Case Summary:

With a doctorate in chemical engineering and extensive research experience in the field of polymeric membranes, our client—a postdoctoral researcher from India—hired North America Immigration Law Group ( to help him with an EB-1A (Alien of Extraordinary Ability) petition. As soon as we received his request, we assessed his credentials to determine if we could build a strong EB1A case for him. Once confirmed that we could, we counter-signed the retainer agreement.

In order to demonstrate to the USCIS that our client’s research work is cutting-edge and that he has contributed a great deal to the United States, we included the following information in his EB1A petition dossier:

  • A total of 5 recommendation letters signed by distinguished figures in the field of chemical engineering were used to bolster our client’s case. According to one of these experts: “As he has already shown his capabilities in chemical engineering and his contributions to polymeric membranes development , it is clear his ongoing work will be just as important as his past.” These letters acknowledged our client’s “remarkable” contributions when it comes to the improvement of US healthcare.
  • At the time of filing, our client had already published 17 peer-reviewed scientific articles and conference articles. This productive and exemplary authorship record strengthened his case to a great extent.
  • We highlighted the 275 times his work had been cited by his peers and the 30 reviews he had conducted for high impact journals.
  • Apart from our client’s excellent educational qualifications, we detailed his stellar research focused on the development of new polymeric membranes for various separation applications. His work addresses many pertinent issues, such as how to produce membranes with desired physical characteristics to be used in water desalination, waste treatment, protein separation and other applications. The incorporation of all this information led to our main line of argument: that his continued presence in the United States will advance the field of chemical engineering and polymeric membranes to a great extent and that he is an asset to the nation.

NAILG’s unwavering commitment led our client to EB-1A victory. Five months after filing, our client opted to upgrade his case to Premium Processing. Just 9 days later, an approval was issued. We are thankful to our client for giving us the opportunity to represent his EB-1A petition, and we congratulate him for overcoming the first milestone in the green card process.
