Success Stories: Vietnamese Postdoctoral Researcher Earns EB1A Approval for Pioneering Biocatalysis and Sustainable Polymer Research
Client’s Testimonial:
“It is unbelievable. My case was not strong at the beginning, but with the strong support from Chen Immigration Law Firm, I got approval! Their expertise and guidance made all the difference in my EB1A application process. I’m thrilled and grateful for their assistance!”
On September 18th, 2025, we received another EB1A (Alien of Extraordinary Ability) approval for a Postdoctoral Researcher in the field of Chemical Engineering (Approval Notice).
General Field: Chemical Engineering
Position at the Time of Case Filing: Postdoctoral Researcher
Country of Origin: Vietnam
State of Residence at the Time of Filing: Illinois
Approval Notice Date: September 18th, 2025
Processing Time: 1 year, 3 months, 21 days
Case Summary:
We are pleased to share the EB1A (Alien of Extraordinary Ability) approval of a postdoctoral researcher from Vietnam. At the time of filing, she was conducting research in the United States on sustainable chemical and biochemical processes. Her work focuses on one-carbon (C1) bioconversion, nanobiocatalysis, and biodegradable polymers, offering innovative solutions to reduce emissions and replace environmentally harmful materials. Backed by a strong record of publications, citations, and peer review service, she established herself as a persuasive candidate for EB1A approval.
Extraordinary Research Contributions
The client has advanced methods for C1 bioconversion, turning a potent greenhouse gas into valuable products with reduced environmental impact. Her nanobiocatalysis research has improved reaction efficiency and stability, enabling greater industrial application of lab-based discoveries. In addition, her work on biodegradable polymers has provided sustainable alternatives to conventional plastics, directly supporting environmental and public health goals. Together, these contributions underscore both the originality and enduring value of her research.
Academic Record and Recognition
The client holds a Ph.D. in chemical engineering and has authored 5 peer-reviewed journal articles and 2 book chapters. Her studies have been cited 237 times by independent researchers, with several ranking among the top 10 percent of most cited in chemical engineering for their years of publication. She has also completed at least 14 peer reviews for respected journals, reflecting her recognition as a trusted authority in her discipline.
Expert Endorsements
Independent experts highlighted the novelty and national relevance of her work.
One recommender explained:
“[Client]’s work will continue to stimulate novel approaches for biomanufacturing to advance the US bioeconomy and community wellbeing.”
This testimony reinforced the broad scientific and practical importance of her contributions.EB1A Approval and Outlook
The I-140 EB1A petition was filed on May 28, 2024. USCIS issued a Request for Evidence (RFE) on June 20, 2025, which was overcome with further evidence of her publication record, citation impact, and peer review activity. The petition was approved on September 18, 2025.
With NAILG’s support, the client secured EB1A approval despite the RFE challenge. She is now poised to continue advancing sustainable chemical and biotechnological innovations in the United States, contributing to clean energy development, environmental protection, and U.S. leadership in chemical engineering.
