General Field: Environmental Sciences

Position at the Time of Case Filing: Research Assistant

Country of Origin: Nepal

State of Residence at the Time of Filing: Oklahoma

Approval Notice Date: February 19th, 2020

Processing Time: 14 months

Case Summary:

A Research Assistant in the field of environmental sciences reached out to North America Immigration Law Group ( to file an EB-2 NIW (National Interest Waiver) petition on his behalf. Thanks to our experience of securing over 16,000 I-140 approvals, we determined that he was a good fit for this category after reviewing his CV and credentials. We worked with our client carefully and presented his various achievements to the USCIS in a clear and concise manner.

Our client’s research focuses on developing sustainable energy resources using biomass and biofuels. His work in this area is of great importance because it opens avenues for the use of cheap and environmentally friendly biofuels as an alternative energy source to conventional and pollutive fossil fuels.

To support our argument that our client merits a national interest waiver, we submitted evidence of his impressive publication. At the time we filed his case, our client has published 11 peer-reviewed journal articles (3 of them first-authored) and 4 conference papers (2 of them first-authored) and collected 45 citations; thereby demonstrating that these publications are widely recognized and relied upon in the field of environmental sciences. We incorporated the related material into his petition letter, and provided in-depth analysis to show the merit of our client’s endeavor.

6 letters of recommendation were included into the petition packet in support of our client’s case. One of the recommenders stated “[Client’s] contributions play a vital role in commercializing the commonplace use of biofuels, as his findings have shown that not only can biofuel production become more efficient in yield, it is also possible to reduce costs. His work will only continue to show stronger results for the industry, and the United States should not pass up the opportunity to welcome one of the strongest researchers I have personally known.”

Besides the service request that we raised on our client’s behalf after the case went beyond the average processing time, everything about our client’s EB-2 NIW case was smooth sailing. We congratulate him on this milestone, and wish him the best with his I-485 application. Seeing that the I-485 application is the final leg of the green card journey, an approval means finally obtaining a green card.
