Success Stories: EB-1A Petition Approved Nearly 10 Months after Filing for Chinese Assistant Professor with 76 Citations in the Field of Biostatistics


Client’s Testimonial:

“I would like to express my sincerely appreciation to WEGREEN team for your help in my I-140 application. Your team is very professional, having a lot of experience and always answer my question on time. My EB-1B case prepared by another law firm was denied in 2015. After I discussed my case with your team, you think my case is feasible for EB1A, which is known to be harder than EB1B in general.  You gave me the confidence to submit both EB1A and NIW, which is great suggestion and totally worth the waiting. There is almost no simply “copy and paste”, and WEGREEN must spend a lot of time to read through my materials and use their own word to show my contribution. It’s a very pleasure experience to work with WEGREEN and I would recommend you without hesitate.”

On March 10th, 2017, we received another EB-1A (Alien of Extraordinary Ability) approval for an Assistant Professor in the Field of Biostatistics (Approval Notice).

Case Summary:

A well-known biostatistician from China approached North America Immigration Law Group (NAILG) to help her get one step closer to green card success. To increase her chances of obtaining petition approval, she retained our firm to file two I-140 petitions: one under EB-2 NIW (National Interest Waiver) and the other under EB-1A (Alien of Extraordinary Ability). At the time of writing, our client had recently received the good news that her EB-1A petition had been approved nearly 10 months after filing while her NIW petition was still being processed.

As part of our comprehensive services, we proved to the USCIS that the field of biostatistics has seen much progress since our client chose to dedicate her career to it. Not just that, we demonstrated that her research efforts are significantly benefiting the United States, most notably its economy. According to a prominent professor who contributed a recommendation letter in support of our client’s EB-1A petition: “Scientists of [Client’s] capabilities have become increasingly valuable to countries such as the United States, whose healthcare and pharmaceutical industries are significant portions of the economy.” According to another expert working in the field of biostatistics: “[Client] is among that group in our field, and her guidance has repeatedly allowed her colleagues in the United States and around the world to conduct their biomedical research more effectively.”

Besides strong letters of recommendation, our client’s EB-1A dossier contained information pertaining to her citation count, publication record, and peer review experience. At the time of filing, these numbers stood at 76 citations, 10 published articles, and a dozen instances of peer review service. We used these numbers to persuade the USCIS that our client is one of only a handful of researchers whose opinions are highly respected by others working in the field of biostatistics.

As we were able to demonstrate that our client’s specialized research efforts focused on statistical inference, methodology development, data analysis, and modeling are beneficial to the nation, the USCIS approved her EB-1A petition. We are glad that our client has passed this first, significant hurdle in the green card process, and we wish her all the best as she continues to progress the field of biostatistics.
