Success Stories: EB-1A Petition Approved for Postdoctoral Researcher in California in the Field of Medical Biochemistry


Client’s Testimonial:

“First I would really like to thank you heartily for all the help in this case, without which this approval would not have happened. Even much before my case was submitted, I was so impressed by your service that I had already recommended your firm to two of my friend […] In addition, two of my friends who will be ready to file for their application in a year, have almost made up their mind to work with your firm. Nevertheless, be assured that I will continue spreading about your firm to all my friends and colleagues who might need help to file their petition.”

On March 7th, 2016, we received another EB-1A (Alien of Extraordinary Ability) approval for a Postdoctoral Researcher in the Field of Medical Biochemistry (Approval Notice).


General Field: Medical Biochemistry

Position at the Time of Case Filing: Postdoctoral Researcher

Country of Origin: India

Service Center: Nebraska Service Center (NSC)

State of Residence at the Time of Filing: California

Approval Notice Date: March 7th, 2016

Case Summary:

North America Immigration Law Group ( had the pleasure of working with a talented postdoctoral researcher working in the field of medical biochemistry. Because our client elected to file his case under Premium Processing, he received an approval notice from Nebraska Service Center less than three weeks after we filed the case on his behalf (regular processing takes between 4-9 months).

Client’s Credentials:

Our client earned his M.Sc. and Ph.D. in Chemistry from a top research institution in his birth country of India. His professional record is just as impressive as his academic background and is partly made up of 22 published journal papers that have collected 300 citations. Our client also sits on the editorial board of two scientific periodicals and has conducted peer reviews for multiple journals. Our legal team argued that his work on discovering the molecular underpinnings of complex human diseases that are caused by protein malfunctions—such as Alzheimer’s disease and Hypertrophic Cardiomyopathy—advances several sectors in the United States.

Our client’s medical biochemical accomplishments were verified by other influential researchers in the field through firm recommendation letters. When our client asked these scientists to support his EB-1A petition, five agreed to lend a hand. Their letters played a role in persuading the USCIS that the field would not progress as quickly as it has without our client’s insights. One of these experts wrote, “[Client’s] national and international research appointments point to the attention that his work has garnered around the world, as well as the global utility of his work. It would be a mistake to rid your country of such a diversely experienced and sought after researcher.”  

Final Step:

Our client chose to file his EB-1A petition and I-485 application (final step in the green card process) concurrently. We congratulate him on his petition approval and join him as he awaits favorable news from Nebraska Service Center regarding his I-485 application.
