The H-1B visa allows U.S. employers to temporarily employ foreign workers in specialty occupations that usually require a bachelor's degree or equivalent experience. It is granted for an initial period of three years, with potential extensions, and includes provisions for spouses and children to join the worker with an H-4 visa. There is a cap of 65,000 H-1B visas issued per fiscal year, with applications starting in April and a lottery system in place if applications exceed available visas.

2. WHAT IS USA H1B VISA?
 The H-1B is a non-immigrant visa in the United
States that allows US employers to temporarily
employ (sponsor) foreign workers in specialty
occupations. If a foreign worker in H-1B status quits
or is dismissed from the sponsoring employer, the
worker must either apply for or be granted a change
of status to another non-immigrant status, find
another employer or leave the US.

3. H1B VISA REQUIREMENTS
 To qualify for an H1B visa to work in the US, a foreign
worker must have a temporary offer of employment in a
specialty occupation from a US employer.
 A specialty occupation is an occupation that requires
theoretical and practical application of specialized
knowledge that usually requires the equivalent of at least a
bachelor's degree or equivalent work experience. Typical
specialty occupation fields include architecture,
engineering, mathematics, physical sciences, medicine,
health, education, business specialties, accounting, law,
theology and the arts. Fashion models of distinguished
merit and ability may also qualify for an H1B visa.

4. H1B VISA ENTITLEMENTS
 An H1B visa entitles the holder to live and work in the US
temporarily. An H1B visa is usually granted for an initial
period of 3 years and extensions may be granted. Foreign
workers with an H1B visa are permitted dual intent,
meaning the applicant can maintain H1B visa status while
applying for a Green Card to remain in the US permanently.
 Spouses and unmarried children under 21 years of age
may apply for the applicable derivative visa (H4 visa) to join
their spouse or parent in the US. Accompanying spouses
and children are entitled to study in the United States but
are not entitled to undertake any employment without
obtaining an appropriate work visa.

5. KEY HIGHLIGHTS
 The US immigration legislation caps the number of
H1B visas issued to 65,000 per fiscal year (from
October 1 to September 30). The United States
Citizenship and Immigration Services (USCIS)
starts accepting applications on the first business
day of April for visas that count against the fiscal
year starting in October. If there are more
applications than available visas, there is a lottery
system that decides whose application makes it
through for that year
