General Field: Biochemistry

Position at the Time of Case Filing: Postdoctoral Research Associate

Country of Origin: Sri Lanka

State of Residence at the Time of Filing: Washington

Approval Notice Date: February 25^th, 2023

Processing Time: 16 days (Premium Processing Requested)

Case Summary:

Based on the huge number of successful cases, North America Immigration Law Group has developed the most up-to-date winning strategies for the NIW category, which enable us to offer our “Approval or Refund” services to many of the NIW cases we take. However, there are certain prerequisites to be fulfilled by an individual including:

The foreign national must be in a position to advance the proposed endeavor.
The applicant must present evidence that the U.S. would benefit on balance to waive the job offer criteria for an EB-2.
A proposed endeavor, holding substantial merit and national importance.

Our client, a Postdoctoral Research Associate from Sri Lanka, approached us to file an NIW (National Interest Waiver Petition) on her behalf.

She has completed her Ph.D. in chemistry and as an expert in the field of biochemistry, her proposed endeavor is to distinguish the redox properties of flavins and iron-sulfur clusters in multi-subunit protein complexes and single subunit proteins related to electron transfer pathways to apply these mechanisms in sustainable energy technologies. Therefore, to make a persuasive case in her favor, we included the following details in her petition packet:

Her work has resulted in 7 peer-reviewed journal articles (3 of them first-authored).
Her publications have been cited a total of 61 times according to Google Scholar.
Her study has received funding from the National Science Foundation and an Energy Frontier Research Center funded by the United States Department of Energy. This funding supports projects that advance national health, welfare, and prosperity and projects that address the nation’s energy, environmental, and nuclear challenges through science and technology solutions.
She has even received 4 recommendation letters from her fellow experts in the field. Out of those one of the excerpts is mentioned below:

“...Considering global goals to reduce the amount of carbon in the atmosphere and to develop energy sources without carbon emissions, as outlined in the Paris Agreement, electron bifurcation implementation for energy applications is of international concern. It is without a doubt that the continued research of [client], as a leader in electron bifurcation studies, is essential to the advancement of the field and global climate change mitigation initiatives.”

Furthermore, her research advancing her proposed endeavor is of great importance because it has substantially advanced scientists’ understanding of electron bifurcation mechanisms in electron transfer flavoproteins and spectro-electrochemistry of electron bifurcating flavin cofactors.

In several of her cutting-edge research projects, our client has made novel insights about the mechanisms and implications of the electron bifurcation process. This new information is essential for scientists to characterize electron bifurcation and its uses for a wide range of technologies, especially in the renewable energy sector.

On that account, she received her NIW approval in 16 days only with our team’s efforts and the Premium Processing Service. We are pleased to have been a part of her success story and would like to wish her good luck in her upcoming endeavors.
