On March 23rd, 2016, we received another EB-1A (Alien of Extraordinary Ability) approval for a Post-doctorate Research Associate in the Field of Analytical Chemistry (Approval Notice).

General Field: Analytical Chemistry

Position at the Time of Case Filing: Post-doctorate Research Associate

Country of Origin: China

Service Center: Nebraska Service Center (NSC)

State of Residence at the Time of Filing: Washington

Approval Notice Date: March 23rd, 2016

Processing Time: 7 Days (Premium Processing Requested)

Case Summary:

One week after we filed an EB-1A (Alien of Extraordinary Ability) petition for a post-doctorate research associate from China, Nebraska Service Center sent us an approval notice. The accelerated timeframe was due to Premium Processing (PP), a paid option offered by the USCIS to quicken adjudication. Petitions filed under PP must be reviewed within 15 days as opposed to the 4-9 months needed for regularly filed cases.

Client’s Background:

Our client has extensive experience working in the field of analytical chemistry and has outperformed many of his peers. His development of new analytical and quantitative methods for the study of proteomics and their use in investigating human disease improves the United States’ understanding of the mechanisms driving biological systems and human disease on a minute scale, and how to improve tools like mass spectrometry for this purpose. His investigations are indubitably important to the U.S. as well as to local and international researchers in the field.

At the time of filing, our client’s 25 publications had gathered nearly 700 citations, and he had conducted 39 peer reviews for over 20 journals. His impressive credentials were supported by recommendation letters offered by other leading analytical chemists, all of whom confirmed that our client’s research findings are essential to the progress of the field. One of these experts described our client as “… a researcher at the top of his field, working diligently to reinforce the efficacy of mass spectrometry for the sake of proteomics research. [Client] is having a notable influence on his peers, as shown in his outstanding record of citation, and it would be a disservice to the field if his research were to be halted.”

We congratulate our client for surpassing this significant hurdle in the green card journey. He is now free to file an I-485 application, the final step towards a green card. We wish him well with this and look forward to congratulating him once again.
