Case Summary:

North America Immigration Law Group ( is a leading US immigration law firm specializing in employment-based immigration petitions. We work diligently to help all our clients turn their US permanent residency dreams into reality. Recently, we were approached by a postdoctoral fellow from China in the field of microbiology to spearhead his EB-1A (Alien of Extraordinary Ability) petition. We meticulously put together a strong case on his behalf and successfully helped him secure an approval just 8 days after filing.

We believe that the cornerstone of our client’s EB-1A petition success was the right presentation of his accomplishments to the USCIS. We showcased his competitive position in the scientific community by detailing his strong background in biotechnology, microbiology, virology, and immunology. We also demonstrated how his laudable research ideas have led to significant advances in the microbiology discipline—his work is particularly focused on the elucidation of the viral and infectious mechanisms responsible for the host’s immune response to viruses.

Additionally, we detailed his extraordinary achievements, including his 14 peer-reviewed scientific articles and the nearly two dozen peer-reviews he had conducted for high-impact scientific journals. To show that his profound research has received recognition from the scientific community, we included his citation record which accounts to at least 181 citations from top-researchers around the world.

In order to uphold our client’s petition, we also incorporated recommendation letters from several industry experts. One of his recommenders added the following statement about him in his letter: “[Client] has all the on-paper qualifications that one would expect of a scientist who has made important contributions to the field. What distinguishes [Client] from other scientists with similar credentials, however, is his deep insight into the world of virology…

Thanks to Premium Processing (PP), the entire adjudication process was expedited and the eagerly awaited EB-1A petition approval came just 8 days after filing. We congratulate our client on reaching the first milestone in the two-part green card process, and we wish him the best as he continues to drive more innovations in the field of microbiology.
