“Having professional support during this process was essential for the success of my case. I highly recommend this firm.

A series of revisions from my side and their side leveraged the quality of the materials. Finally, having professionals reviewing and organizing the paperwork alleviated the stress and provided a framework that, in my case, helped me balance my daily professional and personal endeavors. Thank you for your hard work and professionalism.”

On March 15th, 2022, we received another EB-2 NIW (National Interest Waiver) approval for a Research Associate in the Field of Epidemiology (Approval Notice).

General Field: Epidemiology

Position at the Time of Case Filing: Research Associate

Country of Origin: Mexico

State of Residence at the Time of Filing: Kansas

Approval Notice Date: March 15th, 2022

Processing Time: 12 months, 20 days

Case Summary:

An expert in the field of epidemiology, came to NAILG seeking help with her NIW (National Interest Waiver) petition. Her proposed endeavor was to continue her research on modeling infectious diseases in order to identify the infection dynamics of pathogens in human and animal populations to promote overall animal and public health and emergency preparedness. It was thus clear that her research is of great importance because it addresses the spread of disease within livestock and wildlife populations. This is crucial to preventing such diseases from being transmitted to humans or causing massive economic loss to farmers and other livestock owners.

It was due to this reason that her work has been supported with funding from 5 leading institutions within the U.S. itself. These institutions are the Columbus Zoo and Aquarium, the National Science Foundation (NSF), the National Institutes of Health (NIH), the U.S. Department of Homeland Security (DHS), and the Oak Ridge Institute for Science and Education (ORISE) in collaboration with the U.S. Department of Energy. This indicated the innate value of her research for the United States of America.

On the other hand, it is because of the significant value of this work that she could get 4 impressive letters recommending her work in the area. One of them had the following to say:

“This work is crucial to the U.S., in particular, because Mexico (which is where [the client] conducted her study) has a similar ecosystem to many regions of the U.S., including common environments and species. Understanding the factors that drive infectious diseases in Mexico is thus highly applicable to improving U.S. interaction with the natural environment. Research like [the client] produces is vital to improving understanding of such diseases and preventing humans from coming into contact with them. These findings are essential to controlling the spread of infectious diseases and ensuring that the U.S. is better prepared in the event that this occurs again.”

Similarly, our team could find various supporting documents to aid her petition letters. Some of the facts found in them were as follows:

  • She has been invited to conduct peer reviews for at least 5 authoritative journals in the field, including international scientific journals of repute.
  • Her research has resulted in 13 peer-reviewed journal articles (5 of them first-authored) and 1 informational piece for the United States Department of Agriculture (USDA).
  • These publications have also been cited a total of 100 times according to Google Scholar.
  • Our client has pursued research directly related to her proposed endeavor of modeling infectious diseases in order to understand and control pathogens in human and animal populations for 13 years.

Thus, her education, experience, expertise, record of publication and citation, and history of successful research in the field all indicate that she is well positioned to advance the proposed endeavor. These facts hence establish that it is beneficial to the United States to waive the requirements of a job offer and labor certification for her. So, she received her NIW approval without an RFE and decided to retain our services for her I-485 filing. We are grateful for her trust in us and we wish her the very best in life.
