Can I be penalised for helping an undocumented person?
Help with illegal residence that is not provided in pursuit of profit is not punishable. Help with illegal border crossing is always punishable according to Dutch law, but during the deliberations in the Dutch Lower House the Minister has made it clear that humanitarian grounds will always be taken into account.
If you provide housing accommodation to undocumented migrants you should report this to the police in all cases. You can get a fine if you don’t report this.
