NEW DELHI: Facebook , one of the best paymasters at engineering campuses, is likely to give the Indian Institutes of Technology (IITs) a miss this year, both for internship and final placement, according to sources from IIT placement cells.This is not because the company has lost its appetite for Indian engineering talent, but due to the limited H-1B visas issued to companies by the US. At least five IITs confirmed that the online social networking service, headquartered in Menlo Park, California, was not visiting them this year.Facebook had made about a dozen offers at three of these institutes last year with salaries going upwards of a crore and even touching Rs 2 crore for positions of software engineers in California.Facebook declined to comment. But sources close to the company said it had visa problems last year too. It was forced to position its IIT hires at the UK for almost a year before getting visas in place for the US. "Facebook did not come this year for undergraduate interns at our IIT," confirmed Atal Ashutosh Agarwal, Vice President, Technology Students' Gymkhana at IIT Kharagpur. It is the same story at other IITs. "This year, Facebook has still not approached us and they are unlikely to turn up for the pre-placement offers too," said a student placement cell head of a leading IIT. He added that the social networking company usually picked up at least a couple of UGs from each of the leading IITs last year."Visa is an issue for US based technology companies that hire from India," said former placement manager at IIT Bombay, Mohak Mehta. The current quota for H1B visas is 65,000 which is exhausted in a matter of days of the annual allocation becoming available at the beginning of April each year. US demand for talent in science, technology, engineering and mathematics (STEM) is estimated to go up to a million by the year 2020."Considering that a million of STEM workers would be needed by the US in some years, they are likely to fall short by almost 50 per cent. India has a good supply of talent in this space, which also includes the young IITians," said Shivendra Singh, VP, NASSCOM.The limited number of visas is an issue. India needs to lobby for easier norms. However, career-wise it would make better sense to enroll for a master’s or higher degree in the US. For such graduates, there are exemptions available over and above H-1B caps. Also, those working at -- not necessarily for -- universities, non-profit research facilities associated with teaching establishments, and government research centres are exempt from the quota ceiling. Due to exemptions and roll-overs, the actual number of H-1B visas issued each year is far higher than the limit of 65,000, often twice as much. But the cap needs to be reviewed.
