General Field: Cardiology

Position at the Time of Case Filing: General Medical Practitioner

Country of Origin: Nigeria

Country of Residence at the Time of Filing: United Kingdom

Approval Notice Date: October 3rd, 2023

Processing Time: 6 days (Premium Processing Requested)

Case Summary:

Furnished with an MBBS degree, our client, a general medical practitioner, is highly qualified with comprehensive experience in the field of cardiology. He possessed all the skills, including 12 peer-reviewed journal articles, 3 peer-reviewed conference abstracts, and 1 book he published, accumulating 45 citations. To further substantiate the fact that his work has received numerous citations, and to demonstrate the utility of his work, we concluded that his extensive body of work has been published in highly respected journals within the field. This highlights the significance and undeniable necessity of his work on a global scale.

In order to convey the aforementioned accomplishments in an effective and persuasive EB-2 NIW (National Interest Waiver) petition, our client hired the North America Immigration Law Group. When we evaluated his credentials, we reviewed his proposed research focusing on performing cardiovascular disease research by leveraging AI machine learning models, data analysis, bioinformatics, and epidemiology to reduce patient mortality and healthcare spending. We gathered that his research is crucial because it significantly benefits global health here in the United States.

In light of this, we prepared a petition packet specifically for him, incorporating all of the above-mentioned information as well as the fact that he had already completed 9 peer reviews for prestigious journals. This attests to his active involvement in evaluating peers’ work, claiming his foundational role and extraordinary ability in the field.

Considering his record of successful research in an area that significantly furthers U.S. interests, he offers contributions of such value that, even under the assumption that other competent U.S. workers are available, he would benefit the U.S. overall. His research addresses critical issues related to improving cardiovascular disease treatment efficacy, enhancing the accuracy of predicting cardiovascular disease occurrences, and alleviating the financial burden of healthcare. His successful research into global health emergencies serves as evidence of this. He is also uniquely well-positioned to pursue this work, considering his experience, leadership, and expertise in the field.

Given the above aspects and the evidence presented therein, he satisfies the criteria for securing an NIW visa. Thus, this case was handled with the same diligence as we handled more than 32,000 other I-140 approved cases. We are happy that USCIS approved our client’s EB-2 NIW petition without any further request for evidence, indicating that our team did a good job of preparing his case. We would like to thank and applaud our client for entrusting our law firm with his NIW application and allowing us to be a part of this wonderful story.
