Case Summary:

Equipped with an M.S. degree in computer science, a senior machine learning engineer from India contacted North America Immigration Law Group ( to help him file an EB-1B (Outstanding Professors and Researchers) petition. He had garnered his employer’s full support as this is an employer-based petition. After his employer provided us with the relevant documents required to build our client’s case, our team instantly started preparing a strong EB-1B case for him. Here are the chosen bits of information that we included in the petition packet:

  • Research Brief: To prove to the USCIS that our client’s work is essential in the United States, we commenced by reviewing his research on developing machine learning and pattern recognition algorithms that identify and recognize objects and designing multi-spectral computer vision optical systems. We established that his research addresses some of our nation’s most pressing issues in understanding iris recognition systems and object recognition. His strong background in computer science has allowed his research to be particularly original, with applications such as aquaculture, iris scanning technology, and biometric identification tools.
  • Peer Review Experience: At the time of filing, our client had already participated in 7 reviews of highly acclaimed journals and conferences. This remarkable record demonstrates his extraordinary abilities as a leading researcher in the field of computer science.
  • Citation and Publication Count: Thanks to Google Scholar reference, we ascertained that our client’s 3 peer-reviewed scientific articles, 1 book chapter, and 2 granted patents – a productive and exemplary record gathered 148 citations, thereby purporting the major significance of his work.
  • Testimonials: To fortify our client’s EB-1B petition further, we incorporated four recommendation letters signed by fellow experts in the field who were familiar with his work. One of them asserted,

“The work of [client] is among the most impressive in our field of computer science due to its innovative improvements of commonly utilized security technologies. Because of its benefits for governmental, military, and consumer applications, it is essential that he should be permitted to continue his work in the United States without interruption.”

Thanks to the Premium Processing Service, our client’s case was adjudicated in just 9 days. PP is a paid option offered by the USCIS that allows petitioners to enjoy quickened adjudication (the case will be processed within 15 days instead of 9-12 months). We congratulate our client for achieving an EB-1B petition approval and thank him for entrusting us with his case.
