Case Summary:

Our client, a research associate from Ghana, has an impressive research portfolio that focuses on the growth of viable solar energy devices for the booming renewable energy global market. His studies have led to more efficient solar technology components, which has encouraged an increase in the amount of power being generated by solar technology. Noting the importance of his achievements, one of our client’s peers had this to say about his work:

…it is extremely practical for decreasing the United States’ oil dependence. Because his work is helping to improve the energy conversion efficiency of solar cells, he is promoting the widespread adoption of solar power generation in the United States.”

He was not alone in this show of support and was joined by several other nanoengineering experts, all of whom contributed recommendation letters to advocate the approval of our client’s EB-2 NIW (National Interest Waiver) case. We have no doubt that their letters lent a hand in case approval.

Besides the recommendation letters mentioned above, our client’s NIW petition dossier also contained information on his 4 peer reviewed journal articles, the 207 times his work was cited, and the 1 peer-review that he had conducted for a well-known scientific journal.

After months of hard work, we submitted our client’s comprehensive NIW petition packet to the USCIS and waited for them to adjudicate it based on the Matter of Dhanasar. As we were able to successfully prove that our client’s work substantially benefits the energy sector of the United States, he was granted the national interest waiver just 2 months and 10 days after filing. We congratulate our client on this win and thank him for working with us. To learn more about the Matter of Dhanasar, please visit
