Case Summary:

North America Immigration Law Group has attained a leading position in the field of obtaining immigrant and nonimmigrant visas for petitioners. Our clients hail from all over the world and are experts in every walk of life imaginable. This experience with over 25,000 clients has given us an edge over other law firms when it comes to the ins and outs of the adjudication process. We help our clients right from the first step of case preparation all the way through the processing and approval. This is why we receive positive feedback from our clients all the time.

A client came to us in February 2022 for his Alien of Extraordinary Ability (EB1-A) petition. He was one of the few leading biosensors experts in analytical chemistry. He was especially well-known for his works in nanomaterials based sensors. This initial information about his proposed work itself was enough to show that he was an extraordinary researcher in the field. Our team ensured that even the adjudicators knew this for a fact by personalizing his petition with the following details:

  • The field has recognized his authority by inviting him to review and evaluate the work of his peers no fewer than 48 times.
  • He has actively engaged his peers in the field of analytical chemistry by authoring and co-authoring 15 peer-reviewed articles that have been published in international journals.
  • In fact, he is one of the top 1% of most highly cited authors publishing on topics in chemistry with over 482 citations, over the past 10 years according to Microsoft Academic.
  • His publications have been cited by researchers in at least 26 countries according to Google Scholar.
  • His work has thus been among the most cited in the field in the past several years, and he has been consistently cited more than one would expect from an average researcher in the field. It can therefore be objectively corroborated that he has made significant original contributions documented by his publications, as his achievements have been widely recognized and relied upon in the field of analytical chemistry.
  • Due to its clear implications for cancer diagnosis and therapy, his research has already attracted the attention of the private sector.
  • Furthermore, his work has resulted in the publication of two patents. He has published two patents based on his work on biosensors and their applications in cancer imaging. The publication of these patents demonstrates how his research is resulting in unique work that has value for the private sector.
  • We also encouraged our client to obtain written testimonials from other experts in his field who could corroborate the information we were putting down in the petition. One of these said:

“[The client] is currently a leading researcher in the field of analytical chemistry and a most valuable part of the scientific community. He has consistently introduced cutting-edge methodologies and technologies into the field, which have not only influenced his peers but have also changed the character of analytical chemistry globally. Any interruption to his work in the United States would undoubtedly hinder his field’s growth and maturation.”

These pieces of evidence when put together made for a very impressive petition, winning him the EB1-A approval in just 1 month and 11 days. Thanks to the premium processing upgrade for speeding up the adjudication process.
