Case Summary:

The EB-1B visa is an immigrant visa intended for professors and researchers who are outstanding in their given field, requiring at least 3 years of teaching or research experience within the field. Also, they must be willing to work for an American institution of higher education, or as a researcher for a private employer. The EB-1B also allows the holder to get a green card for themselves, their spouse, and their children under 21 years old.

Our firm was hired to assist in filing for the EB-1B for a principal technical staff from Pakistan. Our team found that the client’s research focuses on current and next-generation wireless networks and radio interface architecture, which addresses some of our nation’s most pressing issues regarding the advancement of reliable, high-quality mobile networks. We have also discovered that our client’s strong background in protocol and algorithm development allowed his research to be particularly original, as our client is also well-known for his development of novel methods to reduce handover failures.

Thus, we concluded that his work would be highly valuable for the advancement of mobile network technology within the United States, and agreed to showcase the significance of his contributions to the advancement of mobile networking. His EB-1B petition packet consisted of the following details:

We noted that he possesses an exceptional record of published works, with 11 peer-reviewed conference articles, 10 of which being first-authored, 1 peer-reviewed journal article, 1 first-authored book chapter, 2 patent application publications, 1 of which was first-authored, and a staggering 1255 granted patents, with 487 of them being first-authored.
Moreover, our client’s work has also been cited 11,943 times at the time of filing, showing that he is a greatly influential figure in his field of research.
In addition, we also have documentation showing that he has conducted at least 24 peer reviews at the time of filing. These records, in addition to the 6 letters of recommendation that he has received from various experts across the world, demonstrate the value he could provide to the United States.

With assistance from the USCIS’s premium processing service, we were able to secure approval for his EB-1B petition in a matter of 6 days. We wish him the best in his future endeavors and thank him for putting his trust in our firm.
