According to Department of labour, a specialty occupation requires the theoretical and practical application of a body of specialised knowledge and a bachelor's degree or the equivalent in the specific specialty (e.g. sciences, medicine, health care, education, biotechnology, and business specialties, etc.).

Congress has limited the annual number of qualifying foreign workers who may be issued a visa or otherwise be provided the H-1B status to 65,000 with an additional 20,000 under the H-1B advanced degree exemption.

Before applying for the H-1B visas the employer submits a labour condition application to the Department of labour. Companies can proceed with the H-1B petitions, only after they receive such a certification by the Department of labour.
