Portuguese temporary residency — valid for 2 years, renewable. Full Schengen Area travel with a Portuguese residence permit.
7 days per year is the minimum stay requirement. You do not need to live in Portugal — only to maintain the investment and spend a minimal amount of time here.
Family reunification — spouse, dependent children and dependent parents are all eligible to apply under the same investment.
Citizenship at year 5 — after 5 years of legal residency maintained through renewals, you become eligible to apply for Portuguese citizenship and an EU passport. Language test (A2 level) and clean criminal record required.
Tax residency is separate. Golden Visa residency does not automatically make you a Portuguese tax resident. If you want to take advantage of the IFICI tax regime (formerly NHR), that is a separate application requiring you to spend more time in Portugal.
