EB1A (EB1-EA) approval in 5 days after upgrading to premium processing for Statistical Machine Learning Expert. (Approval Notice)

Case Summary:

On Dec. 3^rd, another one of Chen Immigration Law Associates’ EB1A (EB-1 EA) cases was successfully adjudicated in favor of our client. In this case, our client was involved in domain-specific knowledge mining at a prestigious University in Kansas. We framed the petitioner as an expert on Statistical Machine Learning with expertise in Bioinformatics, Natural Language Processing, and Artificial Intelligence.

In practice, we successfully argued our client’s case by clearly presenting his work on algorithms that allow computers to evolve behaviors in a way the USCIS recognized favorably. In addition, we drafted six letters of recommendation highlighting our client’s unique expertise in Statistical Machine Learning and strong academic background in mathematics, computer science and statistics to distinguish him from other applicants.

With a strong record of accomplishment, our client’s foreign-based research was argued to enhance the impact of his current work and prove sustained performance in his field. As such, the U.S.C.I.S. agreed that our client’s innovative studies provide sophisticated computational models for the sorting and classification of data, which is in US national interest. Ultimately, the case was approved in 5 days after our client upgraded his case to Premium Processing.
