Success Stories: Without Any Request for Evidence (RFE), an Iranian Ph.D. Candidate Working in the Field of Mechanical Engineering Gets I-140 NIW Approval with Our Assistance
Client’s Testimonial:
“Thank you very much for letting me know. Really appreciate it.”
On April 9th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Ph.D. Candidate in the Field of Mechanical Engineering (Approval Notice).
General Field: Mechanical Engineering
Position at the Time of Case Filing: Ph.D. Candidate
Country of Origin: Iran
State of Residence at the Time of Filing: Iowa
Approval Notice Date: April 9th, 2025
Processing Time: 16 months, 20 days
Case Summary:
After assessing the documentary evidence and verifying the testimony, we confirmed that our client holds an M.Sc. in mechanical engineering-energy conversion, and his work focuses on characterizing and analyzing short single-walled carbon nanotubes and micro- and nanoscale materials to optimize materials for energy storage, electronics, heat dissipation, and photon sensing applications.
His research advancing his proposed endeavor is of great importance because:
- His research contributes to optimizing these materials for energy storage, electronics, heat dissipation, and photon sensing, aligning perfectly with the rapidly expanding nanomaterials market and the evolving needs of multiple industries.
- His research is relevant to improving the efficiency and cost-effectiveness of energy storage devices and revolutionizing transportation.
North America Immigration Law Group has an outstanding track record, with over 32,000 visa approvals. When he approached us for assistance in securing his NIW (National Interest Waiver) petition approval, our specialists thoroughly evaluated his credentials and identified key information to strengthen his petition. As a result, we compiled a customized petition packet that included the following:
- Throughout his time working and researching, he has built an impressive record of success, including 8 peer-reviewed journal articles (5 of them first-authored).
- Additionally, he has published his research in top-tier venues, garnering 31 citations. This level of recognition underscores the impact and significance of his contributions within the field.
- Furthermore, he has completed at least 4 reviews to date.
- The U.S. Department of Energy (DOE) and the National Science Foundation (NSF) supported our client’s research. This funding is reserved solely for research directed at advancing the national interest, including studies that address U.S. energy, environmental, and nuclear challenges, promote scientific progress, and advance national prosperity and welfare.
“... in the era of electric vehicles, efficient cooling systems for electronic components are imperative. In the United States, where transportation is a major source of carbon emissions, [client’s[ research aligns with efforts to curb greenhouse gas emissions and fuel consumption. Ultimately, [client’s] work is integral to addressing environmental challenges while advancing automotive technology both on a national and global scale.”
Given his accomplishments and qualifications, our client met the criteria as a professional with an advanced degree. As a result, USCIS approved his NIW petition within 16 months and 20 days without any request for evidence [RFE]. We sincerely appreciate our client’s trust in our law firm and are honored to have contributed to his success.
