Success Story: NIW Approved Without Any RFE! An Visiting Assistant Professor Secure Success Smoothly
Client’s Testimonial:
“I am so glad I was able to file a successful I-140 petition (under EB2 NIW) with the NAmILG. My I-140 got approved in about 4 months with no RFE, which was really surprising given the current processing backlog.
I started the process with the NAmILG almost a year ago. Given my theoretical background (pure mathematics), I was not quite sure how to build a strong case. In particular, it was a challenging task for me to write a SOC in a way that is accessible to non-specialists. However, the lawyer assigned to my case was very helpful in navigating the entire process. She was available to answer many of my questions/concerns and was able to provide me with useful feedback. Overall, I am truly impressed with how smooth the entire process went with the NAmILG. It was a pleasure working with them, and I would highly recommend the Chen Immigration & Attorneys to anyone looking to begin their immigration journey.”
On January 23rd, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Visiting Assistant Professor in the Field of Mathematics (Approval Notice).
General Field: Mathematics
Position at the Time of Case Filing: Visiting Assistant Professor
Country of Origin: Sri Lanka
State of Residence at the Time of Filing: Texas
Approval Notice Date: January 23rd, 2025
Processing Time: 3 months, 29 days
Case Summary:
At North America Immigration Law Group (NAILG), we take great pride in supporting researchers whose work contributes to the advancement of U.S. scientific and technological frontiers. We are delighted to share the success story of an early career mathematician whose I-140 National Interest Waiver (NIW) petition was recently approved without RFE, recognizing his exceptional contributions to the field of pure mathematics.
Client Background and Field
The client holds a Ph.D. in mathematics and is an early-career scholar with growing expertise in the field of pure mathematics. His proposed endeavor focuses on developing and utilizing mathematical tools to investigate discrete structures such as random variables, random graphs, and cluster processes. This research not only advances theoretical mathematics but also supports emerging applications in information theory, combinatorics, and convex geometry – areas vital to improving data science, optimization, and computational modeling that underpin modern technologies and industries.
Petition Strategy and Highlights
When preparing this NIW petition, our legal team conducted a detailed evaluation of the client’s qualifications and contributions to the field.
To present a well-rounded profile, we emphasized key aspects of his academic record:
- 3 peer-reviewed journal articles (including 2 first-authored) and 4 research abstracts (3 first-authored), demonstrating his consistent scholarly productivity and leadership in his research area.
- 15 total citations to his published work, illustrating the growing impact and relevance of his research within the mathematical community.
- At least 2 peer review invitations for recognized international journals, confirming his role as a trusted expert capable of evaluating cutting-edge research.
Establishing National Importance
Our petition strategy focused on demonstrating how the client’s research in discrete mathematics is not merely theoretical but also foundational to several disciplines of national priority.
These arguments were strengthened by four expert recommendation letters that attested to the client’s influence, innovation, and continued potential to make meaningful contributions to the United States.
“Ensuring that [Client] work proceeds is thus not only important to the field, but to the United States as well.”
Case Outcome
The approval highlights both the client’s exceptional potential and the effectiveness of our evidence-driven approach in demonstrating national interest and professional merit.
We are honored to have assisted this talented mathematician in achieving this important milestone and look forward to seeing his continued impact on advancing mathematical science and its far-reaching applications across the United States.
