What is the D8 (and the two versions you must choose between)
The D8 is Portugal's national visa for remote work, officially aimed at people exercising a professional activity remotely for an employer or clients outside Portugal (source: MNE). It has become the standard Portuguese answer for the remote workforce: employees of foreign companies, freelancers with foreign clients, and founders paying themselves from entities abroad. Per the MNE, it exists in two distinct forms:
- Temporary-stay D8: for stays of under 1 year. It allows multiple entries, is valid for the entire stay, is not extendable, and leads to no residence permit.
- Residency D8: a residence visa valid for 4 months with 2 entries, during which you enter Portugal and apply to AIMA for a residence permit.
Choosing between them is the first fork in the road:
The decision rule is blunt: if Portugal is an experiment, the temporary-stay version is simpler and keeps you mobile. If Portugal is the plan, only the residency version starts the clock toward permanent residency and citizenship.
The wrong choice is expensive in both directions. Take the temporary-stay version when you actually want to settle, and you lose months: it cannot be extended, gives you no permit, and when it expires you start over. Take the residency version when you will not really live in Portugal, and you inherit presence obligations you cannot meet, which surfaces at renewal. Pick the version that matches your real life, not the one that looks easier on paper.
