Spain — Skilled Migration
Not eligible
You do not need any of this. As an EU, EEA or Swiss citizen you have the right to live and work in Spain without a visa, a permit, an employer sponsor or an income threshold.
What you do instead is register. Staying beyond three months, you register on the Central Register of Foreign Nationals and receive a certificate with your NIE — you will need it to work, open a bank account, sign a lease or be paid. Register on the padrón at your local town hall too, which underpins access to healthcare and local services.
For work itself, your qualifications may need recognition if your profession is regulated in Spain — medicine, law, teaching, engineering and others. EU mutual recognition makes that more straightforward than for non-EU qualifications, but it is not automatic and it is the thing most likely to delay you actually starting work. Begin it before you move.
The questions genuinely worth your attention are tax and social security rather than immigration. Spanish tax residence generally brings worldwide income into scope, and where your contributions are due depends on EU coordination rules and how your employment is structured. Both are easier to set up correctly than to fix afterwards.
On citizenship: EU nationals naturalise on the same terms as everyone else, which means ten years of legal residence — Spain does not shorten it for EU citizens. It is two years if you are a national of Portugal, or of a Latin American country, Andorra, the Philippines or Equatorial Guinea, so if you hold more than one nationality that is worth checking.
