The H-1B Visa is a temporary work visa designed for foreign nationals who will be employed in specialty occupations. These occupations require the theoretical and practical application of a body of highly specialized knowledge, such as fields in science, engineering, and information technology, and require at least a bachelor's degree or its equivalent.
The H-1B Visa allows for an initial period of stay of up to three years, which can be extended up to a maximum of six years. However, under certain conditions, H-1B holders who are in the process of obtaining lawful permanent resident status (Green Card) can extend their stay beyond six years. The spouse and unmarried children under 21 years of age of the H-1B visa holder may seek admission under the H-4 nonimmigrant classification.
One key point to note about the H-1B Visa is that it is subject to an annual cap, with a certain number of visas set aside for individuals with a master's degree or higher from a U.S. university. The employer must submit a petition for the H-1B Visa, which typically includes details about the offered position, the qualifications of the employee, and the wage being offered.
