Success Stories: EB-1A Petition Approved in One Week for Scientist in Wisconsin in the Field of Chemistry (PP Without RFE)


Client’s Testimonial:

“Thank you.”

On April 18th, 2016, we received another EB-1A (Alien of Extraordinary Ability) approval for a Scientist in the Field of Chemistry (Approval Notice).


General Field: Chemistry

Position at the Time of Case Filing: Scientist

Country of Origin: China

Service Center: Nebraska Service Center (NSC)

State of Residence at the Time of Filing: Wisconsin

Approval Notice Date: April 18th, 2016

Processing Time: 7 Days (Premium Processing Requested)

Case Summary:

Just one week after we filed an EB-1A (Alien of Extraordinary Ability) petition on behalf of a gifted scientist from China, the USCIS took action on his case by granting their approval. Thanks to Premium Processing (PP), our client did not have to wait between 4-9 months for the USCIS to adjudicate his case.

What is PP?

PP is a paid option offered by the USCIS. All petitioners have to do is submit an I-907 form and pay the USCIS an additional $1,225 to enjoy rapid processing (within 15 days instead of 4-9 months). Although this is a great option for petitioners who are unable or unwilling to wait several months for the USCIS to take action on their case, not everyone qualifies for PP. According to the USCIS, only certain visa categories can take advantage of PP, and thankfully for our client, EB-1A is one of the approved categories.

Putting Together a Strong EB-1A Petition:

EB-1A is upheld by a very high standard of law and it is not easy getting a petition approval. Thus, we had to pay very close attention to detail in preparing our client’s EB-1A petition dossier. Some of the information we focused on included the 247 citations to his work, the 18 times he conducted peer reviews for scientific journals, and his 5 publications. In addition to that, we included recommendation letters contributed by other expert chemists. They willingly lent their support for the approval of our client’s EB-1A petition and verified the importance of his research on the development of chemosensors for the detection of metal ions, pH change, and chemical compounds (such as hydrazine) in solution. Here is what one of our client’s recommenders had to say about his work: “[Chemosensors] have a broad range of applications, ranging from environmental to industrial to electronic…[Client’s] research is [thus] crucial to the United States as the country continues to progress in chemosensor technology.” Another expert stated that “Considering the value presented by his research to multiple industries in the United States, I must argue that the cessation of [Client’s] research would certainly be an overall detriment…”

North America Immigration Law Group ( would like to congratulate our client for overcoming this significant hurdle in the green card process, and we wish him well as he files an I-485 application (last step in the green card process).
