Success Story: Our Firm Helped a Bangladeshi Contaminant Hydrogeology Researcher Secure NIW Approval Without an RFE.
Client’s Testimonial:
"I had a great experience working with Chen on my case. They were always responsive to my questions, whether big or small, and diligently incorporated my responses into the preparation of the case materials. They were also very thorough in reviewing and preparing my documents. Overall, they handled my case with great care and attention, and were open and cooperative whenever I had suggestions. I would highly recommend this firm to anyone considering an EB-2 NIW application.”
On April 20th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Quantitative Hydrogeologist in the Field of Contaminant Hydrogeology (Approval Notice).
General Field: Contaminant Hydrogeology
Position at the Time of Case Filing: Quantitative Hydrogeologist
Country of Origin: Bangladesh
State of Residence at the Time of Filing: Washington
Approval Notice Date: April 20th, 2026
Processing Time: 4 months, 2 days (Premium Processing Upgrade Requested)
Case Summary:
The client, Ph.D. in Geosciences, received I-140 NIW approval for work in contaminant hydrogeology. The petition presented the client’s proposed endeavor as research focused on characterizing and predicting contaminant transport mechanisms in soil and groundwater through hydrogeologic analyses and computational modeling. We explained that this work supports effective mitigation strategies to reduce the long-term effects of pollution on water resources and public health, making it a strong fit for the NIW framework.
The client’s record included 4 peer-reviewed journal articles, including 2 first-authored articles, and 9 abstracts, including 5 first-authored abstracts. Since the citation count was still developing, the petition did not overstate the raw number. Instead, it explained the significance of the work through context. The client’s published body of work had received 7 citations, and one first-authored article was already among the top 20% most cited articles in Geosciences for its publication year. This helped show that the client’s research was gaining early independent reliance in a specialized field.
We also demonstrated the significance through the substance of the client’s contributions. The petition highlighted work showing how flooding can mobilize uranium and sulfate from the vadose zone into groundwater, how tracer data can separate transport processes, and how soil properties influence salt accumulation and release. These findings were tied to practical cleanup and mitigation planning, especially for contaminated sites where accurate prediction of pollutant movement is essential. Evidence of National Science Foundation funding further supported the national importance of the client’s research.
The client’s peer review record also strengthened the case. The client had completed at least 3 reviews for a journal in the field, which helped show that editors recognized the client’s expertise and trusted the client to evaluate related scientific work. In a developing but highly specialized record, this evidence helped support the broader argument that the client was well-positioned to continue advancing contaminant hydrogeology research.
Overall, this approval reflects a case strategy that carefully contextualized a focused publication and citation record. Rather than relying on volume alone, the petition showed how the client’s research addressed water safety, environmental cleanup, public health, and U.S. remediation priorities. We are delighted that the client’s I-140 NIW petition was approved and wish the client continued success in the United States.
