On June 11th, 2019, we received another O1-A (Individuals with Extraordinary Ability or Achievement) approval for a Rheumatology Fellow in the Field of Clinical Medicine (Approval Notice).

General Field: Clinical Medicine

Position at the Time of Case Filing: Rheumatology Fellow

Country of Origin: Colombia

State of Residence at the Time of Filing: New York

Approval Notice Date: June 11th, 2019

Processing Time: 8 days (Premium Processing Requested)

Case Summary:

A Rheumatology Fellow from Colombia approached North America Immigration Law Group ( to file an O1-A (Individuals with Extraordinary Ability or Achievement) petition on her behalf. As O1-A is an employer-sponsored visa category, our client could not self-petition and needed her employer’s full support before hiring us. Once we received confirmation from our client and her employer, our team went on to build a strong case for her. Since our client opted for Premium Processing (PP) with her O1-A petion, her case was approved in only 8 days.

One of the first steps we took was to thoroughly analyze our client’s credentials and qualifications. First, we detailed several of her research projects that focused on rheumatic disease pathogenesis and rheumatic disease outcome predictors, which help better understanding and predicting the outcomes of rheumatic diseases in a clinical setting. In the petition letter, we noted 8 peer-reviewed scientific articles that showcased her significant contributions to the field. The fact that these publications have been cited a total of 90 times in other peer-reviewed journal articles indicated that other researchers in the field have been substantially impacted by her work and findings. Besides, she had also conducted at least 2 peer reviews for an esteemed journal in rheumatology. The evidence we collected all proved that our client and her valuable research has an enormous impact on public health.

In support of our client’s O1-A petition, several well-known medical experts volunteered recommendation letters. These letters provided subjective evidence of the importance of our client’s work to the US. According to one of the recommenders: “[Client] has been instrumental in research efforts aimed at confronting the growing threat of drug-resistant antibiotic diseases. Her studies have been exceptional in revealing some of the mechanisms and pathogenesis of infectious diseases that plague the global population. The field would be at a severe loss without her continued commitment to cutting-edge investigations”.

After months of diligent work, we successfully demonstrated that our client had satisfied the O1-A criteria. We congratulate her for securing O1-A petition approval and we wish her the best as she continues to advance the important field of clinical medicine here in the United States.
