“Thank you for helping me get my NIW and EB-1A cases approved. I am very grateful for working with you. I am also happy to have chosen your team as my attorney.”

Case Summary:    

Before his EB1A petition was approved, our client had already entrusted the North America Immigration Law Group (NAILG) with the filing of his National Interest Waiver (NIW) case, an effort that showcased his groundbreaking research in power electronics and renewable energy systems. His longstanding commitment to advancing efficient energy conversion technologies and power regulation mechanisms positioned him as an influential voice in the field of electrical engineering.

His work has addressed key challenges in optimizing the performance of grid-connected inverters, multi-level inverters, and DC-DC converters – technologies that are vital to improving the reliability, scalability, and sustainability of modern power infrastructure. His innovations include:

➢ Enhancing the efficiency of power conversion in solar energy systems,

➢ Reducing voltage stress on power electronic switches, and

➢ Improving inverter system performance to support clean, resilient energy networks.

In preparing his NIW and EB1A petitions, NAILG highlighted the national implications of these contributions, particularly in light of the United States’ increasing investment in renewable energy and efforts to reduce dependency on traditional grid sources. His work speaks directly to urgent national priorities like peak energy management, environmental sustainability, and commercial energy efficiency.

Backed by funding from respected institutions such as the Villum Foundation and the Estonian Research Council, our client’s record includes:

➔ 67 peer-reviewed journal articles

➔ 1,961 citations, placing him in the top 1% of highly cited engineering authors worldwide

➔ Over 50 reviews completed for academic journals, affirming his leadership and expertise in the field.

His influence is further reflected in the words of an independent expert:

“[Client] has endeavored to tackle the issues that plague DC-DC converters used for solar energy production and storage. His converters markedly improve the voltage of electricity produced by photovoltaics, resulting in better performance and efficiency. [Client]’s work has made the widespread adoption of solar energy platforms more feasible. Due to the meritorious nature of his novel power converters, the United States can ill afford to ignore his research. It is necessary that he is granted an opportunity to continue his work.”

While his EB1A petition, also filed with NAILG, was ultimately approved first, his NIW approval is a meaningful recognition of the foundational significance of his research. Together, these dual approvals affirm that his work is not only of extraordinary ability but also squarely aligned with the national interest.
