A Republican caucus has asked the Democrat leadership in the US House of Representatives to approve a proposed bill to nearly double the present “artificial” cap on H1-B visas, much sought-after by skilled professionals including Indians. The Republican Study Committee of the House of Representatives, in a letter to Speaker Nancy Pelosi and House Majority Leader Steny Hoyer, appealed to them to take up the legislation and pass it in the next few months. The panel called for an increase in the number of H1B visas from the current 65,000 to 115,000 and for 20 per cent built-in annual increase.
