TheyALWAYS responds my questions with a professional answer within 2-4 business hours, the letters they drafted for me are so great and far beyond the quality I could expect.

Case Summary:

The average processing time for I-140 cases is four to six months. But on many occasions, we have had cases approved far faster than the average processing time.

At Chen Immigration Law Associates, we recently received an EB1B approval for an operations research scientist in the field of industrial and systems engineering. The beneficiary’s outstanding ability, highly skilled background, and impressive record of achievement provided a strong case for his EB1B petition. His work mainly focused on creating mathematical formulations, theorems, and optimization frameworks in order to answer fundamental questions having to do with matters such as capacitated production planning, or lot sizing. His research work has resulted in at least 17 peer-reviewed scholarly articles published in leading journals and conference proceedings in the field and 3 conference presentations. Furthermore, the beneficiary had a total of 68 citations by researchers around the world for his publications before filing the petition. The petitioner in this case is a publicly traded business that is dedicated to providing lifelong learning experiences for primarily adult students in order to improve their employment opportunities. Our beneficiary’s outstanding expertise is summarized in a quote by an independent recommender, “Nowhere are his talents in better evidence than in the interest that businesses have shown in his work over the past several years. His research at [company] and now at the [petitioner] has been both singular and influential, as should be clear from his recent and successfully granted patent and in his development of predictive models for the [petitioner]. He will undoubtedly continue to produce similarly beneficial work in the future.”  It was our goal to prove that this beneficiary qualifies for classification as an  outstanding professor or researcher given the international recognition for his outstanding achievements.
