This work focuses on the data science challenge problem of predicting the decision for past immigration visa applications using supervised machine learning for classification.

The H-1B visa allows employers in the United States to temporarily employ foreign nationals in various specialty occupations that require a bachelor’s degree or higher in the specific specialty, or its equivalents. These specialty occupations may often include, but are not limited to: medicine, health, journalism, and areas of science, technology, engineering and mathematics (STEM). Every year the United States Citizenship and Immigration Service (USCIS) grants a current maximum of 85,000 visas, even though the number of applicants surpasses this amount by a huge difference and this selection process is claimed to be a lottery system.
