What is the difference between the D7 and the D8 digital nomad visa?

Both are Portuguese residence visas that lead to a residence permit and the same long-term routes, so the choice usually comes down to where your money comes from. If your income is passive and recurring, the D7 is the natural fit, and its income threshold is comparatively modest.

If you are an employee or freelancer actively earning from clients or an employer abroad, the D8 is designed for you, but it requires a much higher income, typically several times the minimum wage. Picking the route that matches your real income source avoids refusals based on the wrong type of evidence.
