A work permit is a permission to take a job within a foreign country. All countries require work permit visas for foreign workers; employers will not hire you without one. It may also be a permit given to minors allowing them to work legally under child labor laws. For select countries, short-term work permit visas are available by application. In other cases, such as for long-term employment, foreign employers will need to apply for the visa on your behalf. Student work exchange programs can legally assist students in obtaining a short-term work permit visa. Unpaid internships and volunteer positions may or may not require a work permit, depending on the host country’s regulations.
