“Thank you very much for helping with the O1 application.”

On January 27th, 2020, we received another O1-A (Individual with extraordinary ability or achievement) approval for a Senior Research Scientist in the Field of Medical Computer Vision (Approval Notice).

General Field: Medical Computer Vision

Position at the Time of Case Filing: Senior Research Scientist

Country of Origin: China

Country of Residence at the Time of Filing: United Kingdom

Approval Notice Date: January 27th, 2020

Processing Time: 12 days (Premium Processing Requested)

Case Summary:

A senior research scientist from China hired North America Immigration Law Group (NAILG) to help her file an O-1A (Individuals with Extraordinary Ability or Achievement) petition. In order to receive notification of case approval, she needed to show that she was an individual with extraordinary ability who was temporarily entering the United States to continue work in her area of specialization. With our help, our client accomplished this goal and received petition approval in just 12 days (with Premium Processing).

Before we started to work on the case, we conducted a thorough evaluation of our client’s credentials to verify her chances of O1-A approval. We confirmed that she held a master of research with a focus on medical image segmentation, intra-operative 3D navigation, and surgical robotic path planning. We successfully determined that our client was an expert in understanding deep learning, machine learning, and computer vision. Our goal was to prove to the USCIS that our client’s findings are of great importance due to their enormous impact in the field of medical computer vision. Her winning O-1A petition packet also included:

  • Original contributions: At the time of filing, our client had already been cited 81 times. This proved the value of her work not just to other researchers but to the field of medical computer vision as a whole.
  • Authorship: The many years that our client has dedicated to the field have resulted in 11 peer-reviewed scientific articles, all of which were published in well-known scientific journals.
  • Judge of others’ work: To highlight the fact that our client’s ideas and opinions are respected by other researchers in the field, we presented her peer review record- 11 reviews conducted by the time we filed her case.

To validate the extent of international influence her work had garnered, our client procured five written advisory opinions signed by top-level experts. One of the recommenders stated: “Given her substantial contributions to the medical computer vision field, I can confidently state that [client] will continue to provide her valuable contributions to our community, and she will most certainly be a major asset to the United States.”

After two months of diligent work, we successfully demonstrated that our client had satisfied the O1A criteria. We congratulate her for securing O1-A petition approval and we thank her for trusting our law firm.
