- Project : Analyzing H1B Acceptance trends and factors relating to it.
H1B visa is a nonimmigrant visa issued to graduate level applicants allowing them to work in the United States. The employer sponsors the H1B visa for workers with theoretical or technical expertise in specialized fields such as in IT, finance, accounting etc. An interesting fact about immigrant workers is that about 52 percent of new Silicon valley companies were founded by such workers during 1995 and 2005.
Some famous CEOs like Indira Nooyi (Pepsico), Elon Musk (Tesla), Sundar Pichai (Google),Satya Nadella (Microsoft) once arrived to the US on a H1B visa.
Motivation: Our team consists of five international graduate students, in the future we will be applying for H1B visa. The visa application process seems very long, complicated and uncertain. So we decided to understand this process and use Machine learning algorithms to predict the acceptance rate and trends of H1B visa petitions.
The goal of the project is to analyse the various trends in the H1b Visa dataset.We have two ML Models to predict acceptance or rejection of visa application and to predict the wage_rate of an applicant.
With the below visualizations in the notebook we provide insights into the H1B visa.
-
Salary distribution for Data Science Domain.
-
Number of jobs in Data Science Domain.
-
Top 10 employers who sponsor H1B Visa.
-
Job Distribution in the US for each State.
-
Education level comparison for each Degree.
The data used in the project has been collected from the Office of Foreign Labor Certification (OFLC).The Data provides insight into each petition with information such as the Job title, Wage, Employer, Worksite location etc. To download the data follow the steps below:
