Client’s Testimonial:

“I cannot thank Chen enough. They have been super helpful while preparing the petition. Whenever I had any doubts, I used to message them through their system and they replied in a quick manner with detailed guidelines. They wrote an overall good petition package. Even after the submission of the petition, I had a few questions regarding the NIW issues; they were always so responsive and guided me in the best manner, helping me keep myself calm in this journey. I appreciate their help and will always recommend other NIW pathtakers to Chen without hesitation. Thank you.”

On March 31^st, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Research Associate in the Field of Mechanical and Energy Engineering (Approval Notice).

General Field: Mechanical and Energy Engineering

Position at the Time of Case Filing: Research Associate

Country of Origin: Bangladesh

Approval Notice Date: March 31^st, 2025

Processing Time: 13 months, 15 days (Premium Processing Upgrade Requested)

Case Summary:

We are pleased to share the success story of a mechanical engineer whose I-140 NIW (National Interest Waiver) petition was approved after 13 months and 15 days, following an upgrade to premium processing. This outcome highlights the value of impactful contributions in energy systems and the growing importance of sustainable engineering to U.S. national interests.

Our client holds a Ph.D. in mechanical engineering and is currently employed as an Energy & Sustainability Lead in a company. His proposed endeavor centers on integrating experimental and computational modeling with advanced data analysis methods to optimize renewable and clean energy systems. This research directly supports the decarbonization of residential, commercial, and industrial sectors and addresses urgent national priorities in energy sustainability and climate resilience.

1 accepted peer-reviewed conference paper,
A total of 29 citations as per Google Scholar,
At least 5 completed peer reviews.

The petition emphasized how his work contributes to improving wind turbine performance, renewable energy storage systems, and demand-side energy efficiency. His study on flexible blade configurations in vertical-axis wind turbines, for instance, offered insights into passive blade morphing for enhanced aerodynamic performance. Another notable project modeled borehole thermal energy storage systems integrated with concentrated solar power, demonstrating improved energy density and heat transfer over traditional storage systems.

We also highlighted that the client’s research has been supported by competitive funding from the U.S. Department of Energy, reinforcing its significance in advancing national objectives in clean energy.

To further validate the petition, 2 letters of recommendation from respected scholars in mechanical and energy engineering were submitted. These letters affirmed the originality and impact of his work and its importance to ongoing national sustainability efforts.

“[Client’s] extensive record of achievements, in addition to his active peer review service, unequivocally establishes the indispensability of his mechanical and energy engineering research to the advancement of renewable energy integration, grid modernization, and low-carbon technologies in the U.S. and globally.”

With a focused petition demonstrating the scientific merit and practical importance of his work, NAILG successfully secured a favorable outcome for this exceptional engineer.
