In a country notorious for its exclusive immigration policy, the question of whether to allow Japanese to hold dual citizenship became a surprisingly hot policy topic last year after members of the ruling party breached the issue.
In many other parts of the world, it’s a matter that has already been discussed in great depth, and observers agree that an increasing number of countries are moving toward allowing citizens to become multinational.
As of 2000, around 90 countries and territories permitted dual citizenship either fully or with exceptional permission, according to the “Backgrounder,” published by the Center for Immigration Studies in the United States, and “Citizenship Laws of the World” by the U.S. Office of Personnel Management.
Since the reports came out, several countries have lifted bans on dual nationality. As a consequence, there are more than 90 countries backing dual nationality by default today.
“The trend is dramatic and nearly unidirectional. A clear majority of countries now accepts dual citizenship,” said Peter Spiro, an expert on multi nationality issues at Temple University Beasley School of Law.
“Plural citizenship has quietly become a defining feature of globalization.”
Countries such as the United States, Canada and the United Kingdom who go by the principle of jus soli, which gives nationality to everyone born on their soil and territories, have long been lenient in permitting dual citizenship.
The shift is also being seen in countries that have traditionally adhered to jus sanguinis, which says that a child’s nationality is determined by his parent’s citizenship.
