Client’s Testimonial:

“This is really good news and a great way to start the new year. The attorney performed a great job during the preparation and finalization of my documents. I appreciate the hard work put into it. Thank you!”

On January 11^th, 2022, we received another EB-2 NIW (National Interest Waiver) approval for a Ph.D. Student in the Field of Cardiology (Approval Notice).

General Field: Cardiology

Position at the Time of Case Filing: Ph.D. Student

Country of Origin: Nigeria

State of Residence at the Time of Filing: South Carolina

Approval Notice Date: January 11^th, 2022

Processing Time: 7 months, 10 days

Case Summary:

As a proficient in the field of cardiology, our client from Nigeria proposed to continue his investigation here in the United States into the impact of microRNA 33a, COVID-19, and ABCA1 and ABCG1 transporter genes on vascular smooth muscle cell activity in order to facilitate the development of novel treatments for atherosclerosis.

When he approached us by submitting his merits and achievements in the field for our review, impressed with his academics, we chose to help him in preparing a strong NIW (National Interest Waiver) petition on his behalf. According to the standard of proof for petitions filed for National Interest Waiver cases as per the Matter of Dhanasar, we extracted all the important details and included them in the NIW petition packet in the best interest of our client.

We started off by specifying his M.Sc. degree in human sciences and his years of expertise in his field, which is relevant to the mitigation of the impact of cardiovascular diseases on public health and the economy. His research seems to be of great importance as it addresses some of the greatest public health burdens facing the world today. Even four of his fellow experts in the field provided additional insight into the merit of this endeavor, and one of them stated the below-mentioned in his recommendation letter:

“One of [client's] most significant achievements for the field are his investigation on how the COVID-19 pandemic has broadly affected eating habits. Subsequently, he narrowed his focus to populations reliant on food stamps and public assistance. In a case study, his results provided two key findings, the first indicating the high correlation between the number of COVID-19 cases and food insecurity, meanwhile, the second finding pointed to old age and poverty as significant predictors of COVID-19 vulnerability and as factors underlying food insecurity and reliance on public assistance. All in all, [client’s] research serves to raise awareness about the impact of COVID-19 on public health nutrition in the United States.”

Our team utilized all 4 letters of support along with the following record of his publication and citation, and history of all his successful positions in the field, indicating that he is well-placed to grow in his chosen field:

His research has resulted in 7 peer-reviewed journal articles (4 of them first-authored).
His work has gathered a total of 47 citations by other experts in the fields of his study.
He has also been invited as a judge to conduct peer reviews 4 times already.
Besides, his work received financial aid from the American Heart Association. It is further evidence of the national importance of our client’s research in advancing his proposed endeavor.

These attributes demonstrate that our client’s work is beneficial to the United States since he has established eligibility for a national interest waiver, and thus, his petition successfully achieved approval from USCIS. Our team at the North America Immigration Law Group wishes him all the best as he moves forward in the field of cardiology and improves the overall public health of the United States.
