1. United Kingdom
Off the coast of mainland Europe lies the British Isles. There, you’ll find the United Kingdom of Great Britain and Northern Ireland, although no one ever uses the full name. The UK has over 64 million citizens and it has been a member of the European Union’s predecessor, the European Economic Community, since 1973.
In order to become a British citizen, you have to be at least 18 years of age, have no criminal record, and know English and details about life within the UK. You also must live in the country for at least 5 years before you apply for citizenship and spent no more than 450 days outside the UK during this period.
Overall, this is the very easiest of the 10 easiest countries to gain citizenship in EU thanks to the rules it has. It won’t be long before the rules all across the European Union gain a more uniform shape, but you can still use this list to your advantage in the meantime!
