Case Summary:

Building successful EB1-A cases for our clients requires that we at Chen Immigration Law Associates not only prove that our client meets the regulatory criteria set by the USCIS but also showcase that our client has a level of expertise indicating that their research has sustained national or international acclaim and that their achievements have been recognized in the field of their expertise.

For this case, we highlighted the importance of this client’s research in hepatitis B and C infection which directly affects 600 million people worldwide. Moreover, we utilized the economic weight that these diseases impose on the world population as another tool in which we could bolster our client’s petition. Each year, both infections have caused huge amount of health care spending. In 1997 alone, the U.S. spent $5.46 billion on managing hepatitis C based on a conservative estimation. Using this information in combination with our client’s background in clinical research allowed us to illustrate that our client’s work has substantially benefitted the United States.

Another criterion we at Chen Immigration Law Associates must prove is that a client will substantially and prospectively benefit the United States. We compile and draft a series of Independent Advisory Opinion letters that reflect the contributions of our client’s work. These letters give case reviewers an unbiased opinion of the exceptionalness of the client’s work and research. In this case we drafted letters from professors and researchers who had not worked with our client, but rather were familiar with his work through their publications and international reputation. Moreover, in these letters we highlighted all positive areas of this client’s research whether that was discoveries, unique technical know-how, or a unique multidisciplinary background. In this case, we specifically tuned these letters to highlight the novelty and nuanced techniques that this client had exhibited throughout his work.

Also when drafting a petition we at Chen Immigration Law Associates highlight our client’s significant contributions to their field. This shows that our clients’ status is deemed as one of the top in their field, which is important to the success of the case’s approval. In this case we highlighted the client’s fifteen peer-reviewed scientific articles successfully published in prestigious journals including the Journal of Virology and Journal of Immunology. Regarding the evidence of the petitioner’s participation as a judge of the work of others, this client held the position of Editorial Board Member for an internationally recognized journal, and had served as a peer-reviewer for at least 6 distinctive globally circulated journals.

Using this proven strategy, while correctly articulating the importance surrounding this client’s valued work, we at Chen Immigration Law Associates were able to secure approval for this petition on March 15th, 2013.

With this in consideration, it is important to emphasize that the processes and expertise practiced by Chen Immigration Law Associates. Not only do we develop the best possible strategies for each case, but we execute these strategies with the utmost effectiveness!
