Case Summary:

A machine vision and learning expert from South Korea hired North America Immigration Law Group ( to help him obtain EB-1A (Alien of Extraordinary Ability) petition approval. We made sure to ask him questions about his research and review his credentials before taking on his case. Once we confirmed that we could help him secure EB1A petition approval, we started gathering a wealth of information pertaining to his work. These are some of the main points we focused on:

  • Thanks to Google Scholar, we confirmed that our client’s work had collected 498 citations by the time we filed his case. We demonstrated that these citations came from independent and leading researchers around the world, indicating the major significance of his work.
  • We also listed our client’s productive and exemplary publication record: 7 peer-reviewed conference and journal articles, 1 online article, 2 patents, and 21 computer programs.
  • To demonstrate our client’s respected status in the field of machine vision and learning, we listed the 6 times he had assessed the work of his peers for a handful of prominent scientific periodicals.

We made sure to establish our client’s extraordinary ability in the field, and that he is one of only a handful of researchers whose work on deep machine learning benefits the United States to a great extent. These are some other elements of his EB1A petition packet that paved the way for case approval:

  • We noted our client’s Ph.D. in Medical Engineering and Medical Physics and convinced the USCIS that he possesses the practical and theoretical skills needed to continue conducting impactful research.
  • Based on the data we gathered, we established that the application of our client’s research on precision medicine enables more effective diagnosis and treatment of severe conditions such as cancer and heart disease.
  • We incorporated four recommendation letters into his petition packet, one of which contained this statement: “It is therefore in the best interests of the United States to continue to support [Client’s] work, which holds wide-ranging benefits for public health, public safety, and the economy.”

As our client filed his petition with Premium Processing, he only waited 5 days for the USCIS to take action on his case. We congratulate him for obtaining petition approval, and we wish him the best as he takes on the final step of the green card process: filing an I-485 application.
