On July 11^th, 2024, and May 10^th, 2025, we received another EB-2 NIW (National Interest Waiver) and EB-1A (Alien of Extraordinary Ability) approvals for a PhD Candidate in the Field of Artificial Intelligence & Machine Learning (Approval Notice).

General Field: Artificial Intelligence & Machine Learning

Position at the Time of Case Filing: PhD Candidate

Country of Origin: China

State of Residence at the Time of Filing: Illinois

Approval Notice Date: July 11^th, 2024 (NIW) and May 10^th, 2025 (EB1A)

Processing Time: 9 months, 8 days (NIW), and 18 days (EB1A) (Premium Processing Requested)

Case Summary:

Following our client’s prior NIW approval, his petition for EB-1A classification was approved in just 18 days under Premium Processing with North America Immigration Law Group (NAILG). His work sits at the center of multiple high-impact areas: natural language processing, information retrieval, and recommender systems, with innovations that have significantly improved the usability and performance of language models in real-world contexts.

His contributions include:

● Efficient AI techniques for non-intrusive load monitoring (NILM)

● Robust defense models for securing recommender systems

● Novel methods to train NLP models under domain shift with limited data

● Enhancements to large language models for misinformation detection and faithful output generation

Our client’s published body of work includes 4 peer-reviewed journal articles, 39 conference papers, and 2 preprints. His research has been cited 713 times across at least 37 countries, and he has completed more than 50 peer reviews for major conferences and journals. His work has been supported by funding from the National Science Foundation (NSF).

One expert, in support of his EB-1A petition, summarized his impact as follows:

“[Client]’s artificial intelligence research is paving the way for better language processing capabilities. Language processing is a fundamental part of useful models that are able to detect patterns and misinformation hidden within large amounts of data. Detecting these patterns quickly, accurately, and with limited resources offers a host of benefits in vital fields. In public health, for example, these sorts of models are integral to mapping out different misinformation trends in fast-moving pandemics. [Client] has shown how to reduce the computational resources needed to complete these sorts of broad analyses. Moreover, his work has made natural language processing more usable across different fields. [Client]’s work has clearly improved artificial intelligence capabilities, and I encourage you to view his work favorably.”

The preparation of his petition involved a focused collaboration with the legal team at North America Immigration Law Group, who worked to frame his work in terms of its national relevance and technical significance. By anchoring the petition in both the originality of his research and its wide-ranging applications, from public health to digital infrastructure, the case presented a compelling argument that led to his EB-1A approval in just 18 days.
