Success Stories: EB-1A Petition Approved for Postdoctoral Scholar from China in the Field of Molecular and Cellular Biology


Client’s Testimonial:

“Thank you so much for your work.”

On February 5th, 2016, we received another EB-1A (Alien of Extraordinary Ability) approval for a Postdoctoral Scholar in the Field of Molecular and Cellular Biology (Approval Notice).

General Field: Molecular and Cellular Biology

Position at the Time of Case Filing: Postdoctoral Scholar

Country of Origin: China

Service Center: Nebraska Service Center (NSC)

State of Residence at the Time of Filing: California

Approval Notice Date: February 5th, 2016

Processing Time: 11 days (Premium Processing requested)

Case Summary:


A recent client of ours was described as “…being at the vanguard of his field, as he has consistently proven that he is able to perform at a level that is well beyond the ability of his peers.” This statement was offered by an expert biologist, who contributed a recommendation letter in support of our client’s EB-1A (Alien of Extraordinary Ability) petition. Several other experts provided similar letters, which North America Immigration Law Group included in our well-worded I-140 presentation to the USCIS.

In our carefully prepared petition packet, we included various aspects of our client’s professional portfolio: his doctoral degree, the 1233 citations of his work, his 5 publications, and the 14 times he assessed the work of other scientists in his field of molecular and cellular biology. We convinced the USCIS that our client’s research on applying molecular biology to the understanding of epigenetic regulation mechanisms progresses our understanding of DNA methylation/demethylation. We proved that his findings greatly benefit the country’s scientific community as well as various American industries.

Because our client elected to file under Premium Processing (which greatly reduces the wait time for a decision), he received an approval notice 11 days after we filed his case. We would like to congratulate our client on completing the first leg of the green card journey and we wish him well with his continued research in the field of molecular and cellular biology.
