In a huge relief to tens of thousands of Indian professionals and top American IT firms, a US court has blocked two H-1B regulations proposed by the Trump administration to restrict the ability of American companies to hire foreign employees.

H-1B visas is a non-immigrant visa that allows American companies to employ foreign workers in speciality occupations that require theoretical or technical expertise. The US issues up to 85,000 H-1B visas each year. Usually, they're issued for three years and are renewable. Most of the nearly 600,000 H-1B visa holders are from India and China.
