Client’s Testimonial:

“Thank you very much for letting me know this good news. And thank you very much for all your help with my EB1A application. Your law firm is very professional and good at the case preparation. I will definitely recommend your law firm to my friends and my community, in fact I have done this.”

On January 12th, 2018, we received another EB-1A (Alien of Extraordinary Ability) approval for a Postdoctoral Fellow in the Field of Chemical Engineering (Approval Notice).

General Field: Chemical Engineering

Position at the Time of Case Filing: Postdoctoral Fellow

Country of Origin: China

State of Residence at the Time of Filing: California

Approval Notice Date: January 12th, 2018

Processing Time: 10 Days (Premium Processing Requested)

“The North America drug delivery market, largely controlled by the U.S., is expected to be worth $823 billion by the year 2024. [Client’s] efforts affect basic drug delivery developments, thus sustaining the nation’s success and leadership in this lucrative market.”

“Clearly, [Client] has proven to be a leader in his field, a status that is only reinforced by the influence of his research contributions. It is thus evident that any interruption to his continuing efforts would be detrimental to progress in the field.”

The quotes above were extracted from recommendation letters signed by well-known chemical engineers. Overall, there were 6 letters, all of which supported the approval of our client’s EB-1A (Alien of Extraordinary Ability) petition. These letters played a big role in convincing the USCIS that our client deserved to get one step closer to US permanent residency.

Our firm, North America Immigration Law Group (NAILG), was responsible for putting together a strong EB1A petition for our client (a postdoctoral fellow from China). Besides the aforementioned letters, our client’s petition dossier contained details of his research on colloid and interface science. It also listed the 146 times his 7 published articles were cited and the 16 times he judged the work of his peers.

In a nutshell, all the information contained in the petition packet supported our argument that our client’s work addresses some of our nation’s most pressing issues in engineering micro-to-nanoscale devices and nanostructured materials by electric-field-assisted assembly of colloids. Additional information such as a copy of his doctoral degree, CV, and employment letter served as additional evidence that our client is among the most influential individuals in the field of chemical engineering.

We congratulate him for securing EB1A petition approval in just 10 days, and we thank him for choosing us to help him adjust his status for permanent residence (filing an I-485 application).
