Everyone who wants to adopt Dutch nationality will soon have to give up their original nationality if that is legally possible, home affairs minister Piet Hein Donner said on Monday.

At the moment, for example, people who marry a Dutch citizen can keep their original nationality if they decide to become Dutch as well.
‘Dutch citizenship is the crown on participation and integration into society,’ Donner said in a briefing, outlining plans to toughen up the rules on becoming Dutch. The new measures were included in the coalition agreement.
Language tests
The minister is also planning to introduce compulsory language tests for everyone. Some people are currently exempt.
New Dutch nationals will also have a family income of at least the minimum wage and show that they have at least two years work experience or have some sort of professional qualification.
The minister has opened an internet portal where everyone can comment on the proposed changes.
In four weeks time, the draft legislation will be sent to the council of state for its assessment.
