the adjudicating officer’s need for a clearer explanation of eligibility, a stronger evidentiary connection between the applicant’s record and the governing legal standard, or a more persuasive articulation of the applicant’s proposed work and future role. Even when approval is ultimately secured, an RFE marks a more demanding stage of review in which the petition must remain coherent and persuasive under closer scrutiny.

The following nine success stories highlight approvals secured after RFE review, including two EB-1A approvals, five NIW approvals, and two O-1A approvals. These cases reflect a range of adjudicative complexities, including refilings after earlier denials, cross-service-center transfers, variation in academic and professional backgrounds, and differing evidentiary strategies.

Cases With Inherent Challenges

Refiled Petitions After Prior Denials

Several approvals in this group did not follow a straightforward path to success. Two EB-1A cases and one NIW case were refiled after earlier petitions had received RFEs and were ultimately denied. These circumstances introduce an added layer of difficulty because the subsequent filing must not only meet the eligibility standard but also overcome concerns raised in prior adjudications.

Cross-Service-Center Adjudication

Some cases involved procedural movement across multiple service centers. Two NIW petitions were transferred from the Nebraska Service Center to the Texas Service Center and then returned to the Nebraska Service Center before approval. This kind of adjudicative path requires the petition to remain internally consistent and persuasive across different reviewing environments.

Variation in Academic and Professional Profiles

The approved cases reflect a wide range of professional contexts, from graduate students and research fellows to senior industry leaders. Academic credentials ranged from master’s degrees to Ph.D. and M.D. qualifications, and the scholarly records varied significantly in publication count and citation impact. This diversity demonstrates that approval after RFE review does not depend on a single benchmark.

Differences in Evidentiary Support

The cases also show notable variation in evidentiary strategies. Some petitions were supported by multiple recommendation and testimonial letters, while others proceeded without any supporting letters at all. This spread underscores that post-RFE approval can be achieved through different forms of evidentiary presentation, provided the overall petition remains persuasive.

Success Story: Building Lighter, Stronger Aerospace Structures With Self-Monitoring Capability, NIW Approved For an Indian Assistant Professor

wegreened — Mon, 13 Apr 2026 09:00:25 GMT

On February 4^th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Tenure-Track Assistant Professor in the Field of Aerospace Engineering (Approval Notice).

General Field: Aerospace Engineering

Position at the Time of Case Filing: Tenure-Track Assistant Professor

Country of Origin: India

State of Residence at the Time of Filing: Mississippi

Approval Notice Date: February 4^th, 2026

Processing Time: 4 months, 20 days (Premium Processing Requested)

Case Summary:

The client in this NIW case built a focused record in aerospace engineering centered on developing smart, high-performance composite materials and structures using adaptive experimental techniques and non-destructive evaluation methods. North America Immigration Law Group (Chen Immigration Law Associates) presented the petition around that practical engineering impact, showing how the client’s work advances material performance not only for aerospace applications but also for adjacent sectors such as electronics, automotive components, and advanced packaging, where durability and thermal stability are critical.

With a Ph.D. in aerospace engineering, the client established a research profile grounded in experimental mechanics, composite materials, and structural health monitoring. The client’s influence was reflected in objective evidence of independent reliance. The record documented 7 first-authored peer-reviewed journal articles, 6 peer-reviewed conference papers (including 4 first-authored), and 4 first-authored book chapters, with the published body of work cited 71 times.

Peer recognition extended beyond authorship. The client has completed at least 27 peer reviews, which we framed as sustained peer trust in his technical judgment and subject-matter expertise. Invitations to review in this area reflect that editors and conference organizers rely on the client to evaluate cutting-edge work in aerospace materials and structural systems, reinforcing his standing as an independent contributor within the field.

The case also included objective support tied directly to national priorities. The client’s research has received funding from NASA, which we presented as external validation that his work aligns with U.S. interests in advancing aerospace technology, structural reliability, and materials innovation critical to exploration and national security.

Independent expert testimony captured the broader relevance of these contributions in applied terms:

“His work advances the performance of plastic materials for use in electronics, automotive components, and packaging, where strength, reliability, and thermal stability are essential.”

With the evidence organized around original material and structural contributions, independent reliance, and sustained peer trust, the NIW petition was approved. NAILG was honored to assist in presenting a clear, adjudicator-focused record demonstrating why waiving the labor certification requirement served the national interest in this case.

Success Stories After RFE: 5 Approvals on April 10, 2026

wegreened — Mon, 13 Apr 2026 07:12:37 GMT

A Request for Evidence, or RFE, is not a final adjudication outcome. In the employment-based visa context, it often reflects the adjudicating officer’s need for a clearer explanation of eligibility, a stronger evidentiary connection between the applicant’s record and the governing legal standard, or a more persuasive account of the applicant’s proposed work and future role. Even when approval is ultimately secured, an RFE usually marks a more demanding stage of review in which the petition must remain coherent and persuasive under closer scrutiny.

The following success stories highlight five approvals secured after RFE review, consisting of four NIW cases and one O-1A case. These cases reflect various forms of adjudicative complexity, ranging from multi-center transfers to approvals for candidates in non-STEM fields.

Cases With Inherent Challenges

Cross-Service-Center Transfers and Procedural Complexity

Several of the approved matters involved significant procedural movement between service centers. Three petitions were initially filed with the Nebraska Service Center, transferred to the Texas Service Center, and eventually returned to the Nebraska Service Center before securing final approval. Maintaining internal consistency across these transfers adds a layer of difficulty, as the record must remain persuasive even when moving between different adjudicative environments.

Diversity in Professional Fields and Academic Backgrounds

The approvals demonstrate that success under RFE review is possible across widely different disciplines, including Autonomous Systems, Corporate Governance, and Blockchain Technology. Notably, while most cases involved STEM backgrounds, several approvals were secured for applicants in non-STEM fields. This shows that the national interest can be persuasively argued beyond traditional scientific research.

Different Premium Processing Paths

These approvals also did not follow one premium processing pattern. Three petitions moved forward with upfront premium processing, while the other two proceeded through premium processing upgrades. That variation is notable because it reflects different filing strategies and adjudicative timelines, yet all five petitions still secured approval after a more demanding review stage.

Wide Variation in Scholarly and Letter Support

Within the four NIW cases, the applicants presented scholarly records ranging from 4 to 7 publications and from 20 to 76 citations, with the latest peer-reviewed work dating from 2023 to 2025. Their evidentiary support also varied considerably, from filings with no recommendation or testimonial letters at all to matters supported by multiple recommendation letters and testimonial letters. That spread is important because it shows these approvals did not turn on a single publication count, citation level, or letter strategy.

WeGreened Approval Statistics: Week of March 30, 2026

wegreened — Mon, 13 Apr 2026 03:30:03 GMT

During the week of March 30 to April 5, 2026, WeGreened received 126 approval notices from U.S. Citizenship and Immigration Services (USCIS). Of the 126 approvals, 115 were for NIW (National Interest Waiver), 9 were for EB1A (Alien of Extraordinary Ability), 1 was for EB1B (Outstanding Professors or Researchers), and 1 was for O1A (Individuals with Extraordinary Ability or Achievement).

NIW again represented the majority of approvals, while EB1A remained a smaller but steady share of the week’s results.

EB1A and NIW Credential Analysis

EB1A petitioners this week showed a relatively concentrated profile, although one extremely high-citation case widened the upper end of the range. Publications ranged from 3 to 64 (Q1: 13, median: 20, Q3: 31), and citations ranged from 442 to 43,467 (Q1: 849, median: 1,113, Q3: 2,887). Even with that outlier, the category still leaned toward stronger traditional records, especially where the evidence could support a broader final-merits narrative of sustained recognition.

NIW petitioners again reflected a much broader spectrum of credential profiles. Publications ranged from 1 to 85 (Q1: 6, median: 8, Q3: 14), and citations ranged from 0 to 7,547 (Q1: 60, median: 142, Q3: 261). Compared with EB1A, NIW again showed a wider spread across both publications and citations, reinforcing that approvals can include earlier-stage, mixed-path, and lower-metric profiles when the petition clearly defines a nationally important endeavor, shows credible forward momentum, and explains why waiver flexibility benefits the United States.

Insights on Petitioner Backgrounds and Fields

EB1A approvals this week were distributed across life sciences, AI/computing, engineering, public-health-related work, and one economics case. Employment backgrounds were mixed, including research staff, faculty, industry professionals, and one student/candidate profile. EB1A also remained entirely STEM-designated, with a Ph.D.-heavy degree mix of 7 Ph.D. holders and 2 master’s-level petitioners.

NIW approvals were broader across both field and career stage. Life sciences, AI/computing/data-facing work, and engineering made up the largest field groupings, with additional representation in biomedical and health-related work, math/physical sciences, and social science/education. NIW remained heavily STEM-weighted, with 94 STEM and 21 non-STEM approvals, and showed a wider degree mix of 69 Ph.D. holders, 30 master’s-level petitioners, 14 professional doctorates, and 2 no-advanced-degree cases.

Highlighted NIW Case: Approval at the Zero-Citation Stage for a Cybersecurity Researcher

One of this week’s more revealing NIW approvals involved a cybersecurity case with only 3 publications and 0 citations at filing. The proposed endeavor focused on AI-driven threat detection, malware analysis, and the protection of healthcare-connected systems, especially where cybersecurity failures can affect critical medical infrastructure. Despite the modest metrics, the case was approved, showing again that NIW viability does not depend on citation volume alone.

What strengthened the filing was a focused Dhanasar presentation. The petition defined the endeavor with enough specificity to show clear national relevance, tying the work to healthcare cybersecurity risks, patient safety, and broader U.S. digital-security priorities. For the “well positioned” prong, the case relied less on citation-based impact and more on technical training, peer-reviewed publications, concrete work in cybersecurity and machine learning, expert support letters, and a credible future plan. On balance, the filing also explained why flexibility beyond a single employer or labor-certification framework would better support continued contributions in a fast-moving field. The case is a useful example of how a lower-metric NIW can still succeed when the legal framing is tight and the evidence is organized around substance rather than numbers.

Adjudication Trends and Policy Observations

This week’s approvals again highlight the wider range of approvable profiles under NIW compared with EB1A. EB1A remained more concentrated in stronger conventional records, while NIW continued to include both established and lower-metric cases.

The highlighted approval is especially useful in that context. It suggests that this week’s NIW outcomes were shaped less by raw publication or citation counts than by whether the petition clearly defined the endeavor, supported future potential with concrete evidence, and made a persuasive waiver argument. The broader pattern remains the same: approval trends continue to favor cases where legal theory, evidence, and field-specific context are closely aligned.

Case Summary:

In the fast-evolving area of biomedical diagnostics, the client, an expert in chemical engineering with an M.S. in chemical engineering, is advancing research that bridges engineering, biology, and data-driven analysis to improve how diseases are detected and monitored. With the support of North America Immigration Law Group (NAILG), the client’s I-140 EB-2 NIW (National Interest Waiver) petition was strategically prepared and ultimately approved, reflecting the strength of the proposed endeavor and the clarity of the evidentiary record.

Transforming Disease Diagnosis Through Label-Free Blood and Cell Analysis

The client’s proposed endeavor is to develop and implement an advanced blood and cell analysis device that enables rapid, label-free characterization of magnetic properties in biological cells. The petition framed this work as an effort to revolutionize disease diagnosis and monitoring across hematological disorders, anemia, and cancer.

To present the endeavor in adjudicator-friendly terms, we emphasized the real-world value of faster, more informative, and less invasive cell analysis capabilities. We explained how improving cell-level characterization can strengthen diagnostic workflows, support earlier detection, and enable more precise monitoring of treatment response, especially for conditions where timely and accurate measurements are critical to patient care. We also highlighted that the endeavor has broad potential impact because it is designed to support multiple high-burden disease areas rather than a narrow, single-use application.

Establishing a Record of Research Excellence

To demonstrate that the client is well positioned to advance the proposed endeavor, we emphasized objective evidence of research productivity and independent recognition. At the time of filing, the client had authored 6 peer-reviewed journal articles, including 4 co-first-authored or first-authored publications, along with 4 conference abstracts, including 2 first-authored abstracts. The client’s publications had been cited a total of 53 times.

We did not present these metrics as automatically sufficient. Instead, we explained how an adjudicator could reasonably interpret the citation record as evidence that independent researchers are relying on the client’s findings to inform and support their own work. We also provided additional context showing that at least two of the client’s papers ranked among the most highly cited works in their broader field for their publication years, including one paper in the top 1% and another in the top 10%. This helped translate the citation record into clearer evidence of influence by showing that the client’s work performed strongly relative to other research published in the same timeframe.

The petition also documented that the client has completed at least 2 peer reviews. We positioned peer-review invitations as an additional indicator of recognition, since reputable venues typically select reviewers who have demonstrated expertise and sound judgment to evaluate the work of other researchers.

Expert Endorsements

The petition included 4 letters of recommendation from experts in the field. These letters supported the case by translating technical contributions into clear significance, explaining why the client’s research approaches are considered novel and useful, and corroborating the objective record of publications, citations, and research activity.

“As a highly gifted researcher in chemical engineering, with her strong scientific productivity and a strong publication record, it is clear to me that [Client’s] research in the U.S. merits supportive consideration.”

A Successful Outcome

USCIS approved the client’s NIW petition, reflecting a well-supported presentation of the endeavor’s substantial merit and national importance and the client’s strong positioning to advance it. We are proud to have guided this client to a successful outcome and look forward to the client’s continued contributions to improving diagnostic and monitoring capabilities for serious hematological and cancer-related conditions in the United States.

Position at the Time of Case Filing: Senior Formulation Scientist

Country of Origin: Jordan

State of Residence at the Time of Filing: Missouri

Approval Notice Date: February 17^th, 2026

Processing Time: 24 months, 15 days

Case Summary:

Medication adherence is often treated as a patient-behavior problem, but in many therapies, the real leverage lies upstream in formulation: whether an oral dosage form can deliver the right amount of drug, at the right time, with tolerable side effects. Our client, a pharmaceutical sciences researcher with a Ph.D. in Pharmaceutics, built a focused record around that practical challenge, creating and improving oral dosage forms designed to ensure precise administration of therapeutic agents to increase adherence, reduce side effects, and improve patient outcomes.

North America Immigration Law Group (Chen Immigration Law Associates) framed the endeavor as a public-health and system-efficiency story. The petition emphasized that better oral delivery is a mechanism for reducing avoidable complications and improving therapeutic effectiveness at the population scale, especially in areas where treatment success depends on consistent dosing and tolerability.

The record was particularly persuasive because the client’s work was already recognized as essential research within the field. The case documented 8 peer-reviewed journal articles (including 2 first-authored), 1 peer-reviewed conference paper, 1 abstract, and 1 book chapter, with 96 citations. NAILG translated these statistics into a straightforward adjudicator-facing point: independent researchers have repeatedly used her work to support their own investigations across topics tied to pharmaceutical delivery and clinically relevant applications, signaling independent reliance rather than isolated publication.

Peer trust strengthened the case. The client completed at least 21 reviews, including repeated invitations to review for major professional conference venues, which the case framed as evidence that organizers and editors relied on her judgment to evaluate other researchers’ work in oral medications and related technologies.

NAILG organized the petition around a clear theme: a researcher with the training to build precise oral dosage forms, a track record of peer-validated output that others cite and build upon, and sustained peer trust reflected in substantial reviewing activity, all aligned to an endeavor that improves adherence and outcomes through better drug delivery.

Success Stories After RFE: 2 I-140 Approvals on April 9, 2026

wegreened — Fri, 10 Apr 2026 06:12:07 GMT

A Request for Evidence, or RFE, is not a final adjudication outcome. In the I-140 context, it often reflects the adjudicating officer’s need for a clearer explanation of eligibility, a stronger evidentiary connection between the applicant’s record and the governing legal standard, or a more persuasive account of the applicant’s proposed work and future role. Even when approval is ultimately secured, an RFE usually marks a more demanding stage of review in which the petition must remain coherent and persuasive under closer scrutiny.

The following success stories highlight two NIW approvals secured after RFE review. Taken together, these matters reflect different forms of adjudicative complexity, including one case that moved between service centers before returning to its original service center. They also show variation in scholarly profile and proposed work that remained aligned with each applicant’s current professional role.

Cases With Inherent Challenges

Cross-Service-Center Adjudication

One of the approved NIW matters did not remain on a single adjudicative track. It moved from the Nebraska Service Center to the Texas Service Center and then back to the Nebraska Service Center before approval. That kind of procedural movement can add complexity because the petition must remain internally consistent and persuasive across multiple stages of review.

Different Premium Processing Paths

These approved matters also followed different premium processing paths rather than a single procedural pattern. One petition proceeded with upfront premium processing, while the other moved forward through a premium processing upgrade. That distinction is notable because it reflects different adjudicative timelines and filing strategies, while both petitions still ultimately secured approval after heightened review.

Varied Scholarly Records Under RFE Review

These approvals also reflect different kinds of scholarly presentations. One applicant presented 8 publications and 194 citations, with recent peer-reviewed work dating to 2025, while the other moved forward with 9 publications and 46 citations, with the latest peer-reviewed publication dating to 2023. That variation is important because it shows that post-RFE approval did not turn on a single publication or citation pattern.

Client’s Testimonial:

“I had a wonderful experience working with the lawyers at Chen Immigration (wegreened) for my EB-2 NIW petition. From the very beginning, they were incredibly helpful, detailed, and meticulous about making sure my profile and materials were represented in the strongest possible way. They gave clear guidance, thoughtful feedback, and the kind of strategic suggestions that genuinely made me feel like my case was in great hands.

One thing I really appreciated was how seamless their system is. Their website is super user-friendly, organized, and easy to follow, which made the whole process feel much less overwhelming. I was honestly very nervous going into this, but their communication style and the way they handled each step put me completely at ease.

Timeline-wise, I started with regular processing in early November and upgraded to premium processing around Thanksgiving. I received my approval decision in 15 business days. I am so grateful for their support and professionalism, and I would absolutely recommend Chen Immigration to anyone considering an NIW petition.”

On December 19^th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Graduate Research Assistant in the Field of Petroleum Engineering (Approval Notice).

General Field: Petroleum Engineering

Position at the Time of Case Filing: Graduate Research Assistant

Country of Origin: Nigeria

State of Residence at the Time of Filing: Oklahoma

Approval Notice Date: December 19^th, 2025

Processing Time: 1 month, 14 days (Premium Processing Upgrade Requested)

Case Summary:

A central challenge in modern petroleum engineering is how to increase recovery from mature reservoirs while also reducing emissions, minimizing waste, and enabling more reliable carbon dioxide storage. The client’s work addresses this critical intersection, combining advanced reservoir modeling with data-driven analytics and machine learning to improve forecasting, simulation, and enhanced oil recovery workflows that support both production efficiency and environmental sustainability.

North America Immigration Law Group (Chen Immigration Law Associates) built the NIW filing around a practical logic that USCIS can verify: the endeavor matters because it strengthens U.S. energy independence while improving operational efficiency and carbon management, and the client is well-positioned because the work already shows measurable technical performance and independent uptake.

Instead of framing the work as a collection of unrelated studies, the petition presented a cohesive research direction. The client is developing a user-friendly interface that integrates simulation outputs with machine learning models to run sensitivity analyses on reservoir and operational parameters that influence long term carbon dioxide containment. In parallel, the client is building predictive models and optimization workflows for water alternating gas injection, using field data and simulation results to improve recovery while reducing gas use and operational costs in mature reservoirs. The client is currently conducting this research in an academic research setting in the United States.

For NIW, the most persuasive cases tend to read less like a résumé and more like a pattern of external validation. We therefore anchored the presentation in objective indicators and then explained why each matters to adjudicators, rather than treating the numbers as self-proving:

Publication record: 2 peer-reviewed journal articles (including 1 first-authored) and 1 peer-reviewed conference article
Citation reliance: 13 citations total, including one article with a notably high citation rate for its field and year, supporting the argument that other researchers are using the work as a reference point rather than treating it as routine output
Peer review trust: documented reviewer service for a major journal, reinforcing that the community views the client as technically credible enough to evaluate others’ work

These metrics were not offered as automatic proof. We tied them to the way the field operates: selective publication indicates success under peer scrutiny, citations reflect independent reliance, and reviewer invitations function as signals of professional trust.

The NIW filing also included two letters from established experts to connect the technical work to its broader relevance. Strategically, these letters were used to confirm that the client’s research direction addresses real operational and national priorities, and that the client’s methods are already being recognized as useful by others in the field.

“To summarize this letter, [Client] is a vital member of the petroleum engineering research community. Given the need for accurate CO₂ emission prediction, reliable fuel cost estimation, and enhanced tools that support U.S. clean energy goals, it is clear that there is a need for further improvement with respect to these issues. As [Client] has produced valuable research in this regard, there is an ongoing demand for her particular expertise.”

USCIS approved the I-140 EB-2 National Interest Waiver petition. This outcome reflects a case strategy that emphasized substantial merit and national importance, a credible showing that the client is well-positioned through documented research outputs and independent reliance, and a clear explanation of why waiving labor certification would help the United States benefit from this work without unnecessary delay.
