Does the EU Blue Card work for Portugal?

Short answer: Yes — EU Blue Card is a parallel track for highly-qualified employees with a binding Portuguese job offer paying ≥ 1.5× the national average.

The EU Blue Card is filed via AIMA (no consulate step if you're already legally in the EU), gives faster intra-EU mobility than national permits, and counts toward 5-year permanent-residence eligibility. Best fit for senior tech and research roles.
