Portugal citizenship by descent allows you to claim nationality if you have Portuguese parents, grandparents, or in some cases, great-grandparents. The process involves proving your lineage with official birth, marriage, and identity records, having them legalised and translated if needed, and submitting your application to the Portuguese Civil Registry. Once approved, you’ll gain full citizenship rights — including the ability to live, work, and study anywhere in the EU, access to Portugal’s healthcare and education systems, and visa-free travel to over 180 countries.
