Case Summary:

“[Client’s] skillset is irreplaceable, given its immense benefits to the improvement of machine learning and artificial intelligence technologies. It is imperative that he be allowed to carry out his research uninterrupted so that the United States is able to benefit fully from its value.”

The excerpt above is taken from one of two recommendation letters written by experts in the field, highlighting the significant merits of our client’s research and its alignment with national interests.

A Chinese Ph.D. student approached us for assistance in filing his I-140 NIW application. We were supposed to demonstrate that his research is of national importance and holds substantial merit. After an initial review of his background, we determined that he was a strong candidate for this visa category, as his credentials closely aligned with USCIS requirements.

With an M.S. in computer science and technology, our client focuses on developing artificial intelligence (AI) models designed to create safe and effective computer-aided systems. His work advances AI applications in healthcare, virtual assistants, and automated decision-making.

After carefully evaluating his qualifications, we began drafting his case and built a strong argument to support his NIW petition. Using our proven legal strategies, we structured his case to highlight the following:

  • Summary of His Research
  • Our client’s work is highly significant as it has broad implications for the United States. A 2023 study found that 1 in 4 patients admitted to U.S. hospitals experience harm, with nearly a quarter of adverse events considered preventable. This underscores the urgent need for improved patient safety measures. One way to enhance healthcare outcomes is by implementing advanced technologies. In this context, our client’s AI research is crucial in improving efficiency, diagnostic accuracy, and personalized patient care.

    The widespread adoption of AI in the medical field is expected to generate up to $360 billion in savings in the U.S. alone. Additionally, AI-driven improvements in patient care could reduce hospital stay durations by 25%, leading to better resource management. Our client’s work ensures that AI-driven healthcare remains fair and reliable, reinforcing the United States’ position as a leader in AI-powered medical advancements. His contributions not only build trust in AI-based healthcare solutions but also enhance patient care and overall public health.

  • Citations and Publications
  • At the time of filing, our client had accumulated 108 citations from 3 peer-reviewed journal articles, 3 peer-reviewed conference papers (including 1 as the first author), one preprint, and 2 granted patents. His academic background, extensive publications, and the recognized impact of his research in AI further strengthened his case.

  • Recommendation Letters
  • To support his petition, we included two recommendation letters from experts in his field. These letters confirmed that his contributions align with U.S. national interests and emphasized the importance of his continued research.

    Our dedicated efforts in preparing a strong case demonstrated our client’s significant role in advancing AI for healthcare applications. As a result, he received I-140 NIW approval in just two months and six days, without the need for additional evidence requests (RFE). We appreciate his trust in our law firm and are honored to have been part of his successful immigration journey. We wish him continued success in his future endeavors.
