Case Summary:

An Iranian research scientist hired North America Immigration Law Group (NAILG) to help him obtain an O1-A (Individuals with Extraordinary Ability or Achievement) visa. Our vast experience dealing with employment-based visa petitions allow us to gather reliable statistics of the most up to date adjudication trends. With our help, our client received his approval notice in a short span of 10 days.

During our initial evaluation, our team conducted a thorough review of our client’s credentials to verify his chances of O1-A approval. Our client has a master’s degree in Analytical Chemistry and his unique research work has greatly contributed to the clinical trials for gene and muscular dystrophy therapy, healthcare, pharmaceuticals, as well as the oil and gas industry for alleviating environmental pollution and its concerns. One of his most prominent research works involves the use of Polymeric Ionic-Liquid-based sorbent coatings to address organic pollutants in water, which is key to monitoring and assessing water quality.

Our client’s O1-A petition packet also detailed his publication and citation record. At the time of filing, he has published 3 peer-reviewed scientific articles and 1 published patent application which have accumulated 62 citations. He has also been invited to conduct 4 reviews for highly acclaimed journal in his field. Our team carefully investigated in the citations he received, and found out that his publication records have positioned him in the top 10% by citations for his field and year. We have also included 6 recommendation letters in the petition packet, all of which discussed the impact of his works on the research community.

After months of working closely with our client, we successfully demonstrated that our client had satisfied the O1A criteria. We congratulate him for the O-1A approval, and we wish him the best as he continues his research in the field of Analytical Chemistry in the US.
