On August 2nd, 2023, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Researcher in the Field of Heterogeneous Catalysis (Approval Notice).
General Field: Heterogeneous Catalysis
Position at the Time of Case Filing: Postdoctoral Researcher
Country of Origin: Vietnam
State of Residence at the Time of Filing: South Korea
Approval Notice Date: August 2nd, 2023
Processing Time: 5 days (Premium Processing Requested)
Case Summary:
We were retained to represent a Vietnamese postdoctoral researcher based in South Korea in filing his I-140 National Interest Waiver (NIW) petition. His research focuses on developing novel catalytic and ammonia decomposition and production processes for low-carbon hydrogen production and efficient hydrogen storage, contributing to energy sustainability and climate change mitigation.
A key part of our role was to establish that his Ph.D. in energy chemical engineering and significant accomplishments qualify him as a member of the professions with advanced degrees. Additionally, we demonstrated that his ongoing research is critical to maintaining and advancing U.S. technological leadership.
To build a compelling case, we carefully compiled a strong petition package that highlighted:
-
- The importance of his research, which directly addresses critical challenges in climate change mitigation and hydrogen energy. His advancements in hydrogen production and storage help reduce greenhouse gas emissions and support clean energy technologies.
- His contributions to biofuel production align with global efforts toward sustainable energy. His methodologies improve hydrogen production efficiency, strengthening U.S. energy security and leadership in renewable energy.
We also emphasized his exceptional track record and impact in the field. His research has led to 15 peer-reviewed journal articles (14 as first author) and 1 patent, published in five of the top journals in his field. His 783 citations reflect the significant influence of his work on the scientific community.
Additionally, we demonstrated his recognition as an expert in heterogeneous catalysis by highlighting his role as a peer reviewer for a leading journal. To date, he has completed at least 29 reviews, proving his expertise and credibility in his area of research.
Furthermore, we underscored that his research has been funded by the National Research Foundation of Korea (NRFK), which supports projects that advance knowledge and improve the quality of life. This funding affirms the significance of his work in enhancing energy sustainability and combating climate change.
Finally, we also demonstrated our client’s credibility and significant contributions by including two letters from experts in the field, who attested to the impact and advancement of his research.
We are pleased to share that our client has a proven record of impactful research in a field crucial to U.S. national interests. Even if there were qualified American workers in this area, his expertise and contributions remain highly valuable. Just 5 days after submission, USCIS approved his NIW petition, recognizing his experience, leadership, and expertise. The North America Immigration Law Group sincerely appreciates our client’s trust in our team, and we wish him continued success in his career.
