If you decide to move to the Netherlands, you will of course want to bring your partner and any children you may have with you. If you are an EU citizen*, you will not need to request a residency permit for you or your family. That being said, every member of your family that is moving with you will need to register with the Dutch Citizen Registry (BRP in Dutch) as part of the municipality you will be living in.
*including Norway, Iceland, Liechtenstein, and Switzerland
One of the most important things to know when moving to the Netherlands with children is that in the Netherlands, children’s education is compulsory. All children living in the Netherlands are required to attend primary school from the age of four. Your child is unlikely to speak the Dutch language by then and may have a hard time making friends. Some schools are experienced with teaching children that do not speak Dutch yet – ask at your local schools to find out how they deal with teaching foreign children. Also consider the fact that the younger the child, the easier it will be for them to learn the Dutch language.
Some schools have waiting lists, so you would do well not to wait too long to sign up your child!
