Case Summary:

Our Client:

A China-born endocrinologist, with a doctoral degree in biophysics, approached our firm –– North America Immigration Law Group (NAILG) –– to help him file an EB-1A (Alien of Extraordinary Ability) petition. Before finalizing the attorney-client agreement, we assessed his credentials to ascertain his suitability for this visa category.

Client Credentials:

At the time of filing, our client had garnered 191 citations to his 15 publications (13 peer-reviewed journal articles, 2 abstracts). These noteworthy accomplishments were aptly and meticulously presented in the EB1A dossier.
Furthermore, our client had also been invited by impactful journals in the field of endocrinology to conduct peer-reviews: at the time of filing, he had already completed a remarkable 70 reviews. This achievement categorically established the high standing of our client in his chosen field.
It was imperative to include key points of our client's research in the petition. Our client's specialized work focuses on the molecular mechanisms affecting fetal health and preterm labor. More specifically, our client's contributions help the American scientific community understand the mechanisms underlying fetal overexposure to glucocorticoid, as well as glucocorticoid-induced premature labor. Our client's untiring efforts were instrumental in developing preventative strategies pertaining to premature labor and pregnancy complications. Needless to say, his continued presence in the United States will help address issues of fetal mortality.

Recommendation letters:

“Because of [Client's] valuable service to the field, along with the importance of his research to developmental biology and pediatric medicine, [Client] is certainly an irreplaceable member of the scientific community and one of the leading voices in his field.”

Such statements of appreciation contained in 6 recommendation letters proffered by experts in the field of endocrinology went a long way in establishing our client as a suitable candidate for EB1A approval.

Filing the EB1A petition:

After carefully assembling the required documents, our team filed the EB1A petition on behalf of our client. Roughly 5 months later, he requested that we upgrade his case to Premium Processing (PP). This was a decision that facilitated a quick response from the USCIS: the approval notification was received 8 days after the upgrade (the total adjudication time was 5 months and 13 days). We congratulate our client on his EB1A success and wish him the very best as he continues to progress the field of endocrinology.
