Approval Notice Date: September 7th, 2021 (O1-A) and December 2nd, 2021 (EB1A)

Case Summary:

A principal scientist based in India hired North America Immigration Law Group to help him obtain an O1-A (Individuals with Extraordinary Ability or Achievement) petition approval. Our law firm is well established for filing employment-based visa petitions uniquely which helps our clients to secure their ultimate goal; their green cards. Thus, before we began to prepare his O1A petition packet, we evaluated his credentials, therefore, we were certain that he would get the O1A approval. After 3 months of his O1A approval, our client retained us for another petition under the EB-1A (Alien of Extraordinary Ability) visa category. Normally, the O-1A visa is easier and quicker to get than an EB-1A green card. However, we helped our client to achieve both O-1A and EB1A approvals back-to-back in the gap of 3 months. We made sure to file a successful application in each category.

As we are aware that the O-1A visa is for individuals who have achieved national or international acclaim and have risen to the top of their field in the areas of science. The EB-1A enables individuals who have achieved substantial international or national success in their field due to their extraordinary talent to live permanently in the U.S. Since our client already held the O1A approval, it became way easier to obtain the EB1A success.

Here is the synopsis of his O1-A and EB-1A petition packets, containing the following details:

  • We briefed his research focusing on the development of silver nanowires, addressing some of our nation’s criticalities in understanding the underlying mechanisms of complex materials. Thus, his potent background in polymeric biomaterials science and engineering has enabled his research to be particularly successful, confirming him as a consistently productive researcher and among the top minds in the field of nanoscience today.
  • We incorporated his noteworthy publication and citation record; the 17 peer-reviewed scientific articles, two book chapters, and one monograph he published in top journals in the field. We concluded that peers have taken ample notice of our client’s work, having seen fit to cite it 1,386 times from 70 countries, this serves as a testament to its high quality and relevance to ongoing research.
  • Also, our client’s research is important for his field. He has established himself further in the field of nanoscience as a prolific peer reviewer. He has conducted 20 peer reviews for several journals, deducing his high regard as an authority in his field.
  • Moreover, we attached 4 recommendation letters provided by our client obtained from other experts in the field to establish that our client is at the forefront of the field of nanoscience as is demonstrated by this consistent record of success and his myriad professional accomplishments. One of the recommenders signed to:

“Considering his unparalleled success in the field of nanoscience thus far, I believe it is in the best interests of the scientific community and the United States that [client] be permitted to continue his research unimpeded.”

We’re delighted that our client found us, and we were able to help him secure the EB1A approval. Both O1A and EB-1A petitions are eligible for premium processing, which allows USCIS to decide on the filed petition within 15 days (whether it is “calendar” days or “business” days). Therefore, the O1-A case took 14 days to get approved after we filed his case. That said, the EB-1A has one of the shortest USCIS processing times, compared to other employment-based green cards. We are extremely happy that he successfully achieved his EB1A approval in just 9 days. We thank him for choosing our law firm to file his I-129 and I-140 petitions and again signing up for our services for his and his family’s I-485 applications.
