Success Stories: Premium Processing Leads to EB-1A Petition Approval in 5 Days for Postdoctoral Fellow in Missouri in the Field of Biomedical Sciences


Client’s Testimonial:

“Thanks to you. I think our hard work has finally paid off (at least partially, for now). I am also glad to let you know that I have received the approval notice in the mail today. I have already referred your firm to a couple of colleagues, because I liked your professionalism, and always being helpful and responsive.”

On March 9th, 2016, we received another EB-1A (Alien of Extraordinary Ability) approval for a Postdoctoral Fellow in the Field of Biomedical Sciences (Approval Notice).


General Field: Biomedical Sciences

Position at the Time of Case Filing: Postdoctoral Fellow

Country of Origin: China

Service Center: Nebraska Service Center (NSC)

State of Residence at the Time of Filing: Missouri

Approval Notice Date: March 9th, 2016

Processing Time: 5 Days (Premium Processing Requested)

Case Summary:

Largely due to Premium Processing (PP), our client’s EB-1A (Alien of Extraordinary Ability) petition was approved in merely five days. We have no doubt that our client’s strong credentials and our meticulously prepared presentation persuaded the immigration officers at Texas Service Center to grant their approval.

More about Premium Processing:

PP is an option available only to certain visa categories, EB-1 being one of them. As our client’s petition was filed under EB-1A, he had the luxury of paying an additional $1,225 to have his case adjudicated under PP. Although it costs more, it saves petitioners plenty of time—the USCIS must take action on PP cases within 15 days as opposed to 4-9 months for regular cases.

Our EB-1A Petition Dossier:

Our years of experience putting together EB-1A petitions has taught us that attention to detail is extremely important. Thus, we carefully compiled all the relevant information into a well-worded petition dossier. We also incorporated recommendation letter volunteered by experts working in our client’s field of biomedical sciences. Here are bits and pieces of their letters and the main points of our EB-1A presentation:

  1. Professional Performance:
  • “His thirteen publications set him apart from his peers as a highly prolific researcher. In addition, [Client’s] work has been cited on over 240 occasions at the time of this writing, demonstrating how others in the field have come to rely on [Client’s] expertise.”

When we filed the case, our client’s 13 published scientific papers had accumulated 247 citations. This signifies the value of his work to other researchers in the field. We also documented the 17 times he contributed his insights to his peers by carrying out peer review service for high impact scientific journals.

  1. Research Results:
  • “This consistent record of excellence, as manifested both by his groundbreaking research on the effects of obesity and colitis on bone marrow as well as his overall record of publications and citations, has cemented [Client’s] place as one of the most innovative minds working in his field today.”

Our client’s extensive experience in the field of biomedical sciences has thus far been focused on microbiology, vaccinology, and veterinary medicine. His efforts to understand the genetic origins of disease and how to develop vaccines against them are of great value to the United States.

  1. Supporting Information:
  • “This success in his research is backed by thorough training and extensive credentials. [Client] obtained his Ph.D. in Biomedical Sciences from […] and prior to that he earned a B.Sc. in Biology from […].”

By detailing our client’s academic background, we demonstrated to the USCIS that he is armed with the essential knowledge, skills, and dedication to continuously carry out high quality research in his field.

Final Step:

We congratulate our client for receiving an EB-1A approval notice from the USCIS. As our client chose to file his I-485 application (final step towards a green card) and EB1A petition concurrently, he is currently awaiting the second approval notice from the USCIS. Once they approve his I-485, he will become an official U.S. permanent resident.
