A work permit is an official document that allows a person to work legally in a specific country. It is often required for foreign nationals who wish to take up employment in a country where they are not a citizen. The permit typically outlines the type of work the individual can do, the duration of employment, and any restrictions that may apply. To obtain a work permit, applicants usually need to provide proof of a job offer from an employer, along with other necessary documentation. Different countries have varying regulations and processes for issuing work permits, which may involve applications through government agencies or embassies.
