A recent study conducted has shown that there is a high demand for skilled H-1B workers in metropolitan areas. An analysis of the geography of H-1B visa requests — particularly in the metropolitan areas with the highest demand between 2001 and 2011 — reveals that demand for H-1B workers has fluctuated with economic and political cycles over the last decade and reflects a wide range of employers’ needs for high-skilled temporary workers. Employer requests have exceeded the number of visas issued every year except from 2001 to 2003 when the annual cap was temporarily raised from 65,000 to 195,000. Employers requesting the most H-1B visas are large companies subject to the cap specializing in information technology, consulting, and electronics manufacturing. Science, technology, engineering, and mathematics (STEM) occupations account for almost two-thirds of requests for H-1B workers; healthcare, finance, business, and life sciences occupations are also in high demand. Over the last decade the federal government has distributed about $1 billion from H-1B visa fees to fund programs to address skills shortages in the U.S. workforce.
One hundred and six metropolitan areas had at least 250 requests for H-1B workers in the 2010–2011 period, accounting for 91 percent of all requests but only 67 percent of the national workforce. Considerable variation exists among these metro areas in the number of workers requested and the ratio of requests to the size of the total metro workforce. On average, there were 3.3 requests for H-1Bs per 1,000 workers in these 106 metro areas, compared to 2.4 for the nation as a whole.
