General Field: Nanotechnology

Position at the Time of Case Filing: Postdoctoral Researcher

State of Residence at the Time of Filing: Illinois

Approval Notice Date: April 8th, 2016

Case Summary:

Merely a week after North America Immigration Law Group ( filed an EB-1A (Alien of Extraordinary Ability) petition on our client’s behalf, he received notification of case approval. The speedy adjudication is largely thanks to Premium Processing.

What is Premium Processing (PP)?

PP is an add-on option offered by the USCIS. All petitioners have to do is submit an I-907 form and pay the USCIS an additional $1,225. They can then take advantage of accelerated adjudication, which means that action will be taken on their petitions within 15 days instead of the usual 4-9 months. The only catch is that not all petitioners qualify for PP, only those whose petitions are submitted under specific visa categories (EB-1A is one of them).

Qualifying for EB-1A:

It is no secret that EB-1A is upheld by a very high standard of law and that it has the lowest approval rates. Only petitioners who have risen to the very top of their field with national or international acclaim can file their I-140 petitions under EB-1A. As our client boasts an impressive educational and professional background, he qualified for EB-1A. His petition detailed his 18 papers, 8 book chapters, and over 40 conference papers. Additionally, we listed the 409 citations to his work and the 40 times he conducted peer reviews for some of the most prominent scientific journals in the field of nanotechnology.

Securing Recommendation Letters:

Our comprehensive legal services also included helping our client select other experts in the field who qualified to serve as his recommenders. The five shortlisted experts whom our client contacted agreed to support his EB-1A petition by signing strong recommendation letters. Here are several quotes extracted from these letters:

“As you can see from his research and demonstrated level of international influence through his publications and peer review service, it is apparent that [Client] is a leading figure within the nanotechnology and nanorobotics field. His prior successes clearly indicate that he will continue to make impressive advancements in this area to the great benefit of the United States.”

“To conclude, it is clear to me that [Client] is an asset to the scientific community in the United States. His significant research accomplishments are and will continue to provide tangible benefits to the advancement of nanotechnology, especially in medicine. I am confident in [Client’s] ability to continue to contribute to the growth of this exciting field.”

“Based on [Client’s] excellence in this project, his first-class education, and his continued academic support of his peers, he has achieved a place of authority in nanotechnology research and has established himself at the top of his field.”

Celebrating Petition Approval:

We congratulate our client for obtaining a highly sought-after EB-1A petition approval. This approval serves as yet another example of our law firm’s commitment to helping every client accomplish their goal of getting closer to a green card. Our client is embarking on the final leg of the green card journey with the help of our D.I.Y. Packet. It contains guidelines on how to properly put together an I-485 application. We wish him the best with this and look forward to updates.
