Which Countries Don't Allow Dual Citizenship?

Many Americans belong to two countries, but other nations do not allow dual citizenships. So where is having two nationalities prohibited?

Last year, over 4,000 people renounced their U.S. citizenship. A U.S. passport can be a powerful thing to possess, so why do some people choose to give it up?

In many cases those who've renounced their citizenship from the United States were essentially forced to do so because they were seeking citizenship in another country. Many countries around the world do not allow any of their citizens to simultaneously hold citizenship with another country. In today's Seeker Daily video, we take a look at which countries don't allow dual citizenship.

While no country can technically revoke your citizenship from another country, they can prohibit you from gaining citizenship within their country, or take away your citizen status if they discover you're seeking to become a citizen elsewhere. Some notable countries that drastically limit dual citizenship are: Austria, Germany, Japan, the Netherlands, Norway, Singapore, and Spain, although many countries continue to change and evolve their citizenship policies.

However, it's not all black and white. Many of these countries do allow dual citizenship but only under certain circumstances. In Norway, if you're born in another country and get citizenship there by right of birth but you have Norwegian parents, you don't have to abandon birthright citizenship of the other country to remain a Norwegian citizen.

In Pakistan, you can have dual citizenship, but only from a specific 18 countries. And most middle eastern countries won't allow anyone to have dual citizenship with Israel, under any circumstance.

On the other hand, people that have dual citizenship can actually stand to benefit their country. If you're a dual citizen, typically both countries are allowed to collect taxes from you. In the U.S. that also includes foreign income. So while many global governments may have their reasons for prohibiting dual citizenships, it might actually be in their best interest to allow it.
