Case Summary:

Chen Immigration Law Associates recently received an EB1A  for a postdoctoral fellow from China. This client seeks to enter the United States to continue working in the field of biomedical sciences. Our client’s work primarily focused on the function and regulation of cellular signaling, and their roles in human disease initiation and progression, information which offers much therapeutic potential. Not only does our client’s studies further the research of the mechanisms behind diseases such as cancer, but they also pinpoint new targets for drug interventions. It was our goal to prove that this client qualifies for classification as an alien of extraordinary ability given that he seeks to enter the United States to continue work in the area of extraordinary ability and that his entry into the United States will substantially and prospectively benefit the United States. Our client’s work has resulted in 7 peer-reviewed scientific articles. His publications have been cited at least 150 times by researchers from 27 countries around the world. His contributions to the field are also recognized by other experts, notably in a statement by an independent recommender who stated, “Since cancer is one of the leading causes of death among Americans, sophisticated methods of identifying and targeting new treatments of the disease are essential for improving national health…His studies will be critical to future improvements in the detection and treatment of cancers and other diseases.” We at Chen Immigration Law Associates collected recommendation letters from leading experts in the field that argue the necessity of continuation of our client’s work. This client’s case was approved in just 5 days after upgrading to premium processing.
