On December 5th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Research Assistant in the Field of Environmental Engineering (Approval Notice).
General Field: Environmental Engineering
Position at the Time of Case Filing: Research Assistant
Country of Origin: China
State of Residence at the Time of Filing: Texas
Approval Notice Date: December 5th, 2025
Processing Time: 1 year, 20 days (Premium Processing Upgrade Requested)
Case Summary:
An environmental engineering researcher recently obtained NIW approval on the strength of work focused on understanding how human activities interact with natural systems under a changing climate. With an M.S. in Environmental and Water Resources Engineering, this researcher has been developing advanced Earth system model modules that combine sophisticated modeling techniques with observational data. The goal is to improve how we characterize coupled human-nature systems so that decision-makers can better respond to climate-related risks.
A key element in the petition was the researcher’s publication record. At the time of filing, the work has resulted in three peer-reviewed journal articles (including one first-authored), one first-authored preprint, and three conference abstracts (two first-authored). These outputs have collectively received 129 citations, indicating that other scientists are drawing on these methods and findings in their own studies of hydrology, climate processes, and environmental modeling.
In addition to publishing, the researcher has completed at least 12 peer reviews for scholarly journals. This type of service is typically reserved for individuals whose expertise is trusted by editors to assess the quality and relevance of submitted manuscripts. It provided further evidence that the researcher is an active participant in the scientific community and is relied upon to help maintain standards in the field.
By organizing this evidence into a clear NIW framework, NAILG demonstrated that the case met the required criteria, and the approval reflects recognition that these efforts support improved understanding of climate–human interactions and help inform more effective, evidence-based decision-making in the United States.
