Case Summary:

When an expert in advanced engineering materials from Pakistan approached our firm for his National Interest Waiver approval, we made sure to first familiarize him with the details of the EB2-NIW criteria and then once the retainer had been signed we started working on his case. Our team gathered evidence to prove his worth to the nation and found the following information:

We found that with a Ph.D. in environmental science, his proposed endeavor was to work on utilizing membrane fabrication techniques and adsorption technology to develop new water treatment materials and methods for removing pollutants from the environment to combat water scarcity.
This work advancing his proposed endeavor was of great importance because his findings were being used to improve water treatment technology and materials, which is critical for reducing global water scarcity. His work to increase efficiency in water treatment technology has immediate applications in reducing water scarcity.
More specifically, his proposed endeavor also has broad implications for the United States where over 4 million microparticles of plastic are released from municipal wastewater treatment plants each day.
He has also completed at least 6 reviews to date and his work has resulted in 16 peer-reviewed journal articles (11 of them first-authored). Not only this but his work has also gone on to influence his peers. That is, these publications have been cited a total of 777 times.
Furthermore, his study has received funding from the National Natural Science Foundation of China (NSFC), the National Key Technology Research and Development Program of China (NKPRDPC), and the National Basic Research Program of China (NBRPC).
He has also pursued research directly related to his proposed endeavor of developing new water treatment materials and methods to combat water scarcity for 8 years.
Finally, these facts were supported by 2 letters of recommendation collected from other experts who believed that his work was of interest to the U.S.

All of these bits of evidence helped him win the approval of the adjustment committee without an RFE. And his NIW approval came through in just 2 months and 10 days. We are proud of having worked for him and we wish him all the best in his future endeavors.
