6Ireland

Ireland is another country that offers citizenship through descent, making it relatively easy for individuals with Irish ancestry to claim their citizenship. If you have a grandparent who was born in Ireland, you can apply for Irish citizenship. The application process generally requires proof of your ancestry through birth certificates and other relevant documents. 

Having an Irish passport not only allows you to travel to EU countries without a visa, but it also grants you the right to live and work in any EU member state. Moreover, Ireland is known for its friendly locals and vibrant culture, making it a great place to explore your roots.
