He was speaking at the Advancing Asia Conference co-hosted by India and IMF.Subramanian said services-led export model can push India to achieve 8-10 per cent sustained growth but talk on H1B scrapping was worrying.Republican party frontrunner Trump during his campaign had said, the H1B Visa programme that allows US employers to hire foreign workers in specialty occupations, should be ended.
