Do You Qualify Through Your Grandparents?
Answer these questions:
1. Was your grandmother or grandfather born in Portugal?
2. Or did they hold Portuguese citizenship at any point?
If YES to either question — you likely have the right to Portuguese citizenship through ancestry.
- • Grandparents who emigrated from Portugal to the Americas decades ago
- • Grandparents from the Azores or Madeira islands
- • Grandparents who may have lost track of their Portuguese documents
- • Grandparents who have already passed away

FAQ
Common Questions About Citizenship Through Grandparents
Can I get Portuguese citizenship through my grandparents?
Yes. If your grandmother or grandfather was Portuguese (born in Portugal or held Portuguese citizenship), you may be able to claim citizenship by descent. This pathway typically takes 18-24 months.
What documents do I need for citizenship through grandparents?
You will need: your grandparent's Portuguese birth certificate, your parent's birth certificate (showing the Portuguese grandparent), your own birth certificate, marriage certificates if names changed, your passport, and criminal background check. We can search Portuguese archives for missing documents.
My grandparents came from the Azores — do I qualify?
Yes. The Azores are part of Portugal. If your grandparents emigrated from the Azores (São Miguel, Terceira, Faial, Pico, etc.), they were Portuguese citizens and you may claim citizenship through them.
Do I need to prove continuous lineage?
Yes. You must demonstrate an unbroken chain from your grandparent to yourself. This means showing your grandparent's Portuguese citizenship, your parent's birth, and your own birth. We help compile this documentation.
Is there a language test for citizenship through grandparents?
No. Citizenship by descent through grandparents does not require any Portuguese language test or examination. You do not need to speak Portuguese.
Do I need to live in Portugal?
No. There is no residency requirement for citizenship through grandparents. You can complete the entire process from the USA, Canada, or anywhere in the world without visiting Portugal.
How long does citizenship through grandparents take?
Typically 18-24 months from complete document submission. Cases with readily available documents may be faster. Cases requiring extensive archive searches may take longer.
What if I can't find my grandparent's Portuguese documents?
Our team can search Portuguese civil registries, parish records, and national archives to locate birth certificates, baptismal records, and other documents. Many families are surprised by what we can find.
Can both my maternal and paternal grandparents qualify me?
Yes. You only need one grandparent to have been Portuguese. It can be your mother's side or father's side — grandmother or grandfather.
Will my children automatically become Portuguese?
Once you become a Portuguese citizen, your minor children can be registered as Portuguese citizens. Your Portuguese citizenship will also pass to future generations born after your naturalization.
