Success Stories: Materials Science Researcher Based Outside the US Obtained EB-1A Approval and Is Now Ready for Immigrant Visa Processing

Client’s Testimonial:

“Thank you for your message.”

On March 9th, 2017, we received another EB-1A (Alien of Extraordinary Ability) approval for a Researcher in the Field of Materials Science (Approval Notice).

General Field: Materials Science

Position at the Time of Case Filing: Researcher

Country of Origin: South Korea

Service Center: Texas Service Center (TSC)

State of Residence at the Time of Filing: Outside the US

Approval Notice Date: March 9th, 2017

Processing Time: 8 Days (Premium Processing Requested)

Case Summary:

A South Korean researcher based outside the US hired North America Immigration Law Group ( to file an EB-1A (Alien of Extraordinary Ability) petition on his behalf. With a doctoral degree and various accolades in the bag, our client seemed like a suitable candidate for this strict I-140 category.

Building a strong EB1A case:

We were tasked with proving to the USCIS that our client’s continued work (on the synthesis of nanomaterials for use in lithium ion batteries, lithium air batteries, water splitting applications, quantum-dot solar cells, biosensors, and various electronic devices) greatly benefits the United States. Furthermore, we had to prove that he has risen to the top of the field of materials science and is a researcher of extraordinary ability.

After months of hard work, we managed to gather a wealth of information related to our client’s achievements. For instance, we noted the 760 citations gathered from his 20 publications, and the 4 times he assessed the work of his peers for scientific journals.

We further strengthened our client’s EB1A case by presenting recommendation letters signed by other influential members of the materials science research community. According to one of them, a well-known assistant professor, our client is “certainly one of the most preeminent and well-respected researchers of batteries and I have no doubt that the field will continue to benefit from his fine and pragmatic work.” 

Obtaining a green card:

There are two steps in the green card process: (1) filing an I-140 petition and (2) filing an I-485 application or undergoing immigrant visa processing (IVP). In this case, our client does not live in the US and therefore must go through the latter process which involves attending an interview at the American embassy/consulate in his country of residence. Assuming everything goes well, he will be issued an immigrant visa which he will then use to enter the US as a permanent resident. We thank him for retaining our IVP services and look forward to helping him obtain his green card.
