Posted by wegreened on March 11, 2023 in NIW, Physics (Engineering Physics, Nuclear Engineering, Biophysics, Optics, Photonics, Plasma)

Client’s Testimonial:

“I am also happy to know that my I-140 has been approved recently. Thank you so much for making it happen.”

On January 8^th, 2023, we received another EB-2 NIW (National Interest Waiver) approval for a Visiting Assistant Professor in the Field of Physics (Approval Notice).

General Field: Physics

Position at the Time of Case Filing: Visiting Assistant Professor

Country of Origin: Nepal

State of Residence at the Time of Filing: Illinois

Approval Notice Date: January 8^th, 2023

Processing Time: 2 months, 12 days

Case Summary:

The following data was collected as evidence for a client from Nepal who wanted to apply for an NIW (National Interest Waiver) approval from his academic and professional documents:

As an expert in the field of physics, his proposed endeavor is to continue his research on the optimization of state-of-the-art materials characterization techniques to analyze lead-free, highly stable luminescent metal halide perovskites to advance optoelectronic applications such as photovoltaic cells and light-emitting diodes.
This proposed endeavor also has broad implications for the United States, since moving away from traditional lighting sources such as filament and fluorescent bulbs and developing sustainable, renewable, economical lighting sources is a key strategy for meeting the greenhouse gas emission goals set by the federal government and the Paris Agreement.
At the same time due to its clear national importance, his research has in fact been supported with funding from the National Science Foundation (NSF), and the National Natural Science Foundation of China.
His 5 years of work analyzing luminescent metal halide perovskites to advance optoelectronic applications has given him immense expertise. Due to this, he has been invited to conduct at least 1 review.
He has also published 13 peer-reviewed journal articles (4 of them first-authored) and has been cited a total of 269 times according to Google Scholar.
He also found support from 4 other experts who wrote letters that buttressed the petition we had been writing. One of these experts wrote:

“[The client’s] research is advantageous to the United States research community, particularly with regard to its environmental goals. [The client’s] work advances this goal through his optimization of WLED structures, expanding the efficiency and efficacy of this technology. Further investment in [the client’s] physics research is therefore in the best interests of the United States.”

So, when we filed his petition, we were already certain that his case would win the approval from the USCIS, as we had worked our best to gather every relevant evidence of his valuable work for the country. Thus, the approval of his case in 2 months and 14 days was a pleasant development. We wish him all the best in his future endeavors.
