Case Summary:

The EB1-A or Alien of Extraordinary Ability is a kind of visa issued to foreign nationals who possess extraordinary expertise in a chosen field of study. Such a client came to us from China. He was one of the few leading machine learning, cloud computing, spatiotemporal data mining, and big data experts in data science. And he had achieved a consistent and notable record of success and influence in these areas of study. So his case needed fine-tuning once we had all the information from his academic and professional background. This our team did with remarkable expertise. We made sure that he got the best and fastest service possible. So, thanks to the premium processing upgrade, his case was approved only 20 days from filing.

Below are some of the factors which played in his favor during the adjudication:

  • His work has been supported by notable funding from such renowned sources as the National Science Foundation and NASA, indicating the value of his work to U.S. interests.
  • His authority in the field has been recognized by invites to review and evaluate the work of his peers no fewer than 48 times.
    In addition to directly advancing machine learning, cloud computing, spatiotemporal data mining, and big data through his original research and peer review service, he has actively engaged his peers in the field of data science by authoring and co-authoring 23 peer-reviewed articles and 1 book that have been published in international journals and conferences.
  • Additionally, his overall work related to the improvement of machine learning, cloud computing, spatiotemporal data mining, and big data technology and approaches has been cited 1,231 times in at least 53 countries. Considering this widespread use of his work, it is clear that he is a keystone researcher in the field of data science.
  • Furthermore, his study has received funding from the National Aeronautics and Space Administration and the National Science Foundation.
  • He has also received letters of recognition from 4 experts in his field. Two of these said the following about his work:

“[The client] is an exceptional researcher in the discipline of data science research. He has made important contributions to data management, machine learning infrastructure, and artificial intelligence algorithm development. Based on his history of success to date, [the client] is certain to have a positive impact on data science through his future endeavors for many years to come.”

“[Client’s] research into tourism patterns is of great value to the advancement of the tourist industry of the United States by identifying what attractions see the most traffic and what areas require improvement to increase tourism. With an expected increase in tourists in the coming years, his work is directly supportive of the travel and tourism industry in the United States.”

Hence, his case approval was no surprise to us. We are happy to have been of aid to him and we look forward to further collaboration with him in the future.
