Case Summary:

North America Immigration Law Group has prepared relevant materials for our client, a guest researcher from Brazil to show his accomplishments in his chosen field of metrology, and successfully helped the applicant to complete his EB2-NIW application:

  • 12 peer-reviewed journal articles (4 of them first-authored), 10 conference articles (2 of them first-authored), and 2 books (1 of them first-authored) published in highly ranked peer-reviewed journals.
  • According to Google Scholar, his publications have been cited a total of 51 times.
  • Due to his knowledge and expertise, he has been regularly invited to conduct peer reviews for authoritative journals and conferences in the field. He has conducted at least 4 reviews to date.
  • Furthermore, we documented that his research has been financially reinforced by well-known institutions, demonstrating his capability to continue his work in the United States successfully. The allowance he received includes grants from the Inter-American Development Bank through the Interamerican System of Metrology, indicating the relevance and significance of his research on a national level.

We also added four letters of recommendation obtained from his fellow experts in the field corroborating the great importance of his research endeavor because it drives innovation across a multitude of industries. Therefore, we discussed his groundbreaking research in the field of metrology, focusing on thermometry and magnetic particle imaging (MPI) to progress the development of better and more efficient MPI reconstruction algorithms and to create new temperature measurement techniques and standards.

Therefore, based on his achievements and the above prerequisites, our client is eligible to become a professional member holding a higher degree. As a result, he was approved by the USCIS and received his NIW approval in just 7 days without receiving a supplementary document [RFE]. We thank him for his continued trust in us. We are appreciative of the chance to work with him and honored to have helped him succeed.
