This may surprise you, but more than half the world’s population may not be able to have dual-citizenship. That’s right - over 4 billion people live in countries that generally don’t allow their citizens to be a citizen in another country.
To those of us who live in (the majority of) Europe or the Americas this may seem strange; we’re used to being able to exercise a freedom most would consider pretty normal. With an increasingly mobile world and the desire to hold second passports or live and work in another country, it would seem fairly nightmarish to give up your inherited nationality / passport in order to take up citizenship of the country you may have settled.
What does it really mean?
It’s a complex subject and every country has its own set of rules and exemptions. For example, in Japan you are allowed to hold dual-citizenship up to a certain age before you have to make a decision about whether you want to be Japanese or the other nationality. China technically does not allow second passports / citizenship but in reality, enforcement is weak - but problems could occur in certain situations. Pakistan has exemptions with a number of countries and so on.
If you are interested in a particular country, why not check out our country explorer to see if it allows dual-nationality or see the list below.
So which countries don’t allow dual-citizenship?
The following countries either do not recognise dual-citizenship or have strict rules in place that make it very difficult or limited. Keep in mind that rules change all the time so double check if you aren't sure.
