It’s no secret that there’s a shortage of data scientists in America’s workforce. Many companies look to hire overseas to help ease the domestic talent shortfall (in fact, one in three data scientists are born outside the U.S.) so understanding the ins and outs of visas is rapidly becoming a business necessity. Not all visas are created equal. Some are drastically more expensive, can have lengthy approval processes, and low approval rates. In a tight labor market, it’s imperative that a hiring manager understand the immigration issues that affect who they can hire and how.
