Do grandchildren now need to speak Portuguese?
Yes, you need to show knowledge of the Portuguese language, culture, history and national symbols. People from Portuguese-speaking countries are presumed to know the language. How others prove it will be set out in regulations that hadn’t been published by September 2026.
Does my parent need to become Portuguese first?
No. As a grandchild you can apply directly. You still need your parent’s birth certificate to show the link.
Can I keep my current passport?
Yes. Portugal allows dual citizenship, and so do the UK, US, Canada, Australia and New Zealand.
My great-grandfather was Portuguese. Is there any route?
Only by living in Portugal legally for 5 years. The government may then grant nationality, but it’s at its discretion.
Once I’m Portuguese, can my children be too?
Yes. As a grandchild you become Portuguese by origin, so your own children born abroad can then use the simpler route for children of Portuguese citizens.
Will I have to do military service?
No. Portugal ended conscription in 2004.
