Success Stories: A Vietnamese Postdoctoral Researcher Working in Mathematics Obtains NIW Approval with Help from North America Immigration


Client’s Testimonial:

“Thank you for your tremendous help!”

On October 6th, 2022, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Researcher in the Field of Mathematics (Approval Notice).

General Field: Mathematics

Position at the Time of Case Filing: Postdoctoral Researcher

Country of Origin: Vietnam

State of Residence at the Time of Filing: Ohio

Approval Notice Date: October 6th, 2022

Processing Time: 6 months, 23 days

Case Summary:

“[The client’s] work has important applications from which the United States profits. For example, having a deeper understanding of these dynamical systems is critical to assisting banking interests. The United States is home to some of the leading banks in the world, while U.S. financial markets are among the largest and most liquid worldwide. In 2018, finance and insurance accounted for almost 8 percent of the country’s gross domestic product. [The client’s] research provided a crucial theoretical background to improve this market in the United States, which proves that the country has ample reason to promote his ongoing studies.”

The above statement is a testimony of our National Interest Waiver client’s nationally important work in the field of mathematics. Written by one of the 4 recommending experts, such statements went a long way in proving his value for the country. Our team made sure that his petition packet contained everything that would positively win him the approval without an RFE. Some of them are listed below:

  • Details of his proposed endeavor: His proposed endeavor was to continue his research on developing general techniques to utilize the strengths of dynamical systems, combinatorics, and number theory to merge disconnected theories into a unifying tool that addresses difficult mathematical problems applicable to a wide range of applications.
  • Importance of his work: His research advancing his proposed endeavor is of great importance because it is providing novel insights into the structures of dynamical systems and uncovering hidden patterns in seemingly disordered mathematical objects. He has also made key advances in the understanding of two important objects in dynamical systems, correlation sequences, and nilsequences, discovering that their differences are negligible along integers and prime numbers.
  • Importance for the U.S.: His proposed endeavor also has broad implications for the United States as his research on the discovery of novel patterns in prime numbers is instrumental to the development of next-generation cryptological techniques.
  • Funding Information: Due to its clear national importance, his research has in fact been supported with funding from the National Science Foundation.
  • Publication, Citation, and Review Experience: His research has resulted in 8 peer-reviewed journal articles (5 of them first- or sole-authored) which have been cited a total of 29 times according to Google Scholar. He has also completed 5 reviews to date.
  • Testimony of Experience: He has pursued research directly related to his proposed endeavor of developing general techniques to utilize the strengths of dynamical systems, combinatorics, and number theory for approximately 7 years.
  • Letters of Recommendation: He had obtained 4 letters of recommendation, 1 from a dependent expert who knew him personally and the rest from independent researchers.

All of these factors contributed to building a solid foundation for his petition, ultimately winning the approval from USCIS. We are glad to have been a part of this process.
