On June 23rd, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Senior Development Engineer, BAW R&D in the field of Radio Frequency and Microwave Engineering (Approval Notice).
General Field: Radio Frequency and Microwave Engineering
Position at the Time of Case Filing: Senior Development Engineer, BAW R&D
Country of Origin: Iran
State of Residence at the Time of Filing: Florida
Approval Notice Date: June 23rd, 2026
Processing Time: 9 months, 6 days (Premium Processing Requested)
Case Summary:
The client’s work addresses critical challenges in wireless communication system performance, focusing on the design and optimization of bulk acoustic wave (BAW) radio frequency filters and front-end modules. At the time of filing, she was employed as a senior development engineer, where her work involved radio frequency filter design, multiport antenna modeling, integrated delay control, and prototype validation. Her continued research supports U.S. leadership in semiconductor manufacturing and advances the deployment of high-speed, reliable wireless networks.
Research with National Importance
Her research enhances wireless communication systems essential for high-speed data transmission, critical infrastructure, and emerging technologies. Her contributions to BAW filter design and radio frequency front-end modules improve performance, reliability, and scalability for 5G and beyond, while advancing semiconductor innovation. By developing methods that reduce latency, improve signal integrity, and optimize multiport antenna systems, her work strengthens national capabilities in telecommunications, electronics, and related technology sectors.
Academic Contributions and Recognition
At the time of filing, her record included 4 peer-reviewed journal articles (3 first-authored), 1 first-authored conference article, and 12 citations, with multiple publications in highly ranked journals. She also participated in independent validation of her designs, demonstrating the broader reliance on her work in the field. Her research findings have been referenced by other engineers to guide high-precision radio frequency designs and next-generation communication systems, reflecting the practical and scholarly impact of her contributions.
Expert Endorsements
Recommendation letters submitted with the petition emphasized her recognized expertise in radio frequency engineering, BAW filter design, and multiport antenna systems. The letters highlighted how her work strengthens U.S. technological leadership and supports national priorities in wireless communication.
One recommender noted:
“Her continued presence and contribution to the field, in my opinion, serve the US national interests toward maintaining its dominance in the field of radio frequency and microwave engineering.”
This endorsement shows that her contributions have strategic significance beyond individual projects. Together with her publication record, citation impact, and documented use by independent researchers, the expert support strengthened the petition’s argument that her work is essential to advancing U.S. capabilities in electrical engineering and wireless communications.
NIW Approval and Outlook
The I-140 NIW petition was filed on September 17th, 2025, later upgraded to Premium Processing, and approved on June 23rd, 2026. The approval recognized the national importance of her work in electrical engineering, particularly her research on BAW radio frequency filters, multiport antennas, and high-performance front-end modules for next-generation wireless systems. The petition successfully overcame a prior Request for Evidence (RFE), which required additional clarification of her contributions and their national significance.
This result supports her continued efforts to enhance wireless communications, contribute to semiconductor innovation, and advance high-speed, reliable next-generation networks. We congratulate her on this approval and wish her continued success in advancing U.S. technological leadership in electrical engineering and wireless communications.
