H1B Visas is the official and primary work visas / work permit for foreign professionals. The US Government introduced the H1B visa to offer and enable highly skilled International Professionals from all over the World, the opportunity to live and work in the USA. H1B Visas are typically given to professionals possessing practical work experience or a relevant qualification degree in a specialty field. H1B visa holders are given opportunities only in circumstances where permanent citizens of the US do not meet the job requirements. While offering H1B visa holders with job opportunities, employers have to attest that such a step does not harm the conditions for US workers. An H1B is usually valid for up to six years and entitles the holder to bring their spouse and children to live in the country.
