Case Summary:

At North America Immigration Law Group – WeGreened.com, we recently received an EB1B approval for an Assistant Professor in the field of environmental hydrogeology. The beneficiary’s outstanding ability, highly skilled background, and impressive record of achievement provided a strong case for his EB1B petition. His specialized research had focused on the development of analytical models that can simulate the flow of fluids through porous media. His research work had resulted in at least 6 peer-reviewed scholarly articles in leading journals and conference proceedings. Furthermore, the beneficiary had a total of 33 citations by researchers around the world for his publications before filing the petition. In addition, he had been invited to review 8 articles submitted to prestigious journals. The petitioner in this case was a top US technological research university. The beneficiary’s outstanding expertise is summarized in a quote by an independent recommender, “The remarkable outcomes of [the beneficiary’s] research are beyond noteworthy. Indeed, his computer model and simulations are much needed for environmental engineers because more than a third of the world’s groundwater supply is located in karst aquifers. This groundwater can easily become polluted because karst aquifers are constantly changing in location and the flow of groundwater through the pores it creates allow contaminants to remain in the water indefinitely. When this is taken into account with the importance of [the beneficiary’s] carbon sequestration project for the atmosphere, it becomes clear that he is one of the most critical researchers in the field of hydrogeology.” It was our goal to prove that this beneficiary qualifies for classification as an outstanding professor or researcher given the international recognition for his outstanding achievements. His petition was approved in 3 ½ months.
