Challenging the declaration of the number of American lawmakers that H-1B visas captured by IT professionals of India eat into their employment market, a recent study by a famous US think-tank has said that converse to such opinion; techies in India create jobs in the country. A report by the NFAP (National Foundation for American Policy) said converse to the popular opinion; Indian companies do not use the majority of the yearly H-1B allotment. Between monetary 2006 and 2011, the India-based top 25 companies utilised between 6-15% of the new H-1B visa agreed for early employment, and 19.9 percent in monetary 2012. In monetary 2012, the 26,865 new H-1B visas accepted for the India-based top 25 companies equalled only a 0.017% of the US labour force. Many of these industries perform services under a deal to assist US industries in focusing on core business purposes, it said. "Research indicates measures to restrict the use of H-1B visas are not based on sound evidence and would represent a serious policy mistake that would shift more work and resources outside the United States," said the report's author Stuart Anderson, NFAP's executive director. Instead of harming the US economy or the US workers, the holders of H1-B visa contributed "between 10 and 25 percent of the aggregate productivity growth that took place in the United States from 1990 to 2010," according to economists Giovanni Peri, Kevin Shih and Chad Sparber. Sparber and Peri, Shih also found, "An increase in foreign STEM workers of 1 percent of total employment increased the wage of native college-educated workers (both STEM and non-STEM) over the period 1990-2000 by 4 to 6 percent." STEM means Science, Technology, Engineering and Math. Economist Madeline Zavodny concluded that between the period 2001 and 2010, each added 100 accepted H-1B workers were connected with a bonus 183 jobs among US natives. A projected immigration reform bill established in the Senate recommends overhauling the H-1B visa program to stop its usage in outsourcing Americans jobs for nations like India.
