Case Summary:

We’re excited to share the I-140 National Interest Waiver (NIW) approval for a talented Ph.D. holder, whose work in statistical data privacy is paving the way for safer digital environments and more accurate, privacy-aware data applications.

Currently working as a quantitative analytics specialist in the financial sector, the client focuses on developing and analyzing statistical and machine learning models that enhance both privacy and accuracy in data-driven decision-making. Their research centers on exploring theoretical properties of widely used data mining techniques and statistical methodologies, with the goal of optimizing their performance in contexts such as fraud detection, fair lending, and electronic health record privacy.

To support their NIW petition, we presented:

● A research record that includes 2 peer-reviewed journal articles, 2 first-authored conference papers, and 1 preprint;

● A citation count of 20, including a top 10% most-cited article in the field of Mathematics;

● 2 confirmed scholarly peer reviews for leading journals.

We emphasized the national importance of the client’s work, particularly given growing concerns over digital privacy in the U.S., where data tracking by tech companies is widespread. Their innovations contribute directly to enhancing cybersecurity, data privacy, and differential privacy – areas identified by the U.S. National Science and Technology Council as critical and emerging technologies vital to national interest.

Despite receiving a Request for Evidence (RFE), the petition was successfully approved after 7 months following an upgrade to premium processing. We demonstrated that the client’s education, specialized training, impactful publications, and current employment all underscore their exceptional ability to advance their proposed endeavor.

We congratulate our client on their success and look forward to seeing continued advancements that promote both the privacy and utility of data in today’s increasingly interconnected world.
