Who can apply for Portuguese citizenship?
The routes to citizenship are:
- children of a Portuguese citizen;
- grandchildren and great-grandchildren of a Portuguese citizen;
- spouses or partners in a de facto union (união de facto) with a Portuguese citizen;
- persons adopted by a Portuguese citizen;
- ascendants of a Portuguese citizen, only for applications filed up to May 18, 2026;
- foreign nationals with a period of legal residence in Portugal.
Each route has its own requirements and documents.
Can parents and grandparents of Portuguese citizens still apply for citizenship?
The route for ascendants of a Portuguese citizen applies only to applications filed up to May 18, 2026. Anyone who did not file by that date cannot use this route and should check whether they qualify under any of the other routes to citizenship, such as legal residence in Portugal, each with its own requirements.
How do I know whether I am entitled to Portuguese citizenship through my family?
The first step is to identify which route your case falls under (child, grandchild or great-grandchild, spouse or partner, adoptee, ascendant or residence). Next, the documents are received and reviewed to verify whether the right to Portuguese citizenship exists in the family. This informational content does not replace a review of your specific case.
