The H-1B visa is designed to be used for staff in "speciality occupations", that is those occupations which require a high degree of specialized knowledge. Since the beginning of the FY 2010 is October 1, 2009, employers can apply as soon as Apfor the FY 2010 cap, but the beneficiary cannot start work until October 1st. US employers may begin applying for the H-1B visa six months before the actual start date of the visa. H-1B visas are subject to annual numerical limits. The employer must petition for entry of the employee. Individuals can not apply for an H-1B visa to allow them to work in the US. As applying for a non-immigration visa is generally quicker than applying for a US Green Card, staff required on long-term assignment in the US are often initially brought in using a non-immigrant visa such as the H-1B visa.

The US H-1B visa is a non-immigrant visa, which allows a US company to employ a foreign individual for up to six years.
