Success Story: EB-1A Approval after RFE for a Condensed Matter Physics Expert under Direct Premium Processing
On May 28th, 2026, we received another EB-1A (Alien of Extraordinary Ability) approval for a Postdoctoral Researcher in the Field of Condensed Matter Physics (Approval Notice).
General Field: Condensed Matter Physics
Position at the Time of Case Filing: Postdoctoral Researcher
Country of Origin: China
State of Residence at the Time of Filing: Tennessee
Approval Notice Date: May 28th, 2026
Processing Time: 1 month, 20 days (Premium Processing Requested)
Case Summary:
A strong EB-1A petition must do more than list accomplishments. It must show how the record, viewed as a whole, places the petitioner among the small percentage who have risen to the top of the field. For this client, a condensed matter physics expert specializing in crystal growth and material characterization, that meant presenting a record of sustained influence, independent reliance, peer recognition, and major scientific contribution.
The client’s work focuses on crystal growth and the characterization of quantum and topological materials. Within condensed matter physics, he is especially recognized for research involving the growth and tuning of the magnetic topological insulator MnBi₂Te₄, along with related work on strain-driven topological phase transitions and competing electronic states in advanced materials. He is currently conducting research in the United States, where his work involves designing experiments, growing crystals, building apparatuses, conducting measurements, analyzing data, and developing theoretical models.
The petition was filed under the I-140 EB-1A category with direct premium processing and later received a Request for Evidence. In responding to the RFE, we focused on clarifying the overall significance of the client’s record rather than relying on isolated metrics. The response connected his publication history, citation impact, peer-review service, funded research, and expert testimonials to show that his contributions had influenced the direction of condensed matter physics and had been relied upon by researchers working on next-generation quantum, electronic, and energy-related materials.
The client’s credentials included:
- 12 peer-reviewed journal articles, including 5 first-authored articles
- 16 conference abstracts, including 4 first-authored abstracts
- 853 citations to his published work
- At least 12 completed peer reviews
- Research support from multiple major funding organizations
The case was further strengthened by 8 recommendation letters from experts in the field, including independent experts who were familiar with the client’s work through its influence on their own research. These letters helped corroborate the objective evidence and explain the practical and scientific significance of his contributions. One expert stated that:
“As such, [Client’s] approach establishes a foundation for more efficient electronic devices, more robust quantum systems, and improved energy storage solutions, directly supporting technological leadership, national security, and sustainable energy initiatives in the United States.”
By organizing the evidence around peer trust, independent reliance, high-impact publication, funded research, and continued work in the area of extraordinary ability, we demonstrated that the client satisfied the EB-1A standard and that his continued work would prospectively benefit the United States.
After the RFE response, USCIS approved the I-140 EB-1A petition. We congratulate the client on this important approval and wish him continued success in advancing condensed matter physics, crystal growth, and material characterization research.
