General Field: Wireless Communications

Position at the Time of Case Filing: Senior Technical Staff

Country of Origin: South Korea

State of Residence at the Time of Filing: Virginia

Approval Notice Date: February 6th, 2023

Processing Time: 2 months, 5 days

Case Summary:

When a senior technical staff in wireless communications from the Republic of Korea approached to hire our services for his National Interest Waiver (I-140 NIW) approval, we did not know that we were embarking on a long and productive journey with him. Incidentally, he needed to retain our services for his O1-A (Individuals with Extraordinary Ability or Achievements) as well as H1-B (Temporary Workers) visa. So as is customary with our team, we began after countersigning the retainer with him and began to look into his credentials. Once we had enough evidence for his EB2-NIW petition letter, we began putting them together. Some of the relevant information that we gathered are as follows:

  • His proposed endeavor was to continue his research on developing a 6G cellular communication system to improve wireless communications.
  • His research endeavor was of great importance because it leads to progress in communications technology, which has economic benefits.
  • He has been a driving force in advancements in the areas of wireless communications and 5G, which is why one of his recommenders wrote the following testimonial about him:

“[The client] has worked closely on the development of 5G New Radio protocol and in doing so has brought the advent of widespread 5G cellular signaling noticeably closer. [Client’s] research is therefore of inherent merit.”

  • His proposed endeavor also has broad implications for the United States, where wireless communications and the use of 5G are primarily conducted through smartphones today. According to experts, over 290 million Americans will use a smartphone in 2020, and this number is expected to rise in the coming years, which indicates that wireless communications, and by extension his work, is important to the American people. As another recommender said:

“[The client] has used his expertise in wireless communication to enable ProSe to function more efficiently, with reduced signal interference and lower power costs. Doing so places him and his work directly in line with the best interests of the American wireless communications sphere. I therefore fully recommend that the U.S. retain [the client’s] expertise.”

  • On the other hand, he has also completed at least 13 reviews to date and his work has been published as 1 peer-reviewed, first-authored journal article, 4 peer-reviewed conference articles (2 of them first-authored), and 45 United States patents.
  • These publications have also been cited a total of 363 times according to Google Scholar.
  • Along with this, he has also made a breakthrough in V2X communication by addressing edge-of-network signal strength and the effective use of radio resources. His work on cellular-based V2X communication is unique in the field because it involved developing a communication base station coordination method.
  • Not only this, but he has been pursuing research directly related to his proposed endeavor of developing a 6G cellular communication system for 10 years, giving him excellent command over his area of expertise.
  • This is why he could easily obtain 4 letters of recognition, two each from dependent and independent experts in his area of work.

These factors played a major role in his case approval. Good case preparation is singularly important for the successful adjudication of any case. This is what our team makes possible for every client including the present one. We congratulate our client on his victory and thank him for choosing our firm to represent him.
