Client’s Testimonial:

“I am very satisfied with your service. Thank you so much!”

On May 14th, 2021 and August 22nd, 2021, we received another EB-1A (Alien of Extraordinary Ability) and EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Scholar in the Field of Environmental Engineering (Approval Notice).

General Field: Environmental Engineering

Position at the Time of Case Filing: Postdoctoral Scholar

Country of Origin: China

Approval Notice Date: May 14th, 2021 (EB-1A) and August 22nd, 2021 (NIW)

Processing Time: 15 days (EB-1A) (Premium Processing Requested) and 10 months, 9 days (NIW)

Case Summary:

We are delighted that our client received her NIW & EB-1A approvals 3 months apart.

Our client approached us initially to help her file an EB-2 NIW (National Interest Waiver) petition and in a gap of 2 months retained our services for filing another petition under EB-1A (Alien of Extraordinary Ability) petition back in 2020. USCIS took a good amount of time to adjudicate her cases and since it was taking a long time, our client upgraded her EB1A case to Premium Processing Service, which is a paid option offered by the USCIS that allows petitioners to enjoy accelerated adjudication (the case will be processed within 15 days instead of 9-12 months). Thus, she received her EB1A case approval in just 15 days after we submitted her premium processing request.

North America Immigration Law Group is reputed for handling employment-based visa petitions to help the petitioners to get closer to receiving their green cards. In these NIW and EB-1A cases, we conquered the complex green card process by devising a unique petition packet including the following successes of our client:

We noted that she held a Ph.D. in environmental engineering, researching environmental and energy processes, and is regarded as an authority in the field. We concluded that her research addresses some of our nation’s most pressing issues in energy and the environment. Her study on this topic has been widely published in top-ranked journals and cited by research groups across the globe.

Consequently, we highlighted the 625 citations gathered from 20 peer-reviewed articles she published. These articles have been published in some of the noteworthy journals in her field and have been cited by a long list of researchers who have implemented her conclusions to improve the quality of their work from at least 43 countries, proving how very few other environmental engineers have matched her citation record, which reflects her unique skill set and ability to thoroughly address areas of improvement within her field. Besides, we observed that she had also conducted 55 reviews for highly acclaimed journals. Thus, we confirmed her remarkable peer-review contribution to the scientific community as a judge of the work of others.

Before submitting her case to USCIS, we also added four recommendation letters that were imperative for us to sustain her case further. Our client’s remarkable influence in the field is discussed more by her fellow experts, confirming that she is completely committed to using her talent to solve environmental and energy challenges and is in an elite class of scientists with the aptitude to do so.

Just like several other petitioners who filed more than one petition to get closer to obtaining the green card, our client also overcame this challenging process and received both I-140 petition approvals. We thank her for trusting us and with her I-140 applications and now awaiting her I-485 approval with us.
