Success Stories: In Only A Week, Mexican Postdoctoral Research Associate in the Field of Toxicology Secures NIW Approval
On September 20th, 2023, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Research Associate in the Field of Toxicology (Approval Notice).
General Field: Toxicology
Position at the Time of Case Filing: Postdoctoral Research Associate
Country of Origin: Mexico
State of Residence at the Time of Filing: Illinois
Approval Notice Date: September 20th, 2023
Processing Time: 7 days (Premium Processing Requested)
Case Summary:
Our firm was hired by a Mexican postdoctoral research associate with a Ph.D. in toxicology to assist him in filing a National Interest Waiver (NIW) petition. We found that he was working to continue his research on characterizing the toxicity of widely used chemicals and pollutants to understand their effects on reproductive health and to develop methods for regulation and damage mitigation. Our team determined that he had a good chance to acquire approval for his NIW petition, and agreed to take him on as a client. His petition contained the following details:
- He has an extensive record of publications, with 10 peer-reviewed journal articles (4 of them first-authored, 1 accepted). His work has been published in no less than 2 highly-ranked journals, indicating the quality of his research is top-notch.
- The influence of his work is significant, having been cited 121 times at the time of the petition, with at least 4 of his papers being among the most highly cited in their field and year of publication.
- Our client’s proposed endeavor also has broad implications for the United States, as his findings provide novel insights that are necessary to address declining birth rates in the U.S. and improve reproductive health. Around 19% of women aged 15 to 49 years old suffer from infertility in the U.S., and around 26% experience impaired fecundity. In addition, 1 out of 33 children born in the U.S. suffer from birth defects, making it an important national issue. His research provides essential insights into the toxic effects of everyday compound exposure on reproductive health. Thus, his findings are necessary to improve fertility and support healthy American births.
- Lastly, our client has also received letters of recommendation from 2 experts, one of whom said:
“[Client] is a highly skilled and thorough expert making important contributions to toxicology. His work is novel and makes great strides in explaining the mechanisms of toxicants on the female reproductive system. Clearly, [Client]’s work meets a fundamental need and supports continued reproductive health in the U.S. He must be encouraged to continue his work in the country.”
To conclude, after the work done by our committed team, alongside the USCIS’s premium processing service, we managed to get approval in just a week. We thank our client for having faith in our team and wish him the best.
