Case Summary:

  • Our Client:

A China-born postdoctoral fellow working in the field of analytical chemistry 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:
  1. At the time of filing, our client had garnered a massive 348 citations to his published work which included 20 peer-reviewed scientific articles published in high impact journals. Additionally, he had to his credit a patent. These remarkable accomplishments were duly included in the EB1A dossier.
  2. An impressive peer-review record set our client apart from other researchers. At the time of filing, he had already completed 24 reviews for at least 3 top-tier journals. This achievement was an important milestone in his research career which indicated the influence and respect our client had gained in his chosen field.
  3. It was also imperative that we present key points of our client’s research in the EB1A dossier. Our client’s specialized research focused on the development and implementation of analytical methods that enable chemists and biological researchers alike to assess and, if necessary, adjust the quality of herbal medicinal compounds. His work directly impacts the research community in the United States by helping them understand herbal medicine better, such as the inherent toxicity of plant compounds or their inability to resolve certain health defects. Our client’s strong background in analytical chemistry empowered him to develop applications such as quality assurance, therapeutic production, and natural drug discovery. If allowed to continue his research in the United States unhindered, it could potentially lead to the discovery of reliable herbal compounds, which in turn leads to the development and clinical implementation of useful natural pharmaceuticals and therapeutics. It was our job to convince the USCIS of the need to retain our client in the US for the nations’ benefit.
  • Recommendation letters:

As per our advice, our client successfully managed to gather 4 recommendation letters from experts. A statement made by a distinguished professor read:

“As [Client] has proven to be a strong authority in pharmaceutical development, he is virtually guaranteed to continue making progress in this important field.”

Undoubtedly, these 4 letters helped strengthen our client’s case to a great extent.

  • Filing the EB1A petition:

After carefully assembling the required documents, our team filed the EB1A petition with Premium Processing (PP) on behalf of our client. PP is a paid option offered by the USCIS whereby speedy adjudication of the petitions happen within 15 days (which otherwise takes 4-9 months). We congratulate our client on his EB1A success and wish him the very best as he progresses the field of analytical chemistry.
