If approved by parliament, the new law would allow Dutch citizens to retain their nationality when voluntarily acquiring a foreign one, while foreigners naturalising in the Netherlands would no longer have to give up their previous citizenship.

However, according to De Volkskrant, the second provision has sparked controversy in parliament, meaning the bill currently does not have the support of a parliamentary majority.

At present, adults obtaining Dutch citizenship through naturalisation are generally required to renounce their previous nationality, although the law provides for a number of exceptions.
