A Work Visa is a type of temporary visa that allows an individual to legally work and earn income in a foreign country. It is typically granted for a longer duration than a tourist or business visa and allows the visa holder to engage in employment or business activities in the foreign country.

The specific requirements for a work visa can vary depending on the country and the purpose of the visit. In most cases, a job offer from a company in a foreign country is required to apply for a work visa, and the employer may need to sponsor the applicant's visa application. The applicant may also need to provide evidence of their qualifications, work experience, and financial stability, as well as undergo medical examinations and provide a police clearance certificate.

In some countries, such as the United States, the work visa process is divided into different categories, depending on the type of work and the qualifications of the applicant. For example, the H-1B visa is a popular work visa in the US for skilled workers in specialty occupations, while the L-1 visa is used for intra-company transfers.

It's important to note that the work visa application process can be complex and may require thorough documentation and interviews. It's recommended to check the specific requirements and guidelines for the country you plan to work in before starting the application process.
