Case Summary:

A postdoctoral research fellow hired North America Immigration Law Group ( to file an EB-2 NIW (National Interest Waiver) petition on her behalf. Our client with a Ph.D. in environmental and occupational health and incredible knowledge in the field of health risk assessment hired us as she knew that our law firm would walk miles for her case to be triumphant. We started preparing her case after thoroughly evaluating her credentials, and we asserted that we could help her accomplish this goal of getting the national interest waiver visa. We implemented our unprecedented legal strategies to compose her NIW case and demonstrated the following in our petition packet:

Summarized her Research Work:

We noted her research using physiologically-based pharmacokinetic models, in vitro-to-in vivo extrapolation, and other computational and statistical modeling-based analyses to evaluate human health risks in order to improve health policy and decision-making, and we deduced how our client’s work is relevant to health risk management, food security, public health protection, and pharmaceutical development here in the United States.

Stated Citation Count, Publication, and Peer-Review Experience:

At the time of filing, our client had gathered 91 citations from the 13 peer-reviewed journal articles (4 of them first-authored or co-first-authored) she published. Thus, her education and training, her documented record of scholarly publication, and the recognized influence of her research in the field highlight that she is well-equipped to advance work on the improvement of health policy and decision-making through human health risk assessment. Her 5 key projects have also been included as evidence of her contributions and expertise in the field of health risk assessment. Her expertise and experience have also been recognized through her appointment to leadership positions within the field of health risk assessment, including her position as head of the Department of Environmental and Occupational Health and as a peer reviewer, whereas she has evaluated several articles of her peers at least 2 times.

Integrated Recommendation Letters:

To fortify our client’s EB-2 petition, we added four letters of recommendation, which she acquired from fellow researchers in the field, corroborating that she has conducted ground-breaking research regarding the state of food security in Mongolia, and her findings and methodologies have inspired related studies around the world. One of the recommenders contributed the below-stated words:

“The U.S. Environmental Protection Agency is responsible for setting exposure guidelines for thousands of naturally occurring and manufactured chemicals, as stated under the Toxic Substances Control Act. By facilitating the setting of exposure limits with increased consistency and accuracy, [client’s] research is enhancing the environmental health of the United States and bettering conservation efforts. Her findings are therefore highly significant for the United States.”

Our constant assistance to our client in her case proved that she has provided critical information to international organizations that aid in efforts to reduce and eliminate global hunger. Therefore, she secured the I-140 NIW approval without any further request of evidence. We truly thank her for choosing our law firm and allowing us to be a part of her successful journey.
