Case Summary:

On February 4, 2013, we at Chen Immigration Law Associates received another EB1-A (Alien of Extraordinary Ability) petition approval. EB1-A cases require the following criteria to be met: extraordinary ability, continued work in the field of endeavor with substantial prospective benefit and international acclaim of recognized achievements. To win an extraordinary ability case requires extensive documentation and excellent petition skills of which we at Chen Immigration Law Associates have demonstrated by our impressive approval rates of EB1-A cases.

In this particular EB1-A, we argued that this petitioner met four of the criteria set forth. In addition, we argued that this client had indeed risen to the top of his field of endeavor and had sustained national and international acclaim on his achievements and was recognized in the field as a leading expert.

In order to demonstrate that this client’s work was extraordinary, we at Chen Immigration Law Associates drafted six recommendation letters on behalf of experts in the field who reviewed, edited and signed them. These prominent researchers provided expert testimony to the significant impact of this clients work in biomedical sciences and nanotechnology. To evidence both an unbiased opinion and international influence, two of these recommendation letters were from independent recommenders as well as other leading experts from the United Kingdom and India.

In addition, we at Chen Immigration Law Associates demonstrated that this client met the published material criterion and was indeed extraordinary in his field of endeavor. We presented as evidence his three sole authored books, 13 peer-reviewed scientific articles appearing in prestigious international journals, and his two book chapters. Furthermore, we argued that this client’s work had been cited by researchers from 250 different universities, companies and government laboratories across 25 countries.

Additionally, in order to prove to this client was indeed a leader in his field, we cited the five internationally prominent journals that requested his expertise as a peer reviewer. Furthermore, we documented this client’s positions held as editor which further proved his significant influence and leadership in his field of endeavor.

We at Chen Immigration Law Associates are skilled in assessing each client’s individual needs and presenting them to ensure that the strengths of the client are clear and concise. Finally, drawing upon this skill and experience, we at Chen Immigration Law Associates cited relevant AAO (Administrative Appeals Office) decisions to further document the evidence necessary to gain approval for this client’s EB1A petition.

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 February 4, 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!
