If you need a Visa to enter The Netherlands and you plan to stay for more than two weeks, you need to register with Alien Police within 72 hours of arriving in The Netherlands. Not all Nationalities are required to register with Alien Police. It is recommended that you check the Immigration Website to confirm whether you are mandated to report to or not.
If you plan to stay in The Netherlands for a period longer than four months, you will need to register with the IND. Please check the IND website for more information. www.ind.nl
