Success Stories: Immigration Officers Expeditiously Approve EB-1A Petition for Senior Scientist from China in the Field of Chemistry


Client’s Testimonial:

“Thank you very much again for all your help during my [I-140] preparation. Before I asked Wegreened for help, I was concerned and doubted about my qualifications for EB1A based on my moderate case background. You professionally drafted all the recommendation letters and petition letter, which required only minor revisions to a few words. Besides, you also helped me figuring out more highlights of my academic accomplishments and therefore made my case strong enough to pass PP at once. In addition, your prompt and detailed replies through the case system always gave me clear answers and explained me the best way to go. I definitely will recommend Wegreened to my friends in the future, based on my very happy experience with you.”

On March 8th, 2016, we received another EB-1A (Alien of Extraordinary Ability) approval for a Senior Scientist in the Field of Chemistry (Approval Notice).


General Field: Chemistry

Position at the Time of Case Filing: Senior Scientist

Country of Origin: China

Service Center: Nebraska Service Center (NSC)

State of Residence at the Time of Filing: New Jersey

Approval Notice Date: March 8th, 2016

Processing Time: 11 Days (Premium Processing Requested)

Case Summary:

A prominent senior scientist from China engaged the services of North America Immigration Law Group ( to help him file an I-140 petition under EB-1A (Alien of Extraordinary Ability). Although our client had strong credentials, he needed our help to develop a strong presentation that would convince the USCIS to approve his EB1A petition.

Premium Processing:

Our client initially contacted us to file an EB-1B petition on his behalf but opted for EB-1A instead. Thanks to Premium Processing (PP), he received an approval notice from Nebraska Service Center (NSC) just 11 days after we filed the petition on his behalf. PP is only available for certain visa categories (such as EB-1) and allows for speedy adjudication. Immigration officers have to take action on PP cases within 15 days as opposed to 4-9 months for regular cases. This makes PP a suitable option for petitioners who are disinclined to wait several months for a response from the USCIS. The only catch is that the USCIS charges approximately $1,225 for this service (on top of regular filing fees).

Client’s Credentials:

With 128 citations to his work and 11 published papers to his name, our client is considered one of the top researchers in his field of chemistry. His high standing in the field is further solidified by the nearly three dozen times he conducted peer reviews for various high impact scientific journals. We made sure to include as many details as we could on our client’s professional accomplishments as they served as solid evidence that his work not only benefits other researchers in his field, but the United States as a whole. A senior scientist at one of America’s top corporations had this to say about our client: “[Client’s] innovative research, considerable publication and citation record, and peer review experience certainly speak to his prominent standing in the field…” He was not alone in this encouraging show of support. Several other influential chemists contributed recommendation letters to fortify our client’s EB1A petition.

Research Endeavors:

Our client’s work is focused on synthetic organic chemistry, analytical chemistry, and green chemistry. We demonstrated that his efforts address some of the United States’ most pressing issues in accelerating drug discovery, streamlining chemical production, and using renewable resources in the synthesis of plastics. According to a well-known professor of chemistry who contributed a recommendation letter to strengthen our client’s petition, “[Client’s] research perspective is unique; he has applied his extensive academic training in organic chemistry, analytical chemistry, and green chemistry to [e]ffect great change in the synthesis and analysis of organic compounds.”

EB1A Petition Approval:

Our client’s solid credentials and our carefully prepared presentation lent a hand in persuading the USCIS to approve our EB1A petition. We are pleased that we can chalk this approval up as yet another success story for our firm. We would like to congratulate our client on this milestone, and we wish him the best with his I-485 application. Once our client surpasses this final hurdle, he will be rewarded with his green card.
