Similar to the study permit and student visa distinction, "work permit" and "work visa" are often used loosely, but they can refer to different things depending on where you are headed.
The general pattern
A work visa is usually what allows you to enter a country for employment purposes. A work permit is often a separate authorization confirming you are approved to actually work, sometimes tied to a specific employer or role.
Employer-tied permits are common
In many countries, a work permit is issued in connection with a specific job offer and employer. If you change employers, the permit itself may need to be reissued or amended — it is not always automatically transferable.
Some countries combine the two
Certain visa categories function as both entry authorization and work authorization in one document, which is part of why the terms get blended together in everyday conversation.
Why the distinction is worth understanding
Knowing exactly what you are holding, and what it does and does not authorize, matters when it comes to renewals, changing jobs, or bringing family members to join you. Reading your specific documentation carefully — or having someone review it with you — avoids assumptions that could put your status at risk.
