The H-1B visa, most sought-after among Indian IT professionals, is a non-immigrant visa that allows US companies to employ foreign workers in speciality occupations.

US President Donald Trump, in his June proclamation, banned the entry into the US of workers in several key non-immigrant visa categories.

Under these reforms, the H-1B programme will prioritise those workers who are offered the highest wage, ensuring that the highest-skilled applicants are admitted, the White House said.

The H-1B is a non-immigrant visa that allows US companies to employ foreign workers from countries like India and China in speciality occupations that require theoretical or technical expertise.

The H-1B program allows companies in the United States to temporarily employ foreign workers in occupations that require the application of highly specialised knowledge

The US is considering restrictions on H-1B visa that allow foreign professionals to work in that country.
