Success Story: NAILG Addresses National Importance and Well-Positioned Concerns to Secure NIW Approval for a Process Engineer in Bioprocess Engineering
Client’s Testimonial:
"I’m very grateful to Chen Immigration Attorneys for their professional support throughout my NIW case, especially during the RFE stage. The team carefully addressed USCIS’s concerns, helped organize the supporting evidence, and clearly presented the importance and impact of my research. Their guidance made the process much more manageable, and I’m very happy with the successful approval of my I-140.”
On August 19th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Process Engineer in the Field of Bioprocess Engineering (Approval Notice).

Processing Time: 17 months, 13 days (Premium Processing Requested)
Case Summary:
An NIW petition may face additional scrutiny even when the applicant has a strong academic and research background. This was the situation for our client, a process engineer in the field of bioprocess engineering whose petition was filed on March 6th, 2025. The client sought to advance more efficient methods for converting biomass and other renewable resources into sustainable fuels and materials, with broader applications in reducing resource consumption and supporting more sustainable industrial production. At the time of filing, the client held a Ph.D. in bioprocess engineering and had established a research record addressing biomass processing and renewable material production.
The client upgraded to premium processing on March 16th, 2026. USCIS issued a Request for Evidence (RFE) on May 14th, 2026. Although USCIS acknowledged the substantial merit of the client's work, the RFE questioned its national importance and whether the client was sufficiently well positioned to advance it. One issue was USCIS's characterization of the client's research objectives as resembling ordinary occupational duties rather than a distinct research endeavor. North America Immigration Law Group (Chen Immigration Law Associates) therefore structured the response to clarify the distinction between the client's employment and the broader scientific objectives of the endeavor. We explained how improvements in biomass conversion could contribute to renewable fuel and material production, reduced dependence on fossil resources, more efficient use of agricultural and forestry byproducts, and broader economic activity associated with sustainable manufacturing.
A substantial portion of the RFE response then addressed the client's positioning by placing the scholarly record in context rather than relying on raw numbers alone. The original petition documented 7 peer-reviewed journal articles, 2 peer-reviewed conference articles, 9 conference abstracts, 43 citations, and funding from the National Science Foundation and the Advanced Research Projects Agency-Energy. By the RFE response, the citation count had increased to 291, including 189 independent citations.
Rather than allowing these metrics to stand alone, our response demonstrated what the scholarly attention represented. We supplied examples showing independent researchers using the client's findings to interpret material performance, develop sustainable packaging materials, and evaluate renewable alternatives to petroleum-derived materials. We also revisited the 4 recommendation letters submitted with the original petition and explained how their detailed assessments were consistent with the objective record of the client's research influence. The response further strengthened the record with evidence of peer recognition and an updated plan describing how the client intended to continue research and development related to biomass processing, conversion, and scale-up while working professionally as a process engineer.
Taken together, the RFE response reframed the case around the full evidentiary record: the national implications of the client's research direction, documented independent use of the client's work, comparative evidence of scholarly influence, expert testimony, professional recognition, and concrete plans for continued work. The approval demonstrates the importance of responding to an RFE not simply by adding evidence, but by directly connecting each piece of evidence to the specific concerns raised during adjudication.
