Client’s Testimonial:

“Thank you so much for your support and assistance! I truly appreciate all the efforts you’ve put into my case.”

Recently, we received another EB-1A (Alien of Extraordinary Ability) approval for a Postdoctoral Fellow in the Environmental Engineering field (Approval Notice).

General Field: Environmental Engineering

Position at the Time of Case Filing: Postdoctoral Fellow

Country of Origin: China

Approval Notice Year: 2024

Processing Time: 12 days (Premium Processing Requested)

Case Summary:

Following the implementation of strict criteria by USCIS for qualifying as an Alien of Extraordinary Ability under the EB-1A program, applicants must showcase the significance of their work and its potential benefits to the United States. If a petitioner is not familiar with the system, this process can be tedious and time-consuming. The North America Immigration Law Group can assist in these circumstances, helping clients worldwide understand the latest trends and ensuring their success.

When a client from China approached us for assistance with her EB-1A application, we found that she possesses a Ph.D. in Earth and Atmospheric Science, indicating that she has an advanced degree. Her research focuses on advancing air quality and toxicological responses, specifically aiming to improve biogenic emission models for ozone simulations. We gathered her credentials and achievements into the petition packet to secure the approval:

Our client described her research successes in 11 peer-reviewed journal articles (5 firstauthored), 8 conference abstracts (5 first-authored), and 1 preprint that have been published in international journals.
Her publications are cited more than 122 times in at least 31 countries.
Our client has conducted at least 25 reviews for journals, proving that our client is reliable in upholding integrity and maintaining the quality of the papers.
Our client’s extraordinary ability in the field is additionally reflected by her significant contributions to research funded by the National Key R&D Program of China, the National Natural Science Foundation of China and many other reputable institutions. It shows that the study done by our client is significant and aligns with the values of these organizations.

We have also included recommendation letters from experts to further support her petition:

“It is sufficiently evident that {client} skillset and contribution to her field are irreplaceable and highly desirable in the US and around the world. It is, therefore, my sincere pleasure to support the uninterrupted continuation of her valuable research in the US.”

With the assistance of detailed documentation, Premium Processing, and our team’s systematic case preparation, she successfully secured EB-1A approval in just 12 days. We value her continued support and look forward to more positive outcomes from her research.
