Client’s Testimonial:
“Thank you so much for your effort in preparing my I-140 case, even after the initial denial and throughout the appeal process. I truly appreciate your dedication and am very grateful that the case was ultimately approved.”
On April 10th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Product Development Engineer in the Field of Environmental Engineering (Approval Notice).
General Field: Environmental Engineering
Position at the Time of Case Filing: Product Development Engineer
Country of Origin: Taiwan
State of Residence at the Time of Filing: Texas
Approval Notice Date: April 10th, 2026
Processing Time: 3 months, 22 days
Case Summary:
Our firm is pleased to share that a refiled EB-2 NIW (National Interest Waiver) petition has been approved for an engineer in environmental engineering, specializing in physical-chemical separation technologies, electrosorption, and critical mineral recovery from industrial brines and wastewater. After an initial filing, our expert team strategically refiled the petition with a stronger, more compelling case, and we are proud to celebrate this well-deserved approval in under 4 months.
Client Background and Proposed Endeavor
Holding a Ph.D. in environmental engineering, this researcher brings deep expertise in electrochemical water treatment, thermodynamic modeling, and mineral scale prediction under high-temperature, high-pressure conditions. The client is currently employed as a product development engineer, applying this expertise directly in industry. The proposed endeavor is to continue developing and scaling up innovative physical-chemical separation technologies for the selective recovery of critical and valuable metals from industrial brines and wastewater, thereby supporting sustainable materials management, mitigating environmental impacts, and strengthening the resilience of domestic supply chains.
National Significance of the Research
We emphasized that this research carries significant importance and far-reaching implications for the United States. The client's work on recovering critical minerals from industrial waste streams directly supports key federal initiatives prioritizing novel approaches to establishing a circular economy and reducing U.S. dependence on foreign sources for minerals essential to clean energy and next-generation technologies. The client's proposed endeavor also falls within formally recognized critical and emerging technology areas, including clean, sustainable, and smart manufacturing and energy-efficiency technologies, underscoring its strategic importance to U.S. technological leadership and national security.
Impressive Credentials and Achievements
To further strengthen the case, we highlighted exceptional credentials:
- Publications: An impressive portfolio of 7 peer-reviewed journal articles (3 of them first-authored), 16 peer-reviewed conference articles (4 of them first-authored), and 3 first-authored conference abstracts.
- Citations: The published body of work has been cited 218 times.
- Peer Review Service: At least 10 peer reviews completed for distinguished journals.
Expert Validation
To further corroborate the objective evidence, 4 expert recommendation letters were submitted. One recommender noted:
"In conclusion, [Client]'s research is highly significant, particularly for its impact on scale formation, benefitting various industries and the United States as a whole."
Case Outcome
This researcher's pioneering contributions to electrochemical water treatment, critical mineral recovery, and sustainable resource management position them to make meaningful and lasting contributions to U.S. clean energy infrastructure and environmental resilience for years to come. We are honored to have supported this journey and extend our sincere best wishes for continued success in both research and career pursuits.
