The U.S. has strict laws surrounding who can enter, live, and work in the country. Many different types of visas exist to permit individuals to enter the U.S. for varying periods of time.
An H1-B visa exists to grant temporary residence and employment to foreign professionals in specific fields. The H1-B visa was created to help U.S. employers hire needed professionals, particularly when qualified individuals cannot be found in the domestic workforce.
An H1-B visa can be obtained by non-immigrant aliens who can prove they meet the professional requirements. An applicant must have an employment offer from an employer willing to sponsor the visa.
