Why Trump’s plan to put restrictions on H-1B visa may not help US workers

The H-1B visa-holders, a majority of them Indian IT professionals, do not adversely affect Americans, according to new research, which also suggests that the presence of foreign workforce having such visas boost employment among other workers in an occupation.

The H-1B visa is a non-immigrant visa that allows US companies to employ foreign workers in speciality occupations that require theoretical or technical expertise. Companies depend on it to hire tens of thousands of employees each year from countries like India and China.
