Success Stories: Chinese Senior Research Scientist Secures NIW and EB1B Approvals for Tissue Engineering and Bioadhesive Device Research
Client’s Testimonial:
“Thank you so much for this wonderful news! I would like to thank my attorney and the WeGreened team for your professionalism and dedication to the case preparation. It has been a smooth and pleasant experience working with you!”
On November 3rd, 2023, and January 29th, 2025, we received another EB-2 NIW (National Interest Waiver) and EB1B (Outstanding Researcher/Professor) approvals for a Senior Research Scientist in the field of Mechanical Engineering (Approval Notice).
General Field: Mechanical Engineering
Position at the Time of Case Filing: Senior Research Scientist
Country of Origin: China
State of Residence at the Time of Filing: Massachusetts
Approval Notice Date: November 3rd, 2023 (NIW); January 29th, 2025 (EB1B)
Processing Time: 11 days (NIW); 12 days (EB1B, Premium Processing Requested)
Case Summary:
We are pleased to share the successful NIW and EB1B approvals of a senior research scientist from China. At the time of filing, he was conducting research in the United States focused on tissue engineering and bioadhesive materials. His work applies advanced mechanical engineering principles to develop hydrogels, scaffolds, and adhesive devices that address critical challenges in regenerative medicine, wound healing, and surgical care. By demonstrating both national importance and extraordinary ability, he was able to secure approvals in two distinct immigration categories.
Research with Substantial Merit and National Importance
The client’s research develops advanced biomaterials and bioadhesive medical devices that improve recovery from trauma, manage bleeding, and support regenerative therapies. This work holds clear national importance, as it strengthens healthcare innovation, reduces treatment costs, and supports U.S. priorities in biomedical technology and public health.
Scholarly Contributions and Recognition
The client has authored 18 peer-reviewed journal articles, 2 conference papers, and a book chapter, with studies published in leading journals such as Advanced Materials and Nature Communications. His work has been cited over 1,000 times, with multiple papers ranked among the top 1–10% most cited in materials science.
He has also completed at least 60 peer reviews for high-impact journals, underscoring his standing as a trusted authority in mechanical engineering and biomedical materials.
Expert Recognition
Independent recommenders provided strong endorsements, emphasizing the originality and utility of his research.
One expert remarked:
“In his research, [client] facilitates innovation in the field of mechanical engineering by providing new medical devices that are not limited by the challenges faced by traditional devices and technologies.”
This testimony reinforced the petition’s core argument: that his work is not only innovative in theory but also practical in application, making it highly valuable to healthcare providers and patients in the United States.
Dual Approvals and Outlook
The I-140 NIW petition was filed on October 23, 2023, and approved on November 3, 2023. His EB1B petition, filed on January 17, 2025, was approved on January 29, 2025. Both were filed with premium processing.
With NAILG’s guidance, the client secured approval under both NIW and EB1B. He is now well-positioned to continue advancing bioadhesive devices and tissue engineering research in the United States, supporting innovation in regenerative medicine and reinforcing U.S. leadership in healthcare technology.
